Replace Factory Amp

[02bugg]

Ok searched and searched and didnt find anything.

Im attempting to remove and replace my factory amp in my 02. Ive located and removed it, but my amp that im replacing it with has positive and negative for each speaker. Thats ok but the factory amp uses one connector with only positive wires.

Now my question is how would i go about re wiring all of that?

any help would be appreciated

Uhh.. what? There is no "factory amp", unless you're talking about the built in amp in the head unit, or the built in amp in the factory sub.

All speakers take negative and positive wires to work (that I know of), so it's not possible that an amp is manufactured with only positive outputs.

If its under the passenger seat its the factory sub.

exactly the one under the seat, i think it was a built in sub but its a amp none the less, atleast that is what subaru calls it atleast

See this post:
NASIOC - View Single Post - Stock head unit information -- pin-outs, aux inputs, and more

and if further questions refer to that entire thread.

So you're removing the factory sub and replacing it with an after market amp and sub? Or are you installing an additional amp for the door speakers, or what? Either way it's not necessary to remove the factory sub.


Are you using the stock head unit, or aftermarket? If stock, are you planning on running a line level converter to the amp, or running speaker level wires directly to the amp?




I'm confused..

Yeah its a built in amp for only the subwoofer. The stock speakers are powered off of the factory stereo head unit.

What are you trying to accomplish?

I'm not understanding what's being replaced and why? If the factory sub/amp combo is being removed, what is replacing it and what is it powering?

If you are putting an aftermarket amp are you attempting to power the interior door speakers? If so then you don't need to remove the factory sub since the the door speakers are being powered by the head unit.

If you rare replacing it with an aftermarket subwoofer then again it doesn't need to be removed or rewired. A new aftermarket amp will need to be installed to power anything of any real use.

Please explain your idea or intentions a little clearer so we can attempt to help.
