Ok guys any help is greatly appreciated here. I bought MR HARLEYS Jl subs and his rockford fosgate amp. I have everything hooked up but for some reason..i get no sound from the subwoofers at all. When i try to change songs on my HU i get an odd sound and the deck dims a little bit. I'm having trouble giving more information so ask any questions and ill answer them to the best of my ability. Thanks A LOT!!!!
