General Audio

I have a cobalt that comes with the battery in the trunk stock. It was grounded to a piece of sheet metal that was spot welded to the wheel well. I had to remove said piece to fit the 2 extra kinetik hc16v running off the second alt. Any way i have all the batteries grounded with 2/0 to one spot (sheet metal) and the amps hu and processor are also indirectly grounded to the same spot. The only thing audio wise not connected to this one spot is the second alt which is grounded in the engine bay instead. Even as such I've experienced tons of ground loop. So the past few weeks I've spent rewiring my car and doing some tricks to eliminate the ground loop. The hard work paid o…

I have a 99 toyota camry with 2 fi q 12s on a saz 3500v2 I was wondering if anyone has had any experience with camry. I have my subs & port firing to the rear & it is not bad but I was wondering if anyone has had the subs firing forward & port to the side & how it did vs. sub & port to rear. I am having a slot port built right now just wondering if anyone had gain or improvement doing this in a gen 4 camry. I am just looking for a suggestions I know ultimately I am going to have to just experiment because of all the uncontrollable variables. Here is my question do you think I should go for it & try subs forward port to passenger side or stick with…

my comp set

Hi, I have a 1999 blazer with a single 12 Fi Q powered by a cadence zrs-7000d which is running at about 1300 rms at 1 ohm. The Fi Q is in a 2.2cuft L-Ported box tuned to about 32 hz. I really like this sub woofer but i am looking for more output. I have some questions now. First, i am looking to add another Fi Q 12 and making the box to about 5^3, i would be buying another zrs-7000d and bridging them together to get 2600rms at 2 ohms. Would there be any better subs that would give me noticeably more output out of a 5^3 box with about 2600rms? Second, would a new 250 amp alt and a optima yellow top under the hood be enough to support the electrical for the 2600watts? Third…

Playing in the 10"port..

I was looking for opinions on a how many batteries or Ah ( amp hours ) would people use to supply 20-30,000 watts? Fyi 2-300 amp mechman alts supplying the bank and 4-cresendo 5500 sub amps in use.

Whats happening at the build house that everything has an eta of july i believe? A little dissapointed by this... are they that swamped?

i need box builder for my subs this is what i need Here's the box info. Sealed box 2.4 cubic feet Line box with ~3" thick fiberglass insulation. Subs faced up. if anythin hit me up here or [email protected]

Hey guys i think I'm in the right area of the forum to post this but if I'm not, my bad. I bought two Fi BL 15s fully loaded with the daily option a few months back. Originally I was going to buy a Sundown or Cresendo amp but money is tight so I've been looking into the Hifonics BE 2500.1. I know they have a bad name, but I currently own an older series Hifonics BXi 2008d and honestly love the amp. Don't get me wrong I've had it repaired about 4 times but all due to inefficient power supply. The new series is CEA compliant and Steve Meade proved they do put out the power advertised. With that being said, do you guys think a 240 amp Mechman Alt could power the 2500 rms am…

Im planning on putting 2 batteries under the hood for my 1990 mazda b2200 sound system soon. Gonna have little over 4k watts rms, i already upgraded the alternator to a 300 amp. I could get optima or diehard platinum cheap from my friend but im open to other brands.

im going to post a link i hope thats ok with u guys thank u let me know what u think http://www.****/forum/s...0832#post160832

Wondering on the average time

Here a few pics of finished install....

I have been looking every where for loose fiberglass strands or kitty hair but all I seem to find is matts. Any one know where I can find it?

...and it smells funny. That is all.

my monoblock for my btl my 4 channel for my frontstage my ABSOLUTELY BEAUTIFUL orion HCCA millenium edition 2 ohm 6.5" midwoofers. i spent a small fortune on these, the gonzos, and the crossovers; but very much worth it. my robot underground gonzo 2" aluminum tweeters my a/d/s A6is cross over networks (with 2 ohm lowpass mod) my RE-69FR 6x9 speakers in some nice boxes Still waiting on my sub box as well but every one please go check out Josh Salrin at www.finecustomworks.com, he makes the nicest and highest quality boxes you could imagine, shoot him an email and he will hook you up with any box you want, you choose every last detail and customization possible t…

Ok this is one of my first posts and I'm pretty audio ignorant so bear with me. I have a 2008 silverado duramax crew cab and a sundown 1200 mono amp. I know the box has to go under the seat unless I do crazy customization so there isn't much room. The box that has been recommended to me by a few people is this one http://subthump.com/Chevrolet-GMC-Sub-Boxes/Silverado-Sierra-Crew-Cab/07-Up-New-Body-Style-GM-Crew-Cab-Dual-Downfire-Box.html It holds 2 10s and has a mounting depth of 6.5 with .83 ft per chamber and it's sealed. Downfiring. I know a g con and a sa10 would fit but the sa 10 requires .5ft while the gcon ranges from .85-1.25. I need to know what two subs would …

I am about as new as a newbie can get to car audio and the use of forums so if I am annoying anyone I apologize in advance. I am pretty frustrated at this point cuz i cannot find an answer anywhere so here I am. I bought a 15" xcon from a guy who was going to help me set up my system but he literally went mad and is currently in the state hospital. he told me to get a Hifonics Brutus brx2416.1d super d class mono amp which i did. He also told me that this sub is half ohm and thats about as far as we got before crazy happened. So now due to his mind frame I question if I got the correct amp and if so how do I wire a half ohm sub to a 1 ohm stable amp without damaging amp. …

I want to say it's a late 90s Yukon suv the only thing I need help with is figuring out if I should try and budget for as most cone area as possible or highest quality sub I can get like 8 12inch pioneer subs or 1 hdc4 18 keep in mind he probably isn't going to want to upgrade alt and batts so I'm working with about 1000rms if that also that he probably don't want to spend alot

So JL is garbage but NVX is nice? This one sentence has told me all I need to know. No offense but NVX is cheap Taiwan stuff that's not gonna sound very good and sure isn't gonna hold up well guranteed. I do like the other brands SSA caries I own crescendo and sundown myself so I know there damn fine products. And I have no problem with cheap affordable products for beginners or someone on a budget but I can see now how biased M5 is if he thinks JL is junk and a cheap Taiwan brand is nice.

so i was wondering its easier for me to make payments over a period of time than it is to save the money to buy quality like sundown or fi. do any of these companies do that?

wats da deal with the Pioneer AVHP5050DVD unit, Cant find info nowhere on it.

My friend currently just got his first system. Its a 12" CVR with a 2.7 cuft. sealed box. The power is coming from a TXi 1008D (1000 watt) Hifonics amp. Now heres the issue. This system does NOT pound at all. It feels really "weak" if you say. Someone told me that the box is too big. Im not really sure. Heres a hint, when playing hoods run down, it doesn't get the last 3 tones. Its as if the sub is not even trying, there is no excursion at all. Any one have any ideas? Thanks. Heres a pic of the box for the hell of it.

After being out of car audio for a couple years now, I got the bug again. I recently bought a 2004 Toyota 4Runner and have factory speakers all the way around. The only upgrade I have done is install an Alpine CDE-W265BT. The drivers door speaker is making noises, and there are some annoying rattles that need to be addressed. I figured while I try to find the annoying rattles and replace the blown speaker, I will do some proper deadening and install a new front stage. This system will be for casual listening. No competitions and I don't care a tone about getting really loud. Sound quality ismy number one priority. So here's what I have and my initial id…

i need some guidance here. I'm looking at a 2 way 10" mid bass with horn setup, the 10's I'm looking at seem to go up to around the 800-1200hz range so the horn needs to handle around 1k and up. i found some limited information from 07 on how a setup would work and from what i gather i want the horns positioned under the dash and firing parallel to the floor? with some processing i should be able to raise the sound stage up to about dash level? i also read that the width will more than likely be less than the distance between the a pillars if i don't add any other tweeters and that the horns would benefit from a 16khz and up super tweet? ive never done a horn…
