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. ## Frequently Bought Together - Skar Audio RP-75.4AB 500 Watt Full-Range Class A/B 4 Channel Car Amplifier - Skar Audio RP-1200.1D Monoblock Class D MOSFET Amplifier with Remote Subwoofer Level Control, 1200W - Skar Audio 4 Gauge Amplifier Wiring Kit - Blue, Copper Clad Aluminum, SKAR4ANL-CCA --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/20785785-skar-audio-rp-75-4ab-500-watt-full-range-class](https://www.desertcart.co/products/20785785-skar-audio-rp-75-4ab-500-watt-full-range-class) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-07-10*
