I want my Hi'* and mids loud. How do I get it loud and what are some amps to do this with?

yes if u have aftermarket speakers then that would be a good idea. how many watts aret they and what brand are they

Right now I have a 600watt Power Acoustic and I am running my factory speakers.

I'd get some nice 3 or 4 way 6x9'* at least to start. I've heard some Kenwood 6969ie and their mids are very nice and the high'* scream. Not that you have to go with those, but decent 4 way speakers will be a nice start.

So is trhe amp that I have good enough? I did think about buying a capacitor for the highs and the bass. I want all power and crystal clear loud sound.

Eclipse makes good component amps and components themselves. Very good quality. You should look into Eclipse you won't be sorry.

i'd ditch ur amp now and get a nice 4 channel amp. anywhere from 50x4 to 75x4 would be plenty. Xtant, Alpine, RF, PPI, etc would be a decent selection in amps

it would be best in my opinion to get better speakers start out with upgrading the front ones so u can have mor flexibility when u decide to get subs

I just bought this yesterday. 600watt 4ch. I guess you say its no good , huh?

ohh my bad..i assumed it was a 600 watt 2 channel amp

don't know much about power acoustik
