How do I adjust the balance on a JL Audio 300/4 amp?  I know I am supposed
to play with the input sensitivity but how do I know how much and which way
to put it?
Also I get a bit of hissing at higher volumes.  Should I increase the volume

Wondering what size speakers/config I have in my Integra GSR. I have
tweeters separately near the mirrors and woofers below. Think I have
separates/components up front and co-axial in the rear all 6.5" round.
Also, I found out that my woofers/mid bass in front have been stolen so

This used to get posted once a month and since it's been a little slow around here lately,  I thought it would be a good idea to post it.  Please note, in the interest of saving space, I left out the section on competition (Section 6) as there does not seem to be much interest in ...

I have a Mazda 2000 Protege with a 4M32 head unit and a tape deck.
After working intermittently for some time, the radio/head unit just
went blank and stopped working.
I have both units out of the car and am trying to find the fault. A

6-1/2" Car Speakers
in my 1997 Saturn SL1 with a new Sony cd/mp3 head unit with front AV
input. Unfortunately, I did not notice hardly any change in the bass of

OK, if you'll look back to the (pathetic) "Premier DEH-P880PRS VS  ????"
thread, you'll see that I'm looking into a new, higher end HU for my
re-entry into SQ oriented car audio.  So, in the absence of response to
that thread, I offer the opportunity for open bragging, taunting,

After researching and listening to a lot of amps out on the market
today I feel kind of let down on most of the offerings. Last year i
picked up an a/d/s PQ20 that i was quite pleased with and set aside
for when i bought a new car. Well....that time has come.

it 2 days ago and now its not working, does anybody else have this

I've recently purchased one of those JVC KDDB711 stereos and have run a
cable from the 2 line in ports atthe bck to my MP3 player (I-river).
This works, but the only amplification I get it from the i-river which

I'm a new Ipod user and am working through the process of setting up my car

I have a 2005 Scion XB with one 12" Rockford Fosgate P2 in the back. I
have a P3002 running it but I need to know what I need for speakers.
I like the diamond audio d6 6 1/2 and 5 1/4. I don't know what amp to
run. Do I need a 2,4,5, or 6 channel amp?

I've just bought a 2nd hand Blaupunkt stereo (a London RDM 104) which
even includes the fitting instructions (a 1st for me). Said
instructions say DO NOT use the positive/negative system comnnectors in
the vehicle.

I am trying to design an enclosure that will fit in the back of my
vehicle, and it seems I am left with only one option that will
accomodate box volume, port length, and basket depth. The issue I am
having with this design is that the port will exit the enclosure in a
