Rockford Fosgate

The following review is for TM400X4ad, which is a part of the bundle you are viewing.

My item arrived packaged well, is much smaller than I imagined and will be great for installing in my boat. I have used the T series amplifiers in the past in cars and have no doubt this amp will be perfect for my 4 boat speakers. The killer deal I got helps too! Took advantage of the additional warranty as well.

Update:
Installed this amplifier with a Kicker install kit and Kicker marine speaker wire, 4x 6.5" M1 marine speakers and the Memphis SMC3 head unit.
Seriously the best audio system I've ever heard on a boat, gets super loud and is super clear with phenomenal bass for 6.5" speakers. Sounds better than my buddies boats with wetsounds and JL setups and I only spent about $1,000 for the entire system. Setup with the built in clipping indicators made it easy to achieve full safe volume. Set my HPF to 50hz.

Fosgate TM400X4ad – Small Amp, Big Attitude!

The following review is for TM400X4ad, which is a part of the bundle you are viewing.

Running the Rockford Fosgate TM400X4ad in my 2013 Harley-Davidson Electra Glide Limited with 10 speakers, and let me tell ya this thing flat-out bangs. It’s small enough to tuck away clean, but the power it pushes is unreal. Crystal-clear highs, deep bass, and it keeps every one of those speakers screaming even at 80 down the highway. I’ve had people turn their heads at stoplights wondering where all that sound’s coming from — then I point to this little beast and they just shake their heads.

This amp runs cool, never clips, and delivers pure, clean power every ride. Rockford Fosgate really built a monster in a mini package with the TM400X4ad. Trust me you can hear me long before you see me roll up.
