Review: Great quality - So far so good. A truly 1 ohm stable amp. Great customer service. Thru a previous experience not on desertcart. But with the company direct. And it wasn’t their fault. That’s on fed-ex. Quality amp at a great price. From someone who has been into car audio for 36+ years.

## Questions & Answers

**Q: Can i run 8 speakees on this?**
A: I currently run six on just 2 channels. Pay attention to the ohm load and properly set gains with a multimeter prior to playing.

**Q: What size fuse this amplifier carry**
A: For every 100 watts of RMS power, you will want a 10-15A fuse. So if you have a 1,000RMS watt amp, I would run 125A-150A fuse.

**Q: Would this amp be appropriate for skar audio vxi65 360-watt 6.5" 2-way component speaker system?**
A: This is a class A/B 4 channel amp. It works great in your application.

**Q: Will this amp power 4 skar audio sk 6x9s good i got 2 skar audio vvx 15s on a skar rp 2000.1d and i don’t want the bass to drown out the voice**
A: Yes, this amp is shouldn't be your concern.  I'd be worried about those 6x9s handling this amp. I say that because though I really like Skar I've had no luck with their 6x9s. Good news is I haven't owned these sk 6x9s so you may be in luck. This amp is powering a pair of audiopipe CSL-6904 6x9 & a pair of Infinity KAPPA-93iX 6x9s in my car with a Skar EVL-15 pushed at 1 ohm with an audiopipe 1500w monoblock & fixing to strap it. The clarity of the 6x9s are wonderful at any level.

### ⭐⭐⭐⭐⭐ Nice amp
*by A***R on February 12, 2026*

Lot of bass works great for the price

### ⭐⭐⭐⭐⭐ Insane bass for the money, easily pumps a pair of 12s
*by S***I on December 30, 2025*

I’m running the Skar Audio RP-1500.1D on two Pioneer TS-A3000LS4 12" subs (4Ω SVC, 400W nominal each). Wired in parallel for a 2Ω load, this amp is rated 930W RMS @ 2Ω, which is basically perfect for this setup, and it absolutely slams. What I like: Hits HARD, stays clean: Bass is tight and punchy, with way more output than I expected from a “budget” mono amp. Easy to dial in: The onboard controls (gain/LPF/subsonic) make it simple to get the subs blended without sounding boomy. Remote bass knob included: Super convenient to tame it for everyday driving, then crank it when you want to show off. Solid build / practical features: 4-gauge power/ground terminals and protection circuitry give peace of mind once everything’s installed properly. Fits nicely in a tight space! Worth noting: Like any real sub amp, it rewards a solid electrical setup (good power/ground, clean signal, proper tuning). Once it’s set correctly, it just goes. If you want strong, chest-thumping bass without spending crazy money, this thing delivers. My two TS-A3000LS4s kick HARD on this amp and it’s been a great match.
