My buddy has a Rockford Fosgate P4004 amp that he wants to get rid of. It's out of his Volvo but obviously it can go in a Miata too, and it's a real nice amp, he had it powering 2 12 inch Kicker Comp subs, it bumped pretty good. Its not super powerful and I feel like it would be a decent sized amp for a Miata. It's a 400 watt 4 channel amp. 50 watts per channel, you could run your door speakers off of it if you wanted, if you have 2 door speakers, some tweeters and some headrest speakers or whatever or if you have a sub or 2 it will run those nicely too. Asking price is $160 obo, make me an offer



I also have all the wiring to hook it up in your car and since it's out of a volvo there is more than enough wire to set it up in a Miata no matter what. The only way you would run out of wire is if you mounted the amp in the front bumper lol and even then there would probably be enough. Amp and wires is $200 obo

 

I also have an almost full roll of 16 gauge speaker wire that I can include if you want it

 

Bump. Make me an offer
