I actually bought this to replace my Pioneer D-class 1200w amp. The sound coming out of my speakers sound soooo clean, and powerfull. I have this installed in my 8th Gen Honda Civic (without a 2nd battery) but I do have this paired up with a Rockford Fosgate Digital Compacitor. All of my speakers are Rockford Fosgate full-range 6.5 speakers, but I also have tweeters installed (Pioneer). This amp doesn't seem that it sucks up too much energy from my battery, which I was aiming for. I had that issue with the previous amp I mentioned. I went with this amp also because I used to have a mono amp that drove a sub box I had, so I knew what it could do (I now have a powered sub installed in the spare tire. I wanted my trunk space back lol). But IF I needed to buy another one of these, I would. ### ⭐⭐⭐⭐⭐ It's a great company *by on Reviewed in the United States 23 January 2025* It came in at a decent timing and it hooked right up easily from when I had my old amp, works fine and sound is just as I expected! ## Frequently Bought Together - Rockford Fosgate R2-500X4 Prime 500-Watt 4-Channel Amplifier - Rockford Fosgate T1650 Power 6.5" 2-Way Coaxial Full Range Speakers - Black (Pair) - Rockford Fosgate T1693 Power 6"x9" 3-Way Coaxial Full-Range Speakers - Black (Pair) --- ## 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.com.ar/products/353704087-r2-500x4-500-watt-4-channel-amplifier](https://www.desertcart.com.ar/products/353704087-r2-500x4-500-watt-4-channel-amplifier) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-11*
