Try NVX, alpine, kicker, etc. ### ⭐⭐⭐⭐⭐ Soundqubed for the Win! *by J***E on December 10, 2019* Used little amp to replace a hifonics 1200 Watt class A/B 4 channel amp and some how my car is much much louder with less gain! I also have a BOSS crossover with the gains even lower that I had with the hifonics amp. I dont have to go past 25 on my pioneer double din when before I had to always take it up to 30. All of my class A/B hifonics amps; 1600 watt 4 channels, 600 watts 4 channels, 1200 watts 4 channels, would run super hot and go into protect seemingly with the most conservative settings and this amp out performs them all! Most Importantly I can let more mid range frequencies through the amp without killing it like the hifonics. Had my doubts about a class D 4 channel amp because I have always heard that you compromise on the sound quality because of the way a class D amp sips power. Smaller footprint, class D doesn't get hot, loud, clear. I don't understand how this amp does not have more reviews. Don't debate, just get this amp! ## Frequently Bought Together - SoundQubed S4-100 Multi Channel Amplifier - 100W (RMS) 4-Channel Car Amp - 2 Ohm Stable - RECOIL RCI217-2 99.99% Oxygen Free Copper 17ft 2-Channel RCA Audio Cable Twisted Pair with Noise Reduction 2 Pack - RECOIL 20-Feet 9-Conductor Speaker Cable, 18AWG CCA, Ultra-Flex and Easy Peel Jacket, 4-Channel Speaker Wire and Remote Wire --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/86755499-soundqubed-s4-100-multi-channel-amplifier-100w-rms-4-channel](https://www.desertcart.tn/products/86755499-soundqubed-s4-100-multi-channel-amplifier-100w-rms-4-channel) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-21*
