Hey guys, I have a 90HP punto and i love the car very much. Since the stock speakers were so crappy, i had them replaced with Polk audio components in the front and Lightening audio components in the rear. Both 6.5". The sound has improved quite a bit, but i still dont feel the bass the way i get from my endeavour which has a similar setup, but with a JVC head Unit. Now I think the Head Unit is holding back these speakers, and im wondering if i should get a new HU or an amplifier or both. I would prefer to get a new HU because i am hearing a lot about needing a separate on/off switch for the amplifier, but is there any that is compatible with the steering controls? Also, most importantly, can someone recommend a guy for fitting said amplifier, head unit?
