A compact amp with plenty of power

Bazooka's compact MA475D marine amplifier provides high-efficiency Class-D power for your marine audio system. This amp is engineered to meet tough marine-grade protection standards, so you won't have to worry about salt and spray damaging your speakers while you're blasting around on the lake or cruising out into the Gulf for a long day of fishing.

Bazooka MA475D 75W x 4 Marine Amplifier

This sleek Class D marine amp offers a low profile for easy installation.

Plenty of sound, plus room to grow

The MA475D 4-channel amp delivers the power you need to drive two pairs of full-range speakers in your boat, sending 80 watts continuous power to each speaker. You can also bridge the amp to 2-channel mode to send 225 watts each to a pair of subs. This rugged amp features both high-pass and low-pass filters, so you can adjust the output to suit your system.

Bazooka's designers know what boaters want from an amplifier, so they designed this amp to be compact, cool, efficient and powerful. You can mount the MA475D in a storage locker, console, or other tight spot without sacrificing space you'd rather use for extra lines, life jackets, and other boating gear.

Crutchfield Customer Review (What's this?)

I was searching for a marine grade amp to power two coaxial kicker 8" in my boat. Being in a boat I wanted to be concervative on power usage, I believe this class D amp will do well. I recently installed but from what I've seen so far this is going to be a great application.

Pros: Flexible with application. Easy to mount, compact, can be used with 4 speakers or bridged to 3 or just two.

Crutchfield Customer Review (What's this?)

Excellent product and expert installation and product selection advice from the pros at Crutchfield!

Pros: Clean power that is easy to install - livened up my boat system and changed the clarity, crispness and soundstage. I added it to the system I bought last summer from Crutchfield - can't believe the difference!

A single voice coil 4 Ohn subwoofer, yes. You can provide up to 225 watts RMS to the sub when you bridge two of the channels to power it. I hope that helps! [ Ryan  Dec 23, 2015 ]  Staff
