Let me start from the begining I had installed on my cadillac seville a sony exploid stereo with two 12" JL audio sub powered by a 4 channels rockford fosgate 600w amplifier and the sound was decent and really clear, but I just bought my Jensen vm9311 DVD player and a new 2 channels hitronic (1200watts) amp for my other speakers, well what I was trying to do was switching those amps and use the hitronic with my subwoofer and the rockford fosgate for the rest of the speakers now it sounds way louder but the problem is that I can heard like an engine noise in my front speakers did i did something wrong? please somebody help me!!
