...next? tips for prices/brands. Thanks? Already have two 10-inch pioneer subwoofers in audio box already. I have a 94 Chevy blazer. The stock spearkers are pretty loud as it is. I want new stereo with auxilary plugin, and possible more speakers. I know Ill need amps and what not but I am a virgin to this whole thing. Im not trying to go ALL out I just want to give my car system a little upgrade. What prices am I looking at. And what brands/equipment do you reccomend or do I need. Total amount what would be a good deal. thanks in advance
