solved Matthew, I know exactly what it is -- I will need to replace four resistors in the amp. A few amps were made with the wrong value resistors in the input section power supply regulation circuit. I just recently found out about this when I got a couple others back. It passes on our test bench as it runs 15v but at a bit lower voltage in a car it makes that sound. What is your address ? I'll send you a tag to send it in. - Jacob

is there a way i could increase the voltage on the remote line from 11.3 to the recommended 13.8 to see if that helps. im not really sure how i would go about that if its a simple hardware store item or what not. im hoping thats the issue and not the amp itself

ive tried different head units, sources, and speakers all having the same problem. ive basically isolated the problem to the amplifier so im waiting to hear from sundown now to see if its something fixable (ground, or low voltage on the remote line) or if it needs to be RMA'd.

the headunit is grounded thru the harness which ive never had any trouble with and ive had it for 3 years now. the amp is grounded to the floor by the seat belt bolt under the back seat. the sound is like a garbled sloppy distorted sound other than that i couldnt describe it, however the music is still audible. before i had a mono sub amp and it worked perfectly but this is all new wiring for this amp. i would like to try another amp however i dont have one at my disposal so i cant really do that. i did try multiple input sources and all of them had the same problem.(2 decks and an ipod with an rca attachment)

so i just installed my new sundown 100.4 amp and i have a terrible distortion problem even at a barely audible level. ive double checked all the wiring for proper polarity and checked that i have a good ground connection too. ive also tried speakers which i know are good as well as inputs that i know are good. the only inconsistency ive found is the the remote from my deck puts out 11.3v and the book that came with my amp is asking for 13.8v would this cause the distortion or is there something wrong with the amplifier. thanks for the input

well my budget is $1500 or less including dynamat for the whole car. and I'm mostly concerned with sound quality because I listen to a large variety of music, but it does have to bump pretty hard too. I'm open to any suggestions as far as other amps and speakers go, especially if your familiar with what Ive been looking at and can compare them to what else you've heard. Thanks again for all the input, Matt

Awesom, thanks for the input. Now would i need both batteries or would i be able to get by with replacing the original battery with something like the kinetik 2400. I say this because i bought the car as a sports car and i often drive it like one. I plan on removing the rear seat assembly for this install and using a custom fiberglass enclosure or a simple mdf setup to try and keep the weight close to what it is now. Also i don't plan on upgrading in the future, i believe this will be more than loud enough to keep me happy.

I have a 2003 mustang and I'm planning on buying an 12" Fi Q with the BP power option, a RF T1500-1, and a RF T600-4 to power the four corners. My car is 100% stock and i was wondering if my 105 Amp alternator and the big 3 fix would be enough to power all this. If not what should I do. Oh and why is it people prefer batteries to capacitors? Thanks, Matt *Edit* The alternator is 105-110 Amps. Not that it makes much of a difference...
