Upgrade your in-car listening experience with a Pioneer GM Series amplifier — it'll provide the power and sound quality you're looking for, all in a reliable package you can count on. Under the hood, solid construction eliminates resonant vibrations that can cause distortion, while an efficient cooling system keeps the amp running clean when it's working hard.

The GM-5400T 2-channel amplifier produces 125 watts RMS per channel — just the ticket for powering a set of high-end component speakers. Or bridge the amp to mono operation for a potent 380 watts of power on tap — plenty of power for laying down some serious funk with a sub or two. Activate the built-in low-pass filter to send your sub everything below 80 Hz, while high- and low-level inputs allow you to add the GM-5400T to almost any system, even a factory stereo.
