Pioneer GM-D1004 400 watt Compact 4-channel In Line Head Unit Class FD 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 a 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.

	4-channel amp This amplifier has a large capacity power capacitor that provides steady power and clear and powerful sound, even at loud volumes. It offers no less than 100 Watts x 4 channels in a compact design.
	Input sensor The GM-D1004 automatically detects input signals, and selects an input signal mode between the RCA level and the speaker level. Also, when this amp is connected to a car receiver without RCA inputs using a speaker wire, it turns on simultaneously.
	Total vibration control There are grooves on the bottom of the amplifier’s chassis, which suppress unwanted vibrations caused by driving. Thanks to this total vibration control – or TVC concept – you can also enjoy high-definition audio in your car.
