## 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.

### ⭐⭐⭐⭐⭐ Review
*by B***B on May 3, 2017*

Purchased this RP-600.5 to run my whole system in my 16 Ram crew cab. Its running kicker 3.5 dash speakers, skar 6.5 coaxials in the front doors, skar 6x9 rear door coaxials, and a MTX Series 55 10" DVC sub. I first had it hooked to a Skar EV10 inch sub and it sounded ok but the prefabbed box for under the seat was too big so I ended up buying the MTX 55 DVC sub with dual 2ohm voice coils I'm running in parallel to the sub channel at 1ohm. It sounds twice as good and really pushes the sub and has been stable. The amp works flawlessly and has many nice features for the price. I am very happy with the RP-600.5. especially being able to run 1ohm stable on the sub channel. Amp is super quiet and I am not picking up turn on noises, induction noises, or any kind of distortion.
