Polk's PA D5000.5 5-channel amplifier may be small, but it can power your complete system, sending 70 watts RMS to each of your front and rear speakers and up to 500 watts RMS to a sub. Or, you can switch this little beast to 3-channel mode to drive a couple high-level components with 200 watts RMS each and still have that 500 watts RMS left over for the bass. Best of all, this powerhouse will fit in almost any location in your vehicle because of its convenient size and shape.

Polk's Class D amp technology helps this amp reproduce music very cleanly, with no added coloration or distortion. Adjustable high- and low-pass filters help you to tune your system, keeping bass away from full-range speakers and high notes away from subs.You'll find that the subsonic filter's a big help for tuning your sub in a ported enclosure. Polk includes a wired remote, so you can control the subwoofer level from your front seat. This amp's tough, good-looking stainless steel case won't tarnish, even in very humid conditions.
