It works great until i turn the boat motor on. Then it cuts in and out continuously. Ideas what might be wrong** A: I’m having the exact same problem. With te engine off it works just fine but ad soon as I turn the engine on in cuts and turns off. I made a completely separate cable and connection straight from the battery and the problem persists. I have a voltage gauge and volts go from 12.6 with the engine off to 14.4 with te engine on which is just fine. I even changed the voltage rectifier in my engine but the problem persists. Its definitely a problem with the amp. **Q: If i install this without a head unit can i control the fade and balance with the inline multi-function remote?** A: Not as far as I know ! **Q: What is the rms of the speakers?** A: 10 **Q: Will the unit still work from a smart phone if the remote gets lost or broken.** A: The remote is hardwired, if you lose it will not function ## Frequently Bought Together - BOSS Audio Systems ASK904B.64 Marine Boat 6.5 inch Speakers and 4 Channel Amplifier - 500 High Output, Bluetooth Remote, USB and Auxiliary, Waterproof Pouch - FXC Waterproof Marine Boat Rocker Switch Aluminum Panel 5 Gang with Dual USB Slot Socket 3.1A + Volt Meter Blue LED Light for Car Rv Vehicles Truck (KG0149-5B Blue) - 10 Gauge Marine Wire,10 AWG 30ft Duplex Marine Grade Wire Tinned Copper Oxygen-Free Insulated Red& Black Electrical Cable for Boat/Automotive/RV/Camper/Trailer --- ## 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.in/products/734053321-boss-audio-ask904b-64-marine-package-includes-500-watt-max](https://www.desertcart.in/products/734053321-boss-audio-ask904b-64-marine-package-includes-500-watt-max) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-09-11*
