Pioneer GM-D1004 4-Channel Car Amplifier

Pioneer GM-D1004 4-Channel Car Amplifier

The Pioneer 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 Pioneer 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.

Compact Design

Whether you call it “compact” or “micro” the Pioneer GM-D1004 will wear the name proudly. With the size equivalent to slightly smaller than a standard red brick, you’ll have no problem finding a place to mount it or conceal it behind our short chassis Digital Media Receivers stereos, glove box or even in the center console. 

Small But Powerful

It may be small but don’t let the size fool you. The Pioneer GM-D1004 is capable of delivering up to 400 Watts of maximum output and is more than comfortable providing 45 Watts of power per channel, that’s more than enough to improve the performance of your factory or aftermarket speakers.

Varity of Installs

Today more and more music lovers are taking their music off-road and finding ways to enjoy their music recreationally. With the GM-D1004 you can add great sound to your motorcycle, ATV, or boat where a conventional size amplifier may not fit. 

Flexible Connectivity

For DIYers, the Pioneer GM-D1004 amplifier is not only small and powerful but it’s easy to install. Simply connect power and ground at the radio and get more installation flexibility using hi-level or low-level inputs with a signal sensing remote turn on so you can use it in combination with a factory or aftermarket head unit.

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.

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.
