Pioneer GM-D1004 Compact Class D 4-Channel 400W Bridgeable Car Amplifier

Double the power, double the fun

Pioneer's GM-D1004 4-channel amplifier will power your front and rear speakers with 45 watts RMS each — that's almost three times the power of a typical factory radio or aftermarket receiver. Even better, this compact amplifier runs so efficiently that it can often get its power from the same circuit as your receiver, saving you some wiring hassles. And its tiny size means you can install it almost anywhere, even behind the dash in many vehicles.

You can bridge a couple of the GM-D1004's channels together and drive a subwoofer with 90 watts while still powering a pair of front speakers. Universal harnesses let you get signal from an aftermarket receiver's RCA outputs or a factory radio's speaker wiring.

Important note: If your car receiver's power circuit is protected by a 15-amp or larger fuse (check your fuse box or owner's manual), you can tap into it to power your GM-D1004. Otherwise, you'll have to run a power wire to the battery. Be sure to add a 15-amp inline fuse as close to the battery as possible.
