I have a 1997 Mitsuubishi Eclipse GS-T Spyder. My dad, boyfriend and I took out my backseats (afterall - they suck...) and took my dad's system out; which contained: 4 10" subs (DB+ by Kenwood) and stuck it in the place of the back seats. We also got some plywood and cut out 4 extra spots. In the 4 spots I have 2 Sony Xplod's 5 and a quarter in diameter (small, but by far the best speakers. I recommend them!) and 2 cheap ass speakers I plan on replacing... At a measurement of 6 X 9. Still have the two Infinity stocks in the back panels, and two shitty speakers in the front that I plan on replacing. Then, mounted on each side of the sub box I have 2 Kenwood 5 channel amps, 1200 watts each. As for the radio, I have a brand new Sony XPlod, which is very good, and only 100 bucks at wal mart! Great way to save money and have a great radio that has an aux plug in. So, with all that said, what speakers should i use to replace the crappy speakers I have? I was thinking either more Sony Xplods or Pioneers. I will post the pics of them up as soon as possible. I know Sony isn't the best of all brands, but I'm going to college and I'm on a budget.
