Happy with the product. *update* Bought a second one of these for my new sub and amp now I can individually tune each sub to what I want. This is great value and simple To set up. This is for 12v systems but will Work on home stereo with the right plugins. ## Frequently Bought Together - BOSS Audio Systems AVA1210 7 Band Pre-Amp Car Equalizer with Gold-Plated Front Rear and Subwoofer Outputs - 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.co.uk/products/257994574-boss-audio-systems-7-band-preamp-equalizer-with-subwoofer-output](https://www.desertcart.co.uk/products/257994574-boss-audio-systems-7-band-preamp-equalizer-with-subwoofer-output) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-20*
