ok I just changed out my speakers. In the back I have the Pioneer TS A6870R, 3 way, 220w max, 4 ohm In the doors I put Infinity Reference 6012i, 2 way, 180w Max, 4 ohm They sound good, but I have been debating on my next move. I want to replace the head unit, but I figure a amp would be a much better first move. So now the questions. Is an amp a better move? What kind of amp am I looking for? How should/if I rewire the speakers? PEACE Also, if any of you ave amps that may work for my situation, I'm looking to buy.
