Hi, I am relatively new to car audio but I recently upgraded all the speakers in my Eighty Eight Oldsmobile. I have had a Pioneer deck for a couple years but I wanted better sound quality. In doing so I am considering buying an amp. (As a side note I buy a lot on Ebay) I found a Boss 4 channel amp 2000 watts. The speakers that I have in my car are 2 1200 watt(600RMS) and 2 600 watt(300RMS) Before I do any purchasing I want to make sure that I would hear a difference. The stereo is 50x4. Does that seem like a good purchase? Would it make a difference? Oh the amp is 105$. Thanks.
