Bored with the way your music sounds in your car? Sony's XM-GS6DSP 6-channel amplifier can make your audio system sound great, sending 45 watts RMS to each of the front and rear speakers, while delivering up to 600 watts RMS to a sub. This amp can also use its onboard crossover and bandpass filters to power an active 3-way system, driving a pair of tweeters with 45 watts each, two midrange drivers with 45 watts each, plus a couple of low-frequency woofers with 90 watts each.
