General Audio

i have a wierd problem i just installed o ga wire under the hood for the big 3 and now i have a really bad ground problem like i hear when i hit the brake pedal even the turning signal and cant understand it. i grounded it to the frame and vehicles factory location also sanded them to bare metal... and just the other day now if i turn it up to a certain volume it sounds like the woofer flop or play out of tune thats why i was thinking it might be the rca's any help appreciated.... i run 2 12'' q's on a everest soundlabs prototype amp box is 5 cuft and tuned to 30hz

Hi all- I have been battling with alternator whine for a majority of my car audio hobby. I have tried countless things. I had just made an LC filter to filter out noise in the power line of my radio thinking it was finally it, but unfortuately it remained. Then it dawned on me, I have 2 amps for speakers in my car now and I tried disconnecting the one I've had for years. The noise went away, which is great to finally know what is causing it. The problem is I don't have the cash to buy a new amp for my midbass. Does anyone have any idea where to start troubleshooting inside the amp for something like this? I'm a fourth year electrical engineering student, so I'm quite …

Hello, I recently received a 12" btl. I put it in a well built box (I have pics in the build log section), on a Sundown saz 1500 amplifier. I had a weird noise coming from the speaker at my max volume. Even if I did not change any settings from my previous setup (I had an xcon 15" on it with NO problem), it seems that my gain was too high. I turn it down and everything is good now ! But I want to find good sounding test tones to set the gain right on the amp. Can somebody show me where to find some ? I think in the 50 to 60 hz range. I set the gain by ears, and I will try to see what I can do with a DMM for that. Thanks in advance.

A buddy of mine is looking to upgrade his audio, and between him and I we are trying to get some ideas about what to buy. He has a new(ish) (2004-2006 probably) cadillac escalade. Not positive of the max dims, but I can get exacts if necessary. I'm just assuming similar to most other large SUV's. He is running his stock head unit but willing to upgrade if necessary, which will most likely happen. He is considering (2) 18's or maybe even (4) 15's or 18's. I am looking for suggestions as to what subs and amps to buy, but even more so to what else is necessary to accomodate such a large amount of RMS. He is running his stock alt. So, besides the Big 3 which I know he wi…

I'm in the process (literally, just came upstairs to ask this question haha), and i was fitting my marine terminals to my battery. I'm not sure if its a problem, but they don't go down all the way, and even if they could, the bolt wouldn't be able to go through because the holes for it would be so curved. When i bolted it down, it wasn't going anywhere, i'm not worried about that. I'm just not sure if it has to be at the very bottom for the least resistance and best flow So can i leave as is? or should i get new terminals (though i didn't see any bigger than what i have now).

since the ultimate installer is avoiding me, i need a new installer here in the pittsburgh or surrounding areas. must know how to cut wood to build sealed and ported boxes and mdf rings for speakers, running wires for systems and possibly fiberglassing. please tell them to e-mail me at [email protected] or to send me a pm here.

Are they ok to use as a primary and secondary??? I can get a great deal on 2 blue top Optima Battery's. I want to use one under the hood (for the truck), and a second one inside (for the system).

basically, i've had a major drop in bass in my car. i have 2 fi BLs and 2 kicker 1000w amps. initially, i had trouble with my iPod cable(dock to aux cord , the 7$ one from ebay) so i bought a new one. well now all of a sudden, my cds have also lost the quality. the stock speakers in the door hit harder as of right now. when i turn the knob all the way and put the volume up, i finally get what i should be getting at about 1/4 turned. i looked at the amps thinking 1 of them was dead and they both were fine. i dont really know much about wiring but will probably read up on it 2morrow since i will have some free time to look at it, but this is what basically happens http://pi…

Ok, So. I'm going to be getting a 1989 Jeep Cherokee sport soon here, and plan to do a decent build with it. One that I can afford of course. I don't really have a set budget, but I'm just looking for some certain things, and will amass the money over this summer. First of all, I already have a sub for the car, which is currently in my room. 18" Fi SDD (copper coil only) w/ a 9cuft box @32hz. Sounds fantastic off of my receiver in my room. I'm sure it will sound even more fantastic inside of a vehicle with the right amp. I also already have a head unit I got from a friend for cheap, a Pioneer DEH-2100IB. Right now I was looking at the Sundown SAZ-1000D. Seems to be a per…

finally, something done the right way. i just hope they now go on to create a law that is constitutional and actually does what it should, which is take care of the pricks that bass heavy in neighborhoods, disturb the peace, etc. http://www.orlandosentinel.com/news/local/os-loud-music-law-unconstitutional-20110512,0,4161161.story

I bought all of Johnathan Prices' old component sets for a real good price, a few of the crossovers were….. well shitty and unusable. But I am MORE than ok with that. My question is, could I run 2 mids & 2 tweets off one crossover? I wired up a 2 mids & 2 tweets to a crossover to check the ohm load at the “input” space and it was at 3.44ohm. If not then I’ll just run the tweets off radio and mids off 100.4 till I find a cheap 50.4.

so i went to hook up my set-up. got everything hooked up, but there is extremely little output from the sub. i can barely hear the bass, but if i set my hand on the sub i can feel it moving just barely. when i went to hook it up the 1st time, i forgot to unhook the battery. when i put in the power wire it sparked and the protection light flashed. then i disconnected the positive battery terminal, hooked up the ground, remote, speaker, RCA's, gains knob, power wire, then positive on battery. hooked everything up in that order. turned the HU on to 10. could barely hear the bass. and like said above when i put my hand on the sub i could feel it moving slightly. played with …

my cuzn owed me 250 dollars and instead he gave me a amp its the mtx 801d 800 watts rms,anybody use this amp before or know if its a ok amp?

Quick question. What is better having 1 big amp for 2 subs or having 1 amp for both subs that match the sub wattage?

My buddy recently purchased a set of Adire Koda Components. The woofer is going to be placed in the stock door locations. We are just wondering about the tweeter placement. The stock tweeter location is on top of the dash reflecting off the windshield. I know the Kodas work good off axis so I figured the windshield could work well. Any objections or suggestions?

going to be doing an install in the gf's 05 grand am and she wants to go pretty big. 2000-4000 watts for the subs and a 500> on the highs. i know the stock 105 amp alt isnt going to be good enough for all this. what are some of the things i need to look for when shoping around. any help would be a great help as i hope to start piecing stuff together soon.....

A little fun with my new recones. Thier strapped at 2ohms and drink up everything I got. Good sign. :bigclap:

How do you wire the amp to a 4ohm load for the speakers.With 2 small tweeters also. http://mobile-emotions.stores.yahoo.net/bosrt6x9cars.html http://www.cardomain.com/item/CLAAPX2120?r...m_term=apx-2120

ok so i've went thru 3 box designs and im just not happy. sub- rf power hx2 15 dual 2 amp- saz1500 @1 ohm gain bout half way h/u- pioneer deh-680mp stock electrical for now 76' caprice so i wanna get the most outta my sub as i can in the trunk. i mean loudest, movin air, flexing shit (1&2 were in backseat) first box was 4cu ft @30...too low 2nd was same box retuned to 40hz....to high 3rd little over 4cu @ 33hzin trunk....great freq response i mean its louder then most people i pull up next to. but i think the sub can do more what really pisses me off is my uncle has my kicker l7 8" on a 4ch usamp cant remember what model. like 900w rms is what he said i think . but i…

I'm not sure.....and um...i used a jigsaw so there a some minor gaps ..what type of silicon do i use..thanks..

Is there anything special to put behind the subs when you drop it into the enclosure so air does not leak between the sub and the front face they are resting in?

My insurance is covering my truck and a tiny bit extra, so with the next vehicle, since I know it'll kill me if I don't ask, which is more audio friendly? (since the price differences on them locally are pretty much negligible, they all fall around $2500-3k) Jeep Grand Cherokee (1995-2003) Explorer Sport (1995-2003) or even another Blazer/Jimmy/Bravada (1996-2004) I'm only really picky about having 4x4; everything else, kinda blurs together to me. *The trucks i'm comparing are the ones that were left on the list after accounting for mechanical issues being taken care of; so no, I got my priorities in order
