I say they will make a great pair. If that head end has the features you want, then this little amp will give 100w max watts per channel over the 50w onboard. It can pump out a very reasonable volume level with plenty left over so that the sound doesn't get distorted. In fact, I wouldn't recommend getting anything more powerful unless you replace the speakers too. **Q: Does it come with the harness pigtails?** A: Yes and the RCA cables. Pretty complete. You will need a y connector on the RCA input side if you want to bridge the amp. **Q: How many rms per channel** A: 45 watts x 4 **Q: Ohm stability?Rms ratings @ ohm loads ?** A: 4ohm ## Frequently Bought Together - Kenwood KAC-M1814 4-Channel Compact Bridgeable Marine/Motorsports 400W Max Power Digital Amplifier - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals - DteeDck RCA Splitter 1 Female to 2 Male, 2 Pack - RCA Audio Video Cable Splitter Adapter, Dark Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/427611681-kenwood-kac-m1814-4-channel-compact-bridgeable-marine-motorsports-400w](https://www.desertcart.us/products/427611681-kenwood-kac-m1814-4-channel-compact-bridgeable-marine-motorsports-400w) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-20*
