Our take on the MTX TM452

by Jon Paulette

Compact, powerful and built for boating

MTX's TM452 marine amplifier doesn't take up a lot of space on your boat, but it does deliver the power you need to rock the dock. This 2-channel amp delivers 75 watts RMS per channel at 2 ohms, or 45 watts per channel at 4 ohms, and its compact size means you can install it in a small storage locker or other tight spot in your boat.

Great for a variety of applications

You can use this 2-channel amp for a variety of applications. It'll power up a pair of high-performance coaxial or component speakers, or you can bridge the amp to a single channel to drive a sub. You can run the built-in frequency filters in high- or low-pass mode, depending on whether you're powering speakers or subs.

Like the rest of the MTX Thunder marine line, the TM601D meets tough UV and salt/fog protection standards, so you won't have to worry about your equipment while you're blasting across a lake or cruising out to your favorite fishing spot. A special coating helps prevent corrosion on the circuit board, and the amp's designed to disperse heat efficiently so it won't overheat . Sealed covers keep the controls and speaker terminals dry, so you'll be able to enjoy great sound for seasons to come. And MTX protects this amp with their unique 5-year warranty.
