I'm going to help my friend put a new system in the Integra he's buying from me. I'm a bit out of the loop on what products are good right now. We want to build something with good sound quality and decent volume, that will sound good with various types of music. I'm pretty sure we'll go Alpine for the h/u. We need to decide on a compnent set for the front (6.5" 2 way) and subs (will probably go 2 10's, but maybe a single 10 or 12) and either a good 4 channel amp or 2 amps of the same brand. Looking to spend around $100-175 for the component set and possibly a set of matching midbass drivers (for rear fill); $150-225 for subs, and under $375 for amp(s). Sounds like a tight budget, but from looking around on ebay and forums we should still be able to get pretty nice stuff for these prices. Going used on the amps isn't out of the question if it would net much better ones. The goal for this system is basically to see how little we can spend and still get very good sound. Any reccomendation on what brands & models to look into?
