The RP-4500.1D is one of the two newest additions to the popular RP amplifier lineup from Skar Audio. It is the most powerful monoblock amplifier in the series. Designed for maximum power, efficiency, and reliability, every feature of this amplifier exemplifies its high quality engineering. This amp is rated at a conservative 4,500 watts RMS power at a 1 ohm operating load. No shortcuts were taken when designing these two high-powered additions to the RP Series; they are both strappable, and we even went as far as to include a 3oz high purity and thickness printed ciruit board. This amplifier comes with a remote subwoofer level control and bass knob allowing the user full control over their bass from the front of the vehicle. This makes for a great amplifier when looking for serious power to get your system loud, and will work great on a single subwoofer around 4,500 watts RMS or a pair of subwoofers around 2,000 watts RMS each. Class D Circuitry design.

    Using this to run 4 JL audio W7’s And all I can say is wow. Although it is a little power-hungry I had to run Dual 1/0 OFC to amp but this thing will make you hurt!!! Also bass knob wouldn’t work so I contacted d4s and was directed to skar audio and had a new bass knob and wire within a few days!! Hands down would order again!!

    I'll say this right now,hands down this thing is insane. I'm pushing 2 SKAR zvx-12v2's @1ohm and this thing is a beast. I highly recommend this amp,make sure you do your homework though,you need a good electrical system. I'm running skar 0awg all the way but..... I didn't read the need a 450amp anl fuse or better,this 250amp anl fuse only lasted about 30min. Got a 10 pack of 500amp fuses on the way,lol. At full tilt I was only dropping to 12.1volts and that's factory battery and alternator in a f150,although I am running a 3.5 farad capacitor as well.

    Works as advertised

    Very I’mpressed with this amp running it on 4 dc xl 12s witch call for 9k rms and this little 4500 can really get them moving other amp does get decently warm but it is putting out about 5000 watts at 1 ohm so would expect it to warm up
