Pioneer

It takes a lot of amplifier power for your music to be heard clearly over the sounds of the waves, wind, and engine noise. Pioneer's ME-Series GM-ME400X4 four-channel marine amplifier can put out 75 watts RMS per channel, enough for everyone in and around your boat to hear the music. You could also use this amp in 2-channel bridged mode to power a couple of subs with up to 300 watts RMS each. This amplifier's output power matches up perfectly with Pioneer's ME-Series TS-ME650FS and TS-ME650FC marine speakers, which are each rated for 75 watts RMS. The amp features high- and low-pass filters to tune its output for your speakers and subs, and make them sound good. Conformal-coated circuit boards and rubber connection/control covers keep water and dirt away from sensitive areas.
