Is it compatible with the GM-D8601/GM-D9601 series?** A: Yes with zero issue! **Q: Will this work on a orion zstreet amp?** A: Yes but that D amp already comes with a bass controller ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by J***N on June 14, 2025* Great product and mounts easy ### ⭐ DOES NOT WORK older silver Kicker KX1600.1 amp! *by J***E on January 4, 2024* All the new Kicker amps use a 3.5mm jack now, but the older ones used RJ12 with only 4 conductors & the wires reversed at each end of the cable. So even if you reverse the 4 center conductors that Kicker uses, the amp does not supply the power necessary for this bass knob to function.Sadly I am forced to buy a RCA bass know the adjust the output from the radio to the amp instead, since Kicker no longer makes the bass knob for their own amp ;-( ### ⭐⭐⭐⭐⭐ Doesn't work *by M***6 on June 21, 2024* The connection to the amp isn't secure enough. The knob loses power/connection after a few minutes. --- ## 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.co.uk/products/524294286-xmsjsiy-bass-control-knob-remote-amplifier-replacement-bass-controller-car](https://www.desertcart.co.uk/products/524294286-xmsjsiy-bass-control-knob-remote-amplifier-replacement-bass-controller-car) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-31*
