Well can you name some brands that sound better? I would love to hear them, if i haven't already. If you could buy a JL amplifier, the slash series at 500 watts rms for 400 new, would you? And if your companies are so much better then why do professional audio shops not sell those brands to get more satisfied customers? I think there is a reason they predominately stick to Alpine, JL, and Hertz. Not trying to be rude, but just really want to figure this out, and am throwing my points at you so you can give a suggestion to as of why things are such. I have heard all my friends system and believe me, i want out of their cars.
