Crossfire VR404 Car Amp

Pros: Sound quality, volume, everything else.
Cons: NONE

Really good sound in my car. I have all retail speakers and this amp makes them sound amazing! I would bye this amp if you just looking to improve your cars sound.

Pros: Seriously underrated @50x4. Extremely clear. Built in crossover.
Cons: larger than most 50x4. Pricey.

I just had one installed. This is supposed to be an amp for highs. I can tell you it will push the hell out of some subs. Bridged 2x200 @ 4 ohm or 4x50 @ 4ohm. I have 2 channels pushing 6 front speakers and 2 channels bridged pushing one 10" polk MM10 (500W RMS supposedly). I have the gain less than 30% and the stereo POUNDS!. I'm no bass head but, it seems to push that sub HARD. I have had it damn loud, much louder than you can stand being in the car, and it's still clean! The last car stereo I had included a 200W linear power pushing highs & 380W (modded) linear power pushing a pair of isoberic orion 10s. This amp is making more power than the pair of those. That polk hits harder (if not deeper) than the pair of orion 10s.
