Plays loud and clear

Many people never think to upgrade their car's audio system, suffering with subpar sound when they listen to music. Pioneer's GM-A6604 4-channel amplifier will greatly improve the sound quality in your vehicle, so you'll look forward to spending time on the road. This punchy Pioneer amp will power your front and rear speakers with 60 watts RMS each, which is a huge jump over the power supplied by your car radio. You'll hear more of the little details in your music, even when you turn your system up to compete with the road noise.
