Infinity Primus 6004a Compact 4-channel car amplifier — 60 watts RMS x 4

Product details

Add power

If you want to improve the sound in your vehicle without emptying your bank account, Infinity's Primus 6004a 4-channel amplifier may be just what you're looking for. This little powerhouse will send 60 watts RMS to each of your front and rear speakers, adding the detail and punch that a car stereo just can't muster. Or, you could power your front pair of speakers with the front two channels, then power a subwoofer with up to 140 watts RMS from the rear channels in bridged mode.

Works in almost any vehicle

Speaker-level inputs allow this amplifier to work with almost any system, which is handy if you're keeping your factory radio. Separate high- and low-pass filters help the amp do its job, whether it's driving speakers or a subwoofer. You can use the built-in bass boost to add more low-frequency fun.
