Or should I say “was” junk. First off, from the beginning the remote bass knob never worked right. Lots of static and electronic noise unless you positioned the knob just right. It was so bad that I ended up disconnecting it and just adjusting the bass through the head unit. Now for the bigger problem, IT DOESNT WORK ANYMORE!!! I’ve had this thing for less than 6 months and it’s fried! Called pioneer and they want me to pay to send it in. Not happy about this thing at this point. Buy and use your own risk and don’t rely on the warranty if you do have issues with it. ## Frequently Bought Together - Pioneer GM-DX871 - Powerhouse Amplifier with 1,600 Watts, Class-D Technology, 1-Channel, Variable Low-Pass Filter, Compact Design, and Remote Bass Boost Control - Pioneer TS-A301D4 - Powerful 12-inch Subwoofer, 1600 Watts Peak Power, Dual 4 Ohm Voice Coil for Powerful Bass - BOSS Audio Systems KIT10 4 Gauge Amplifier Installation Wiring Kit - A Car Helps You Make Connections and Brings Power to Your Radio, Subwoofers Speakers --- ## 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.sg/products/107075686-gm-dx871-1600w-max-class-d-mono-1-channel-car](https://www.desertcart.sg/products/107075686-gm-dx871-1600w-max-class-d-mono-1-channel-car) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-15*
