Nothing personal but the wanting to hear it outside the car is just plain annoying. I have a wall of 2 18s in my Grand Prix running off of 7415 watts clamped real world power and you can barely hear it outside the car other than the windows shaking. I have layers on layers of deadener.

I understand you want people to hear it, but all that does is put a giant come steal me label on your car. It's personal preference tho.
