Smaller than my JL JX360 amp, and after slamming it stays cooler. Best amp for the money hands down, does its rated power. Only upgrade to electrical system is 2/0 gauge wire for the big 3, could use an extra battery but surprisingly headlight dimming isn't that bad.Update: Still extremely satisfied, this is in a little Integra with a 90 amp alternator and last night I had it slamming all the way on top of my JL JX360 and it was difficult to notice any headlight dimming with all my lights on... Just be sure to run huge wires for this to reduce your resistance and use proper terminals. I don't recommend ring terminals because they're cheap and suck, you want all copper lugs. One last note, I am actually using just part of my 2/0 gauge welding cable in the amp as it doesn't fit, so I will have even less resistance when my wire reducers come. BEST AMP FOR THE MONEY, nuff said. ### ⭐⭐⭐⭐⭐ Best bump for the buck! *by I***N on November 19, 2015* Bought this amp to power 4 12" Alpine Type R subs in my e39 wagon. I had it wired to a 2ohm load, and it sounded great. Until it made one of the subs pop a tinsel lead. Oh well, I thought, time to buy some new subs anyway. I picked up two American Bass XFL 1244s. Holy. Crap. These two subs, a ported box built to AB SPL 2-12 spec, and this amp at a 1ohm load... gets down. I have a shuriken bt20 in addition to my factory agm battery, 1/0 and 4g wiring, appropriately sized fuses. It doesn't present a big strain to my stock alternator, i see no light dimming. It's gained up a little over half way and the bass boost is also about halfway. I have an audiocontrol matrix line driver with an adjustable voltage knob. Having the knob at 3/4 makes my roof flap, rear hatch panels want to come off, and my doors shake violently. It's beautiful.I hate when people review and it sounds like this is the first item they've ever owned and they just love it with no other comparisons. Well, I've owned somewhere in the neighborhood of 50-60 sub amps in the last 10 years. I've had many different brands (alpine, mtx, RF, kenwood, excelon, etc). This is without a doubt one of the best 'bang for the buck' amps I've ever owned. Just make sure you can run it at 1 ohm, that's where it's happiest. ### ⭐⭐⭐⭐ Nice amp *by N***S on June 17, 2020* Don't listen to negative reviews. This amp is powerful and sounds good. 1700 RMS is great for the price. Everyone that's complaining in the reviews don't understandable the difference between RMS and Max power. --- ## 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.jp/products/93012788-american-bass-usa-ph4000-md-4000-watt-mono-block-amplifier](https://www.desertcart.jp/products/93012788-american-bass-usa-ph4000-md-4000-watt-mono-block-amplifier) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-07*
