mmn... i know an amp would make it sound much better, but its jus extra hassle n expense, had a sub in my old car aswell but to be honest cant be arsed to give up boot space n trail even more wires under the sills jus for a bit of extra bass... ive already got some infinty 6.5" coaxials... think i jus gunna see how they sound un-amped with a new head unit before considering an amp... like i sed before i ent really interested in a massive sound system anymore... just want it to sound a bit better than the factory equipment (which although it gets slated alot, sounds better than any other OE system in other cars ive owned)
