Ok, I want to put 2 Comp 12" subs in my 90 mustang gt that are rated 150 rms/300 peak. i was gonna power these 2 subs with a alpine mrp-m350 which is rated 350 rms at 2 ohms. I was then gonna buy 2 6x9, dont know which yet, and power them with either a small 2 channel or mono amp. i want the 6x9 speakers to be about 50 watt rms or less and these will be put into a sealed box. The head unit ( clarion DXZ545MP) will be powering the other 4 factory speakers in the car. Will this sound good and which 6x9 speakers would you recommend and which amp to power them, 100-200 dollars is what im willing to spend on the 6x9 and the amp. thanx
