Wow... thanks for all the replies guys (and girl)!
Just to clear up some of the confusion - I already have the head unit. It's running in my truck now, just with the stock speakers. I think the HU is rated at 40x4... but I don't think that'd matter anyways, right? Wouldn't I be using the pre-amp outs?
I was definitely thinking Bostons or maybe MB Quart speakers. Not really sure on amps. I know DanO and Davey both like PPI stuff, but I think they're a little out of my price range.
As for what kind of music I listen to - really, a little bit of everything. From harder rock (Papa Roach, Linkin Park, a lot of old Incubus, etc) to more mellow stuff (newer Incubus, Dave Matthews Band, etc.) I'd prefer to build the system to sound good with Dave Matthews (since it seems like that style of music shows off system clarity better than a bunch of muddy electric guitars.) I'm looking for crispness and clarity. I want a sub with tight bass... not sloppy (since I don't listen to any hard-bass techno music.)
Labdog - you installed separate tweeters on your A-pillar? I was thinking of doing the same... the Bose in my demo has them.
Ducman - That's not a bad idea (just get speakers first.) If I can get away with no sub at all... that's fine with me. I'm not sure if the Bose system has a sub or not. Do you think the 40w head unit will be enough to drive a set of Bostons or MBQ's, or will I need an amp? I'm gonna try to do this on as little $$ as possible, as every dollar I spend is one less for the racing budget next year
Anna - what do you want for those amps?
Everybody else - will the amps Anna has be sufficient for what I want to do?
Thanks again guys, I appreciate it.
