ok boys,Need your input since me gonna change my ancient sound system of my yellow e36. Current system is the standard head unit, with 10-disc changer in the boot (which went kaput when the mech re-tinted my car- mother f#$%% spray so much water on the rear window that it shorted my Changer). That was the last straw since the rear speaker also cracking when I play some music loud. The front door speaker no need to tell since almost some weird hissing only coming out.So I need within a budget of 2k, to pimp my sound system. I need the following, and I want you guys to recommend what to get :-a) New head unit - preferably something that can also accept USB connectionb) Maybe 6-disc or 10-disc changer if can fit into budget.c) 2 rear kick-ass speakersd) 2 front door speakerse) 2 tweeters f) i got lot of space in the boot, so subwoofer also can taruk in.g) power amplifiersh) all sorts of wiring so that my battery dont die halfway!Please help!
