Rockford Fosgate Mini 400W 4 Channel Amplifier

Rockford Fosgate took their mini 4 channel amplifier and made it better with the Punch Boosted Rail, 400 watt, 4 channel amplifier. With the success of the mini, 300 watt amp, Rockford decided to step it up and give it some additional features and more power.

Bridgeable and 2 Ohm Stable

This mini amp is now bridgeable and two ohm stable whereas the older, 300 watt version was not.

Super Compact Chassis with Plenty of Power

This amplifier is super small, measuring only 6.75" x 4.25" x 1.53". This amp is rated at 50 watts x 4 at 4 ohms, but like all Rockford amps, it will actually put out more power than that and they send you the paperwork that shows what it was tested at.

Low Current Draw Ideal for Classic Cars, Powersports, and Hybrid Vehicles

One of the added benefits of the Rockford mini amps is the low current draw. These amps were originally designed for powersports and hybrid vehicle applications where the charging systems are not like those of new cars. Many classic cars have been upgrading or modified over the years, but this amp works fantastic as it does not put too much strain, even if you are running an old generator.
