Massive Noise Heard Through Subs.

[Guest]

Friends system consists of a Jensen DVD Player headunit, Memphis amp (i think the 1100D), and 2 Kenwood subs. When he starts his car, you hear his engine really loudly through the subs.

I was thinking it was just a bad ground, what could be the real problem?

edit: oh, and his amp makes a small whine noise too when you put your ear close to it

needs a cheap noise filter on there , can be had at walmart, and to double check the grounds , make sure its bare metal ect. i personaly dont buy into the rca on the same side as the power bit, since all my rca and power wires are ontop eachother and i have no problem

re ground it,

try a new set of RCA's

are the power and RCA's on different side of the car? and is it a chevrolet or GMC???

yes check all the grounds H/U, amp..... and if the amp is making noise pull it and make sure its not chassis grounded anywhere

edit: make sure the amp isnt touching any bare metal is what I mean....

its an early 90's Honda Accord. He had this "guy" install his system for him. I told him he could pay me an honest $20-30 to scout out and fix the problem. I told him it could've been a sh*t grounding.

If the amp itself, like a footing or something was touching metal, how would that matter...?

edit: oh, and when you open the seat divider for the rear seats, the amp is like right there lol, so i would need to take the sub box out and find where the hell the amp is behind it.
