800 Watts 4-Channel Amplifier


The Jensen Power 400x4 Multi Channel Car Amplifier with 800 Watt Peak Performance
is a force to be reckoned with. Your multi channel car amplifier allows you to connect all of your car speakers or
subwoofers giving you optimal sound performance when you need it the most. We anticipated continuous use of
your amplifier so we engineered a High Current & Efficient MOSFET design that enables you to have
insurmountable power. Your multi channel speaker/subwoofer amplifier delivers up to 800 Watts of Peak Power, 250
Watt RMS via 2 Channels at 4 Ohm Impedance, 75 Watt RMS via 4 Channel at 4 Ohm Impedance and 100 Watt RMS via 4
Channel at 2 Ohm Impedance.

Your multi channel car amplifier is optimized with a Class AB design that significantly reduces distortion and
minimizes idle current for streamlined studio sound quality. We cannot stress safety enough here at Jensen so we
designed a built in short circuit protection via a thermal and DC offset safety protection for your amplifier. The
journey will never be the same without Jensen.
