Pioneer GM-DX104 4-Channel Class D Bridgeable Compact Hi-Res Car Amplifier 45 watts RMS x 4 400W Max

Sound improvement that fits

There's more to great sound than just ear-splitting volume. Pioneer's GM-DX104 compact high-resolution amplifier delivers realistic sound and a big soundstage from a tiny 4-channel amplifier that runs so cool and efficiently it can be installed behind the dash or under a seat. Pioneer's Total Vibration Control design uses a rigid chassis and weight-balanced component placement on the main circuit board to counteract and dampen any vibrations that could cause distortion to the signal or damage to the amp.

Power and resolution

The GM-DX104 will power four front and rear speakers with 45 watts RMS each — over twice the power of a typical factory radio — so you'll hear your music clearly while you're on the road. You can set up the amp in 2-channel mode, bridging front and rear channels together, and drive two speakers with 90 watts each for a louder front stage stereo system. The amplifier's wide frequency response and Hi-Res Audio certification guarantee you'll experience all the finer nuances of your favorite music.
