ok so i was looking at the factory amp and was wondering how i would go about hooking up an after market amp. how would i wire it up ( rca's remote blah blah)

 

Last week I did a 2004 RSX factory sub re-wiring from a stolen recovery, the autobody shop went and ordered the wrong factory amp replacement and the customer ended up with the factory amp without the sub out plug. In that car, the sub runs at 2ohms, so check at least one front and one rear to make sure that your speakers are not 2 ohms as well. Otherwise the amps you buy will have to be 2ohms stable OR you change all of your speakers out. Croos your fingers and hope they are four to ten ohms instead. The car I worked on did sound pretty sweet (for being a factory deck) after the sub was back on.
After you sort that out just run everything like you would with a normal amp install except use the Hi-low level adaptor behind your deck just like the one MrEastside showed you on the 3rd post to this thread. For remote tap into your ACC for your 12V power or if your very talented you might be able to find the trigger in your amp wiring harness under the seat, but you'd have to leave that factory amp powered up as well, just to provide the trigger.
