Pioneer's GM-D8604 4-channel amplifier can send 100 watts RMS to each of your front and rear speakers, for powerful music that'll get you and your car rockin'. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a compact chassis that fits in a lot of out-of-the-way spaces. If you're building a big system in stages, you can use this versatile amp at first to drive a pair of speakers with the front two channels while bridging the rear channels together to power a subwoofer with up to 300 watts RMS. Later on, you can get Pioneer's big mono amp to drive your subs, and switch this amp over to run all four of your full-range speakers.
