Sup,

To start off, I'm not by ANY MEANS an electronics newbie. But I'm stumped.

So, here is my question - but dont jump to conclusions at first...
Q: How in the heck do you install a subwoofer amplifier on the stock head unit ?





I have noticed that my 2001 Frontier has a ground looped speaker wiring system (I think, I havent investigated thouroghly though) and am having problems getting an amp to work with my stock head unit.

I even Exploded a crappy Sony-Explode because of this.

See, Im not changing my head unit, or wiring (Which is usually NOT a problem) but what I noticed is that when I am using the HIGH LEVEL unputs of an amp (OR RCA's) it DOES NOT WORK. BUT, these amps work in my other truck. (Ohh yeah, but my point was that with the SONY Explode, the high levels worked. BUT, with a Memphis and a Planet Audio, I am stumped.)

At first, I was confused (and blew an amp) but didnt realized that it was ground looped. (That is usually not the first freakin thing that you check, you know) Then, I bought an amp from a local stereo shop, called him back because it "didnt work", drove up there (Him thinking that I was stupid) tried a new amp, and still couldnt figure it out. Later on that night, I realized on accident that if I ONLY HOOK UP THE (+) SPEAKER WIRE, IT WORKS.

1 wire hookup. Thats f'--'ed aint it ?

So I assume it has a body-fed ground loop. Right ?


Well here is the tricky part. When I try using a line-level converter (11 to 1 converter) [converts high level speaker wires to RCA jack] it wont work at all. I tried 1 wire, both wires, and two amps. Tried using the ground loop brown wires, nothing. And Yes, the line level converter works because I tried it on another truck.

So, anyways, my question is this simple:
How in the heck do you install an amp on the stock head unit ?


Any ideas about the loop ?
