Easy to install, works great with Rockford Fosgate TMS65 Power Harley-Davidson 6.5" speakers. I have 2 speakers and this amp in the fairing and the sound is great and loud. Powerful amp.

Outstanding!
Robert from Westerly, RI on 9/25/2023

Outstanding! Installed two Rockford-Fosgate amps in my 2014 ultra limited with infinity 62ix, 6 1/2" Speakers in the front and saddle bags. One amp for the front and one for the bags. You must flash your Boom Box HD radio for this installation . If you don't, you will not like the results. Do yourself a favor and buy the Techno-research flash tool, it's worth the investment.
Pros: Easy setup and install, Plenty of power, well packed and fast delivery.
Cons: Do your own research before purchasing, because some of the individuals working at Crutchfield are inexperienced with anything outside the box. As far as the amp goes, I can't seem to find anything you could complain about. Again, do your own research before you buy anything.

Clean powerful
Jody from Loganville, GA on 6/1/2020
So tiny yet beautiful and according to included birthsheet nearly 600 watts. Easy to install and set up. Rockford's clip indicators take out all guess work or need for separate oscilloscope. Would buy again. Crutchfield was a big help and shipping it super fast.
Pros: Tiny yet extremely powerful, easy to set up Rockford does it again
Cons: None other than wish Rockford made compact sub amplifiers 3000 watts built around same design.

I was surprised by the power of this tiny little amp. Unfortunately it blew out one of my subs. But I had it wired wrong. It's small enough to fit under my car seat.

S from Broken Arrow, OK on 3/7/2019
Big power in small package! Running 2 RF Punch P1S4-10 and it is more then enough. I have an 02 avalanche so will need a capacitor, not sure if it would be needed on newer vehicles will not be disappointed.
Pros: Big power for such a small footprint!
Cons: None that I could find.

Sound Quality
Michael from Charleston SC on 12/17/2018
Very clean & powerful amp. I was very surprised, how small this amp actually is. Great features on how you can set it, to prevent it from clipping; so you won't damage your speakers. Very quiet, and stays very cool..
Pros: Quality product, very compact, but still very powerful. Other amps in this class are bigger, and generate more heat.
Cons: None

Great Amp
Mason from Hamilton, NJ on 11/18/2018
Great little amp. Have it pushing 2 RF 10s bridged at 4 ohms and it does amazing. The compact size of this thing is also insane, about the size of a small tablet.

Small size with IMPRESSIVE sound!
Christian from Hanover, MD on 3/28/2018
This little compact amp puts out a ton of power! I'm using this to drive a pair of Hertz 6.5 component speakers and am impressed. I have always been a fan of Rockford Fosgate products and their quality of build. Plenty of power with 125 watts @ 4ohms
Pros: Build quality Adjustability Size Price

Rockford Fosgate Power T400X2ad
Rick from Hyattsville, MD on 11/21/2017
Incredible amp. Extremely small in size, so it fits anywhere, yet extremely powerful. The only downside it has for my application is I wish the crossover point went higher then 250 Hz. Other then that minor issue, this is an excellent piece of car audio equipment!
Pros: Small size High power Clean power Easy installation
Cons: Crossover point could go higher then 250 Hz. Power connections are too small for 8 gauge power and ground wire.
