I'd like to resurrect this thread

I have a stupid whine in my system as well. I went through all the wiring and all the wires running to the amp are correct and not damaged. Tell me about this noise filter and where u got it? I too have a low grade hu it's a okou I bought for $140 it's a 7 inch DVD/CD/ipod/Bluetooth knockoff ...I thought I'd give it a try since a comparable hu would be over $800! If it's the deck is there a way to find out? I'd really like to try this noise filter thing.

So what your saying is that your head unit has a dedicated subwoofer output on the back, but it is a single rca connector. i assume you have your amp bridged with a single sub aswell. you should get a splitter and connect it. it will cut down the gain voltage coming from the head unit, but you should still notice a substantial gain from the sub if your head unit has a subwoofer level control. if not, then it will be roughly the same only not crossed over by the head unit again this assumes you have bridged your amp to a single sub.

Apply dirt liberally, rinse and repeat

It sounds to me like something isn't properly shielded. If the new wiring going to the components is cheap wire then they'd be susceptible to picking up electro magnetic interference from other high output devices. So the permanent solution would be to make sure all of the wiring is the proper rating... but baring that I think something like this is what they were talking about as far as a noise filter goes: Electrotronics

Good luck!

my door speaker wire is 14 gauge wire and the subwoofers have 12 gauge from cadence.. I think the wire is up to par i ran the 0 gauge amp power wire down the driver side and the blue amp wire down the passenger to avoid the buzzing and still ended up with it...I think ill try this noise filter you attatched...i thought it was just wired in the hu red power wire..I take it the blue and black wire to the ground and amp turn on wire?
