Sound quality is great for price, a value that sounds comparable to high end for less. I’ve been installing stereos since the 1980’s and this is my secret weapon on bikes. Review: GREAT AMP!!!!! - GREAT amp - used on 2013 Harley Street Glide . sits on top of the radio in the fairing. This is basically the same amp as the SoundStream PN4.520, but several buddies including me find this amp a bit cleaner / louder. Specs are NOT what the say. even 100 at 4 ohm / 130 at 2 ohm is a bit overrated. I bench tested the amp along with others (- 20 to 30% power on 14V). running 4 speakers and bike ROCKS!!!! cannot beat the price.... BE AWARE: you most likely will lose FM stations (some if not all) due to Class D. this applies for Bikes, not car! ## Features - 2000-Watt max power, 160-Watt X 4 at 4-ohm, 250-Watt X 4 at 2-ohm, 500-Watt X 2 at 4-ohm bridged - 4-Ohm bridged/2-ohm stereo class D full range - MOSFET PWM power supply ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0072L7XIC | | Best Sellers Rank | #107,741 in Electronics ( See Top 100 in Electronics ) #267 in Car Multichannel Amplifiers | | Brand Name | Power Acoustik | | Customer Reviews | 3.9 3.9 out of 5 stars (152) | | Global Trade Identification Number | 00709483043749 | | Included Components | Car Amplifiers - 3 or more channels | | Item Dimensions | 13.5 x 6.5 x 3.5 inches | | Item Weight | 4 Pounds | | Manufacturer | Epsilon Electronics Inc. | | Material Type | Metal | | Maximum Supply Voltage | 24 Volts | | Minimum Supply Voltage | 6 Volts | | Model | RZ4-2000D | | Mounting Type | Surface Mount | | Number of Channels | 4 | | Output Power | 2000 Watts | | Package Type Name | Box | | Specification Met | California Proposition 65 | | UPC | 709483043749 182682362123 807031759248 151903167670 172304207444 872182703556 115970961272 168141302039 100177377599 808112572442 163120513659 809187127100 041114743322 804066808804 | | Unit Count | 1.0 Count | | Voltage | 6 Volts | | Warranty Description | Please contact the manufacturer | ## Product Details - **Item dimensions L x W x H:** 13.5 x 6.5 x 3.5 inches - **Manufacturer:** Epsilon Electronics Inc. - **Maximum Supply Voltage:** 24 Volts - **Minimum Supply Voltage:** 6 Volts - **Voltage:** 6 Volts ## Images ![RZ4-2000D 2000W Class D 4 Channel Amplifier , Black , 13.60in. x 6.30in. x 3.50in. - Image 1](https://m.media-amazon.com/images/I/51SFsSVQMaL.jpg) ## Available Options This product comes in different **Customer Package Type, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value amplifier *by K***G on March 24, 2026* Second one in several years.

I am by no means an audiophile or expert. I just like my highs and mids to be fairly clear for certain songs that I play (if that makes any sense). So far it hasn't shut off on me and been working good, from what I read with a few reviews. There are pros and cons to this amp, however I have no complaints and I'll use it till it goes out probably upgrade to a better one. Positives - I love the size of this thing. It's small and has sufficient power to push your coax/component speakers. If you're a casual listener like I am, this is a great buy to save on cost and space. I have it paired up to some ID components 6.5" and pioneer 6.5" coax mids with the gain turned half way. No overheating and shut off since installed. I don't turn up the volume on my radio much, but on occasion I do when there's a song that I really like. I drive about 30-45mins daily with the radio about turned up a little pass 1/4 of the ways and get more then enough sound from them. Negatives - The noise distortion that I've read regarding the FM transmission is true. Ever since I installed this amp, most, if not all of my FM radio station are very distorted. I can barely hear a good song without it cutting off every 5-10secs. This is due to the amp being a class D (supposedly) or maybe just cheaper components used, who knows! Have yet to try other more well known manufacturer so I can not compare. This is irritating so to remedy this, I just stream music with my bluetooth/iphone and not even listen to the radio stations. The installation of the speaker terminal are a bit tedious. You need to install the bottom wire into the terminals before you can install the top wires. If you don't it'll be tough to tighten the set screws to the bottom speaker terminals. And last, why would PA not use "Allen head set screws" instead of using phillips set screws? It's easier to strip the phillips head vs the allen head. I believe a few of mine are basically at the verge of being stripped. I'll have to replace them with some allen head set screws next time I decide to remove this amp. Over all, I'd purchase this amp again, ONLY if it was on sale. I would not purchase at full price. I do miss my radio stations from time to time. Will update if I can think of anything else. 06/2021 - Channels 1 & 2 gave out and also took my component speakers with it as well. Had to replace the amp and component speakers. ## Frequently Bought Together - Power Acoustik RZ4-2000D 2000W Class D 4 Channel Amplifier , Black , 13.60in. x 6.30in. x 3.50in. - Recoil RC4D True 4 Gauge Car Audio Dual Amplifiers CCA Wiring Installation Kits with OFC RCA Cable - DteeDck RCA Splitter 1 Female to 2 Male, 2 Pack - RCA Audio Video Cable Splitter Adapter, Dark Blue --- ## 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.ph/products/1642671-rz4-2000d-2000w-class-d-4-channel-amplifier-black-13](https://www.desertcart.ph/products/1642671-rz4-2000d-2000w-class-d-4-channel-amplifier-black-13) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-23*
