Ok, first of all I am not a car audio know it all, My stereo consists of a alpine cda 7941 HU, mb quarts dkd 5x7 door speakers , 2 12" w6's JL, and sony explode 600w x 4, and a orion xtr2400 sub amp. my question is that my HU has a sub pre out, the rca's that are connected to the sub pre out go to the sub amp in put. The problem is that the subs have words coming out of them. The installer was in rush last night to get home and I think he may have hooked something up wrong. I dont knowmuch but i think if there is a sub pre out , that should be able to give the sub amp signal with no high frequency??
if someone can help me out i would appreciate it. thanks..
