Review: IT’S NOT THE AMP’S FAULT! - ***UPDATE 8/4/18*** I went mudding a week ago and accidentally sank my jeep in a pond 🙃 Completely flooded the floor of my interior and soaked the amp, luckily it was off. A couple days later I ripped the entire interior out and washed it out really good, like literally washed the inside of my jeep with a hose. I figured the amp had already been soaked what more harm could I do. Got everything back together after drying out, fired up the jeep, turned the stereo on and BAM! Perfect sound quality. If it can get soaked twice and still work I think that says something. *end of update* Did you know, that running your power lead in close proximity to your audio cables can cause loss of sound clarity, distortion, and you guessed it, alternator whine?! I’ve had to fix plenty of botched installs due to this. I did a little test and ran my audio cables directly next to my 4g power lead going to both my amps. Heavy whine and almost no signal clarity. Re routed my cables to run on the opposite side of my power lead and wow! Signal was clear, bassy, and no alternator whine. This amp is phenomenal and woke up the old Bose speakers I pulled out of a 2001 Pontiac GTP (2ohms at 50 watts RMS, give or take). I drive a Jeep Wrangler TJ and space is precious, so I can’t have big amps and fancy subs. This fit under my driver seat perfectly and cranks some serious audio to my speakers, even with the top down. Great price for a quality low budget system and I get lots of compliments from friends. GREAT AMP!!! Review: Good value/economy range amp. - It's a cheap, inefficient, class a/b amp. It's not winning any awards at show, but its driving a 12" and adds a little bass to my meager system in my daily driver. I've had this for 4 years now. It survived a car flipping end over end early in its life while being completely unsecured. A little dented and bruised, it has continued to serve faithfully through the years since. If you need something modest, you don't need to blow the latch off your trunk, and don't want to spend a lot of money, this is a decent amp for the cost. ## Features - Power - 100 Watts Max X 4 @2-Ohms, 50 Watts Max X 4 @4-Ohms - Class A/B Topology - Class ‘A’ Amplifiers Have Enormous Amount Of Current Flowing Through Its Output Transistors With No Audio Signal.

Now with that being said your 10" sub will not handle 2200w it will only handle very short peaks of 2200w and it would have to be clean wattage. this amp will push it well set it about 3/4 and X it over at about 90hz **Q: Can you support two 10" subs with this one amp?** A: Hello. Yes, this amplifier will support two subwoofers. You will need to make sure that each subwoofer does not exceed 400 watts peak power. **Q: will this amp power 2 6x9 500 watt door speakers and 2 rear pillar speakers?** A: It will with ok sound quality if it's for inside the car listening pleasures. However getting another one and bridging it or a higher powered amp for a good baseline would be recommended. ## Customer Reviews ### ⭐⭐⭐⭐⭐ IT’S NOT THE AMP’S FAULT! *by J***N on July 2, 2018* ***UPDATE 8/4/18*** I went mudding a week ago and accidentally sank my jeep in a pond 🙃 Completely flooded the floor of my interior and soaked the amp, luckily it was off.

GREAT AMP!!! ### ⭐⭐⭐⭐⭐ Good value/economy range amp. *by J***T on April 28, 2025* It's a cheap, inefficient, class a/b amp.

Small powerful amp. Only setback is that has no crossover, full range only with volume (in voltage) control. ## Frequently Bought Together - BOSS Audio Systems R1004 Riot Series 4 Channel Amplifier Car Audio - Class A/B, 400 High Output, 2-8 Ohm Stable, High/Low Level Inputs, Full Range - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals - BOSS Audio Systems CH6530 Chaos Series 6.5 Inch Car Door Speakers - 300 Watts (Pair), 3 Way, Full Range, Tweeters, Coaxial, Sold in Pairs --- ## 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.vn/products/1121438-r1004-riot-series-4-channel-amplifier-car-audio-class-b](https://www.desertcart.vn/products/1121438-r1004-riot-series-4-channel-amplifier-car-audio-class-b) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
