Description

Skar Audio engineered the RP-150. 4ABM marine amplifier to set a new standard in high power marine amplifier performance. This four-channel marine amplifier is 2-ohm stable and utilizes a wide array premium internal components, such as its high speed MOSFET power supply as well as an advanced marine grade PCB board layout. Conservatively rated at 1, 000 watts RMS power (250 watts x 4 channels), this amplifier will bring the speakers on your boat to life with unrivaled power output and sound clarity. The RP-150. 4ABM is extremely versatile as well with its compact physical design, which allows it to fit in a variety of tight or small locations on your boat. Also present on one side of the amplifier is a built-in user control panel that is fully adjustable - allowing you to dial in your sound exactly how you want it. Featuring adjustable controls for gain, high pass filter, low pass filter, a crossover switch, and more, you'll have full control over your listening experience. In addition to all the above features, this model also features four-way protection circuitry, which will give the user the peace of mind knowing they are protected against damage to the amplifier for various reasons - including electrical shortage, overheating, low voltage, and more. Our marine amplifiers feature a special marine coating internally that allow them to withstand the harshest conditions for long lasting use. Finally, the RP-150. 4ABM also utilizes a powerful cooling fan that is mounted on the inside back plate of the amplifier which helps keep the unit cool even at the highest levels of power output for extended periods of use.

    • 5.0 out of 5 stars way better than competition in this price range.
Size: 1000 Watt Class A/B 4-Channel
I had bought a rockville amp that was about 20-40 bucks cheaper, used it for two trips and didn't like it so I replaced it with this one in a similar price range and all I can say is wow, spend the extra 40 bucks and get this one. I got the 1000watt 4 channel and I'm pushing 4 speakers off two channels and the amp gain isn't even half way up and it still sounds better than the competition. very pleased now I have room to add extra speakers to this amp. PS. This amp also has a built-in fan which dramatically helped keep it cool compared to my other one. Definitely happy. ... show more

    • 5.0 out of 5 stars Crazy powerful amp..:
Size: 1000 Watt Class A/B 4-Channel
This amp is crazy powerful… I had 4 8” Skar speakers on this amp and I can’t turn the gain up past half or else it will sound like it is going to blow. I could easily add 4 more of these speakers to this setup without a problem. If you are getting 4 8” Skar speakers get the 500w amp. This amp is very powerful and don’t think this amp isn’t powerful enough for your setup because it definitely is. ... show more

So first off, I have a Sony headunit with dual RCA outs, the one with 6 channels of course was out of stock. No problem, there is always a way. So from the head unit I used the RCA to hook up to the equalizer which has the 6 channels out I needed. From the equalizer under the head unit I have a 6 channel RCA going to the trunk to meet up with a crossover, the crossover then uses a dual RCA to feed the mono block amp, I went with marine grade 800 watt matched to a Skar 10" 1600 watt, 800 RMS. Then I have a 4 channel RCA cable from crossover to 4 channel Skar amp, I went with 1000.4 marine amp. 2 farad capacitor for the mono block amp, I have 2 99' Maxima's so I bought 40' of 9 connector wire which goes from 4 channel amp all the way back to the head unit to power all door speakers. All in all it was just under $1,300 for everything, and you can't put a price on good audio, full install done by me and a help from my cousin. It's all wired up now and these images are from when I first started the install, I'm going to wait about a month till I make my amp rack so I can easily adjust or make adjustments easily before permanent install, sub is wired down to 1 Ohm and for a 10", it bangs. ... show more
