Blaupunkt's Plug'N'Play Series amplifiers produce big power from ultra-compact housings, so they'll fit into some tight places in your vehicle. These full-range Class D amps use miniaturized power transformers for cool, efficient operation so your speakers will sound fuller, with clearer highs, richer mids and more powerful bass. The THA475 4-channel amp pushes out 75 watts RMS per channel to four speakers, or can be bridged to drive 180 watts RMS to a pair of subwoofers or speakers. A direct auxiliary input lets you plug in your MP3 player or navigation device, a big plus if your factory receiver has no aux input. An automatic input detection circuit eliminates the need for a remote turn-on lead.
