Skar Audio RP-75.4AB 500 Watt Full-Range Class A/B 4 Channel Car Amplifier

So far so good . Time will tell

I'm really impressed with Skar, they are the only company that I know about that doesn't lie about their specs. Other companies use really good rose colored glasses for their specs.The model # for the amp I just bought for my stereo is RP-75.4AB, this is the 4 ohm spec. It actually puts out 75 watts RMS at 4 ohms on all four channels without clipping. Now that's only 300 watts total for what they call a 500 watt RMS amp, but they also spec out for 2 ohm load which is 115 watts RMS, 460 watts total. I think this amp is really intended to be used with a 4 ohm load going by the model #.My first encounter with Skar was with my Karaoke system sub amp. It's a RP-1200.1 and it really does put out 1200 watts RMS into a 1 ohm load, just like the spec says. I liked Skar so much that when I started looking for a 4 channel amp to replace my 2 McIntosh MC240s in my stereo, which I wasn't having much luck with, I thought about Skar and searched for Skar amps. I found the RP75.4AB, it's a class AB amp which I like for full bandwidth and it's still 65% efficient. My Macs also run class AB but they are only about 40% efficient plus there's the power used by all filaments which makes the actual efficiency even lower. In other words the Macs are room heaters. I just ran my stereo with the Skar amp for about an hour with good volume and the amp is barely warm. It also sounds really good, I was hoping it would sound as good as the Macs but instead I was surprised it sounded better, it was cleaner at mid and high ranges. The Macs probably need new tubes so that would explain the difference in quality, which is the main reason I bought the Skar amp to begin with, THERE ARE NO REALLY EXPENSIVE VACUUM TUBES TO REPLACE! This would have cost way more then what I paid for my new system using the RP75.4AB.

I got 2 of them hooked up to 10 door speakers in my conversion van and they sound great

Skar never let's me down ...great product as always

I wanted to add an amplifier to my car audio set up and the Skar products come in at a perfect price point for the avid car audio enthusiast. The sound quality on the amp meets my needs. I’ve had plenty of playtime on this amp and it works flawlessly even when cranked up.Can’t beat the quality for the price! Would highly recommend this item.

Had it in for about 6 months so far with no problems. Have it powering 4-6.5 and a super tweeter. Gets loud

Bought this to upgrade my factory amplifier after replacing my radio, has been working great for over a month now with no issues and does not overheat in the slightest bit, even with it in an area with no air flow in the back of my car. Get no unwanted noise in any of the channels and gets my mids and highs as loud as I want them. Have them powering factory mid-bass and tweeters in my front doors and column, and in the rear a set of pro audio from Skar as well. Would recommend for a cheap 4 channel to anyone needing one.
