Recently picked up a 1990 RX7 and the guy before me did had a system installed but when he sold it to me took half of it out. What I have so far is:
Sony Xplode CDX-GT520 Head Unit
Pioneer GM 6300f Amp
Refrence Speakers 4.
The good thing is it's all already installed with a space for one more amp to power 2 Subs that i need to get in the back. So I'm wondering what should i get to complete my system in the best bang for buck price range? Thanks!
