i have a problem that i hope someone can help me answer. My girlfried has a 2001 impala and i put my 2 12" MTX subs in her car with a 250watt MTX amp that i got at Best Buy some years ago in a package deal. Any ways because we wernt going to put an aftermarket cd player in her car i went out and bought a speaker wire to RCA converter. I ran the remote wire to the fuse box in the front and connected it to the windshield wiper fuse. With the wires, at first when i installed it i just connected everything to the left speakers and it worked good. I then wanted to do it correctly so i connected the left speaker wires to the left rca converter wires and the same for the right. When i set it up like this the subs would not bump unless i faded to the right or left but when it was in the middle there was no bass. She also has a stock amp in the trunk so i thought this was causing the issue. So i re hooked it up to the way i previously had it and this time i did it good and i soldered the wires and used shrink wrap and everything to make sure all the connections were good. This worked and the subs would hit and everythings dandy. Now to the problems. My first problem is that for some reason, and i dont know why, the subs will sometimes produce extremly loud feedback even if the radio is down or even off. This is extremely annoying because it will get really really loud and its just a rumbling noise from the subs. The next issue is, is that the battery has died twice already on her car. When the subs are connected sometimes when the rumbling in the subs comes on the lights in the dash flicker and stuff. So i've dissconnceted the power wire from battery and her car runs ok now. I was wondering if anyone had a solution or knew why the subs feedback so bad and why the battery gets drained. Do i need to put the remote wire into a different fuse? or what. I dont know what i need to do. I was thinking of looking into some sort of switch that can kill power to the subs remotely or via a switch so i can have them on when i want to bump and off when im not so it doesnt drain the battery. Any help would be greatly appreciated and sorry for such a long post. Thanks

"subs will sometimes produce extremly loud feedback even if the radio is down or even off." Grounding issue most likely. Make sure the amp ground is touching bare metal and is not going through any paint (sand any point off of the chassis).

As far as the 2nd issue, did u use a DMM to test that fuse? I personally would connect it to the stock radio harnesses relay (should be a red wire) but as long as you tested it to make sure it should properly turn off (which the windshield wipers should be like that). Where in Michigan are u at?
