Looking to upgrade your system's sound? Whether you're ramping up your aftermarket receiver or adding much-needed power to a factory radio, you can count on Pioneer's GM Series amps to deliver what you're looking for — clean power. Power that'll bump up the bass, sharpen the highs, and make your listening experience something you'll look forward to every time you turn the key.

The GM-5500T 2-channel amplifier is well-suited to drive a pair of high-performance coaxial or component speakers, with 125 watts RMS per channel. You can also bridge the output of this versatile amp to punch out 400 watts at 4 ohms, and you'll find a low-pass filter that adapts the amp to driving a subwoofer. Speaker-level inputs allow you to add the GM-5500T to a factory stereo.
