Equalizer doesn't work. *by W***. on Reviewed in the United States on October 10, 2018* Not recommend for utv. Equalizer doesn't work, Bass is at an extremely annoying level which kills any sound the speakers may be capable of. Also the "amp" gets excessively hot. Read description, before purchase. Not waterproof, and clamps fit 1" bars. Only giving two stars because this kit will get me by until my big system comes off backorder. ### ⭐⭐⭐⭐⭐ La calidad y el precio. *by N***A on Reviewed in the United States on February 1, 2021* Utilice para mí moto me gustó calidad de sonido. ### ⭐⭐ Equalizer doesnt work. *by J***E on Reviewed in the United States on February 9, 2018* Everything was there but the instruction we're vague and the speakers seem to have the bass on very load, it states it has an equalizer setting but it doesn't seem to work, I've emailed the company and am waiting on a response, the sound quality is trash unless the equalizer is fixed, will give higher rating if I can find out how to use the equalizer. --- ## 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.th/products/66703867-12v-4-channel-atv-utv-anti-theft-bluetooth-amplifier-sound](https://www.desertcart.co.th/products/66703867-12v-4-channel-atv-utv-anti-theft-bluetooth-amplifier-sound) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-01*
