Great motorcycle amps!!!

I have 2 mini amps running 6 - SKAR 6.5’s and 1 -10 inch sub. My system is super clean and clear! Both amps fit under my front fairing. Can’t wait to install a system in my son’s Charger.

Powerful and in a tiny package

Running my 6.5 and 5.25 components with no problem at 4x 4ohms. I had to even back off gains a bunch. Fits in the location I need it to fit and works great. Keep in mind I am only running it 4 ohms and this thing gets hot fast

Skar Audio SK-M4004D

I'm going to call this "The little amp that could!" I was looking for a powerful amp that wouldn't break the bank. I need it to power my door speaker which are 6x9s and 6.5s. Both pairs need around 90 watts RMS. I also need it to be small because of space restraints. I already owned an LP-1000.1Dv2 so I knew how good Skar amps were already. All I'm going to say is this little amp transformed my system to another level! Can not believe the energy this thing produces. Door speakers sound like little subs lol. I have been "Skared"... My life is complete now...
