Serious Power. Seriously Compact.
TM400X4ad
The Power Marine TM400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgate’s proprietary Class-AD technology, allowing the amplifier to produce more power with less current draw from the vehicle's charging system.
Featuring Constant Power which results in up to 25% more output power and produces the same output at both 4-Ohm & 2-Ohm impedances.
Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on.
The TM400X4ad is marine rated, featuring a two-part marine grade epoxy coated circuit board and UV inhibitor coated chassis, protecting the amplifier from the elements, making it ideal for marine, motorcycle and motorsports vehicles.
The TM400X4ad produces more power per square inch than any other model we make!

Keeping Cool in the Hottest Conditions
We use "dual fan forced induction" to pull the fresh air in, draw heat off the circuitry and drive it out of the amplifier. This ensures the amp continues to play even under the most demanding musical scenarios
Quick Disconnects Equal Quick Installation

Installed this on my 2019 Electra Glide Standard FLHT, using Sony MEX-M100BT head unit, with Infinity Kappa Perfect 600x and 900X speakers. This amp is LOUD and clear, with ample bass ! Was running an Soundstream Picasso Nano PN4.1000D for 3 years, but kept blowing tweeters because the wires would come loose from the amp due due vibration, it still works, and is a great amp, just not built for motorsport applications. The wires on the TM400Xad are soldered to pigtails then plug into the amp, preventing this problem. Also, the input and output clip setup makes it pretty much impossible to blow speakers, would highly recommend this amp to anyone looking to upgrade their motorcycle audio system.

I ordered my first one and it had the wrong front speaker in plug, so I submitted for a replacement and they sent another right out, however the new one had the same wrong front speaker in aux cord. I contacted Rockford Fosgate and they sent me the correct attachment at no cost. If your putting this on your Harley like I did buy the installation kit from Rockford Fosgate and save 32.00. It’s 299.00 tax and all from them.Call Rockford Fosgate for your amp settings the tech support at Fosgate was amazing! They were all very knowledgeable and pleasant to speak with. Performance the amp is great my bike sounds amazing! Amp actually put out 550 amps. Each amp comes with a data sheet for your amp. I would definitely recommend this for your bike.

I added the speakers a year ago, and they were definitely better than the stock Harley speakers, but still not the sound quality I was looking for at higher volumes and highway speeds. Added this amp to the system, and WOW night and day, this thing really drives the speakers and puts out awesome sound! Highly recommend.
