1992 Olds 88 Royale LS - Build on the Cheap(er)

Recommended Posts

Okay, this little build will be going into my 1992 Oldsmobile 88.  I bought the car about 7 years ago right after I started working for the pipeline I'm working for now.  I got a hell of a deal on it and got it so that I had a car just for driving to work so my wife would still have the van to drive at home.  I only drove the car for a couple of years before I bought the Jimmy and right after that I gave the Olds to my mother and father in law to drive because their car broke down and my mother in law was having to run around to doctors and things for her cancer treatments and such.  Well fast forward from then and I find myself with the Jimmy out of commission and my father in law wasn't driving the Olds anymore because he had gotten his own car.  So he gave the car back to me so I could have something to drive to work again.  

 

Just before I gave the car to him to drive I had dropped an OLD Pioneer CD player I had bought used on Ebay for $20 to put in the car because the factory radio didn't work.  I also put a pair of Hifonics Zeus Components I had lying around from another project in the rear deck in place of the bad factory 6x9's.  It still sucked but it made music.  Now after driving the car awhile again I've gotten fed up with the damned thing.  Only one of the mids in the Zeus components are working anymore and the front factory tweeter/mid thing in the front doors are shot.  So I've picked up a little bit of stuff I got for cheap and I'm hopefully going to get it sounding better than it is right now.  I'm also going to use this little build as an experiment as well on some ideas I have floating around in my head.

 

 

 

The equipment going in:

 

Pioneer DEH-X7500HD - Used a discount I had on hand at SonicElectronix to get it for under $80

 

Aura 4x6 coax's - On clearance at PE.  I don't normally mess with oval speakers and such but for their clearance price I wanted to try them out.  Going in the front doors.

 

Dayton SD215A-88 - Used a promo code here and got them for $19 each.  Going to use the pair as dedicated midbasses in the rear deck.

 

JBL GTO1004 - Already have it on hand, will use it's internal crossovers to run the Aura's up out of harms way and utilize the Dayton's in the midbass range.

 

 

 

We'll see how it turns out.  It should be a fairly quick and easy build.  The goal is simply to get something that sounds reasonably good with better overall response than it has now and able to get more volume out of it than it can produce now, especially without the front speakers sounding like they're going to puke on every drum hit even at low listening levels.

Thanks.  It shouldn't be too shabby.

 

Going to treat the 4x6's like fullranges, or toss one of the full range sets I have lying around in.  We'll see which wins the toss up when I test them out.  Since it won't and can't be on axis the 4x6's will probably be the ones to get used.

Okay, got all the last of the equipment and wiring today!!  I should be able to start tinkering with running the wires and working on installation of the gear tomorrow if I can get a few free moments at work.  I modeled the Dayton's in an IB environment vs. a .6cuft sealed enclosure and there's almost no difference in output so they should be pretty fair used that way.  

 

 

Anyway, here's a pic of the stuff.

I absolutely HATE my luck.  Moments after posting this we found a broken head stud on one of the units.....   There goes tomorrow......

It turned out not to be too horrible this time.  Usually it takes a day, sometimes two to get those hardened steel studs drilled and broke loose.  This one cooperated remarkably well.  I got pictures uploading to the bucket now.

 

Thanks on the compliment.  It's nothing special though, just enough to be a decent bit better than what's in there now.

Thanks man, though I don't think this build will be particularly noteworthy as it's going to be as simple as I can stand to make it.  A little sound deadener, some custom baffles, and an otherwise stealth install with about the cheapest stuff I could find to meet my goals is all that's going on with this one.

 

Eventually I may drop that 12" sub I tested awhile back in it just to get some use out of it but that will probably happen later on.  I am going ahead and buying Sean's PPI S850.1 for the purpose though.  :D

Nice equpiment. I was hoping to see the car ...

 

 

I was hoping to hide it for as long as possible, lol.  It really is just an old beater of a car that will probably be the first car the kids drive as they get to that age.  My daughter is 15, turns 16 right around Thanksgiving and will need something like this to start driving in but for now I'm driving to/from work until I get the trans replaced in the Jimmy.

 

 

 

Here's shot of the car since you asked nicely, lol.

I got a chance to start on a few things yesterday.  I was only able to get a few feet of the RCA's zip-tied together and the inter coil connecting wires for the DVC's on the Dayton's soldered on but hey, progress is progress even if it is only little steps.  Here's a couple pics of the wiring on the Daytons.

Here's a shot of stock speaker location on the door panel.  I've got to tear into it further to see exactly what I'm up against but since this is a simple build I doubt much more will be done that just reinforcing the stock mounting and tossing the speakers in.  It would take more work than this level of build deserves to do anything much better for the speakers.  Maybe in the future if the car ends up staying with us for a long time but right now I just can't justify it.

Spent a little time this weekend tearing into the car to see what I was going to be up against.  The damned doors on this thing are more deceiving than I had originally anticipated.  They used what looks like a 5.25" mid at the bottom of the door and a tweeter up behind the 4x6 grill.  I don't think I'm going to let that deter my plans at this point and will still be building a baffle for the 4x6's to fit behind that spot in the door.  I am going to make an attempt at angling them and I'll probably cut out the opening on the factory grill so that it doesn't affect the response and will cover it with regular grill cloth for a nicer looking finish.  As for the 8" Daytons I'll be building a double thick 3/4" baffle to go on top of the rear deck with the baffle step cut so that the driver is recessed well below the surface of the 1.5" thickness of the baffle.  On the bottom of the rear deck will be another baffle board spanning the length of the deck to add more rigidity to the deck and mounting for the Dayton's along with giving a solid surface to mount the amp to.  Of course upside down isn't ideal for cooling but this amp shouldn't ever be getting ran hard enough for any real heat to become an issue.

 

Here's some pics of what I found on the doors and of the mounting I did for the cheap and horrible sounding Hifonics Zeus components I had mentioned at the start of the thread.

 

 

 

Here is a door without the panel on it.  Sneaky bastards, lol.

Here's the top of the rear deck with the baffles I had built to fit the components over the 6x9 holes.  As much as I hate 6x9's a cheapo set of Pioneer 3 ways from Wal-Mart would have sounded better than these crappy components, but I used what I had on hand so I can't complain a whole lot.

Last but not least a shot of the bottom of the rear deck.  As mentioned before there will be a board going all the way across and the amp will be mounted to it.

I'm hoping to dig into this and get some work done on it pretty soon.  Now that I think I have a good game plan, some measurements will follow and the work will begin.

Another update.  Got some wire ran this morning.  I was able to get the speaker wires for the front doors and the RCA's ran from the front to the trunk and got the drivers side trim all put back in.  I got the fuse mounted and the power wire ran from the battery through the firewall and left it with silicone sealant on the grommet to set up while I eat lunch.

 

I find it hard to get pictures while I'm in the middle of doing work.  I just get too involved, but here's some pics I got when I could and after I got some of this done.

Looks like it should go together rather easy with your skills. Knock on wood nothing else gets in the way. :P

More updates!

 

I was able to get the power wire ran and the passenger side put back together, the rear deck deadened, then covered in CCF, the top baffles made and installed, the amp rack/bottom baffle made and installed, the Dayton's installed and the back half of the car all put back together here before the end of the day.  It's not the prettiest job in the world but it should serve it's purpose quite well.

 

Onto the pictures.

 

 

 

 

 

Here's the rear deck as it was when I found it without the crappy Hifonics Zeus components in it anymore.

 

 

8445FDE4-36B4-472F-A009-FA0AAFB280B6_zps

 

 

 

 

 

Since the factory deadener was still well attached I went ahead with covering it at the mounting holes with some old RaamMat BXT I still have a roll of.  

 

 

21D9E582-D3C1-4E2F-AF81-DE9C5C632930_zps

 

 

 

 

 

I covered that with some IUO peal n stick CCF that's just as old as the roll of BXT that I had lying around as well.  It's not the greatest stuff in the world but for this project it's just fine.

 

 

6C701ED4-9269-4396-869E-352C2CA64C25_zps

 

 

 

 

 

I cut the baffles out from scrap left over from building the box for the XCON in the Jimmy.  In the interest of getting this job done quick I just shot the holes out with a jigsaw and I glued and nailed them together real quick but I think they turned out pretty darn good.

I test fit everything then screwed the top baffles to the rear deck from the bottom, then screwed the bottom baffle/amp rack onto the bottom of the deck.  Then I went ahead and mounted the Dayton's.  Just in case you're wondering about the CCF over the baffles, I did that to reduce the chance of having any rattles from the deck cover slapping the baffles.  I hope one layer is enough.

Finally, here's what it looks like with the back of the car all put back together again.  Can't even tell all that crap is hiding under there.

That's it until I get another chance to tear into it.  I'll be mounting the amp, installing the HU and fabricating some way to mount the 4x6's to the door panels.

Thanks, and neither can I!  It's not going to be anywhere near perfect.  Cheap speakers, cheap HU, no DTA, etc. but that was never the goal anyway.  It should be worlds better than it was and with any luck it will actually sound pretty decent.

Alright, a few more updates.  Got to start working on my idea to mount the 4x6's to the door panel at an angle.  I'm not sure how well it's going to work, or fit for that matter, just yet but again I just made this stuff out of scrap so if it doesn't work out I'm not out anything but a little time.  I built a small box just large enough to rear mount the 4x6's from the back side and split it into two pieces at an angle to create the mounting angle for the Aura's.  As long as everything works and fits they should work out great.  I also began to remove some of the factory grill so that it doesn't affect the sound so badly.  Once those are done I'll be wrapping them in matching (or close enough to matching) gray speaker grille cloth for a nice finish.

 

 

Onto some pics.

Here's the factory grill.  It's a delicate operation drilling out each of those parts of the grill to leave the honeycomb looking reinforcement part of the grille to back the grill cloth.

      Am currently looking at subwoofers to upgrade from my lowly Powerbass S-10D's. Have been running a Lightning Audio 1001.d monoblock @ 1 ohm for the last year, and every time I get it cranking, the amp shuts off after 10-15 minutes, blowing fuses. I am running a 250 amp alternator, and a brand new 1000ca/800cca battery, with 1/0 run back to my distribution block, and a 14" 4ga run to the amp, with the big 3 under the hood. Will be adding a second battery, under the hood, as there is a second battery tray. I really don't want to run much more power than what I already have, as I don't want to get into having to add a dual alternator, or putting another battery in the back. Probably looking at a1200-1500 watt amp, possibly Skar or Audiopipe, just depends on what I can find for a deal.
      The Powerbass subs are only rated at 350 watts rms, I'd like to be able to run a clean 600-750 to each. I haven't found much out there for a sub that has a high sensitivity, other than the Dayton's below. Most 10" subs that can handle 500 watts rms or more only have a sensitivity from 83-87db, these Dayton's are supposedly 90.5db. If I remember correctly, it takes double the power to achieve 3db more in output - if that's so, then these Daytons with 600 watts would have the same output as a different sub pushed by 1200 watts at a 87.5db sensitivity, or 2400 watts pushing a sub with 83.5db sensitivity.
      I know that Dayton is primarily a home audio company, but these have me intrigued. Specs look decent, and what other content I've found online seems to agree.
      If not these, then make another suggestion for a higher-sensitivity 10" sub, that will work in a 1.25-1.3cu ft enclosure (mine is about 2.8 cubes, less sub and port displacement).

      One of the biggest and most powerful amplifiers ever made. They didn't make very many of these so they are quite rare. one was recently tested by oldschoolstereo.com and made over 12,000w rms between the two channels at 1.6ohm per channel. Here is the link I recommend watching it as he goes into the history of this huge amplifier.
      And here is the manufacturers underrated specifications:
      Output Power at 14.4V and ≤1% THD+N (CEA-2006):
      2 x 2600W @ 4 ohms
      1 x 8110W @ 4 ohms
      1 x 7400W @ 1 ohm
      S/N Ratio: 65dBA (1 Watt, 4 ohms)
      Effective Damping Factor: 6.39 @ 4 ohms
      Freq. Response: 10Hz ∼ 270Hz (-3dB)
      Fuse: 600A internal (external 500A minimum)
      Dimensions: 29.38" x 23" x 6.5" (74.6cm x 58.4cm x 16.5cm)
      Weight: 88 lb.
      Only selling because I'm moving agian and need the extra space. The top beauty/mounting plates are in automotive primer ready to be painted to match your build.
      Condition is excellent. Price is $1500 picked up in the Dallas Texas area, or best offer, don't bother low balling Id rather keep it to be honest. It's only going to gain value considering how rare these amplifiers are getting. I would be willing to ship it if you cover the costs for shipping. Call or text me  for questions: 907-227-8213
