About the Blaupunkt EMA 455
Blaupunkt will power your music
Blaupunkt will power your music
Blaupunkt's EMA 455 4-channel amplifier will power your front and rear car speakers with 55 watts RMS each — plenty enough to give you the extra clarity and impact you want for your music. Selectable high-pass filters let you clean up the sound even more, by removing the extreme low rumble from your full-range speakers, great if you're using a subwoofer.
Bridged to 2-channel mode, the EMA 455 can run two high-performance speakers or subwoofers with up to 165 watts each. Variable low-pass filters give you extra control over your sub, and a bass boost lets you bump up your punch a couple of notches when you need it.
A heavy aluminum heatsink helps keep this compact amp running cool and reliably. Speaker-level inputs let you connect it to a factory radio with no RCA outputs, so you won't need a line output converter or other device in order to play music.

I installed this in my Yukon to replace the factory amp which had gone bad. I put my back two door speakers which are 61/2" kenwoods to 2 channels and bridged the other 2 channels to run a Rockford fosgate 8" 4ohm sub. The clarity and sound is very clear. Im very happy with my purchase..
