2005 Silverado crew cab

[hdrox88 142]

Replaced plugs and wires today. Also got the Singer in place.

Factory alternator and battery location will continue to run the factory systems for the truck. The Singer alternator is wired up and charging the battery in the secondary under hood location and will charge additional batteries and power the amps.

Cold start

Nice!

Made some progress today. Rear seats are out. Built a false floor and fitted the batteries.

I like that false floor with the batteries.  It gives me ideas, as I need to hide mine.

No more back seats finally ! 

 

[hdrox88 142]

Got everything playing finally. Zip tied everything in place before the console went back in place. I removed the duct in the console for the rear air so that it vents air into the console. Refrigerated amplifiers!

Temporary bass setup so I can take my time with the box and stretch the legs of the fresh recone a little bit.

[hdrox88 142]

Finally got to work on the box. 8ft^3 @ 28.5hz with 130in^2 of port. I went a little lower with tuning as the response of the xcon in the crew cab is playing much higher than it did in the tahoe. I'm hoping to counter that and play down to the mid to low 20s well.

[hdrox88 142]

It's taking shape, I just need to figure out how I'm going to finish it.

I wrapped the false floor today. Not an exact match to the factory carpet, but it looks tons better than the bare wood.

I regret this tweeter placement. It looked good in my head, after actually doing it I'm less than pleased.

[hdrox88 142]

Well, curiosity got the better of me and I loaded up the xcons in the box to see how it sounded before I spend the time finishing the box. My roof is flexing bad, making terrible noises and killing mid to high 20hz notes. 20-21hz is fun, then it dies off til about 28hz and plays well up into the 60s. Anyone have any experience with the roof in these crew cab trucks? No sun roof either.

[Aaron Clinton 2,372]

Coming along nicely!  Those PPI's are tiny.

Sure the roof is killing them?  It should at lower levels too then which you can counteract with your body.  Like anything that flexes it needs a heat converter and a stiffener if it is real bad.

[hdrox88 142]

At lower volume it plays fairly flat. As I turn it up, there is a point where the roof starts flexing/resonating making it's own music and that is when the frequencies in the 20s don't get any louder while the rest of the sub bass frequencies will continue to increase as I turn the volume up. My back wall/window gets going as well when this happens. Hell, the panel of the bed next to the back wall of the cab flexes now too. Who buys multiple large subwoofers anyway?!

[///M5 2,833]

Have you tried just playing single frequencies to see the same effect?  It should help you "localize" the problem.  Quotes are because it won't be so local...

[hdrox88 142]

No, I haven't tried that. Will have to see what I find. Anything in particular to pay attention to when doing so? Will probably start by placing towels and heavy weight on the roof to reduce it moving and see if that changes anything.

One of the requirements, or must-haves, with a loud ground pounder is body bracing. Personally,  I'd sand the paint off the exterior roof then weld 1/2" angle iron across the inside of the roof. It wont be easy, you'll need to heat the angle iron with a torch and form it to the contour of the roof. Then you will have to repaint the roof. You came this far...

[hdrox88 142]

I kinda figured welding in some bracing was in order. I just need to decide how far I want to go with this one. My Tahoe sounded excellent without much effort. This one is proving a little more difficult to get the response where I want it. Definitely loudest I've had so far though. Making me giggle every once in a while again.

 

If I pull the headliner and brace the roof, I might as well just wall it. Oh dear, what am I getting myself into?!

I think 2 more xcons and a wall is in order

Too bad you dont live near me, I'd love to help. That would satisfy my desire to do it to my own vehicle!

I need that bc3500 crescendo amp you have. I can't seem to find one any where. What's up with that?

Don't temp me.

 

I decided on a finish for the box, failed miserably on the execution. It was supposed to be a dark grey hammered metal texture. I think it was too hot and it dried before it could separate to create the effect it was supposed to achieve. It came out a lighter grey and more of a gloss with a little orange peel to it. Oh well, at least it's not bare wood anymore.

[Billy Jack 145]

Looks pretty good to me but I'm not there in person. If it looks good from 10 foot away I call it good. My new car and build has a couple of flaws but from 10 feet away it looks perfect. It's hard to keep a daily driver perfect. I met my woman at a store one day in my work car and she was driving our show car and sure enough a guy in a huge full size suv backs right into the show car setting 3 feet from the hooptie work car and just drives off. I was so pissed I was like he could have totaled the work car and I wouldn't have cared but he nails the one that cost piles of money then speeds away. We watched the stores cameras but he had a plastic cover over his plate so you couldn't read it. Bastard he was.

Looks like I forgot to upload these pics when I finished the box.

[frogcase2002 393]

Yea if you are not using the back seats anyway you mite as well wall it

[hdrox88 142]

If only I had the funds for it... Looks like it's time to start saving!
