Description This amp has a fully adjustable 12dB/Octave crossover with differential circuitry. Other features include a subsonic filter, a fully adjustable bass equalizer, and mute and delay soft start technology. The dB amps by Rockville use the top parts and components recommended by Rockville’s very own engineer. These amps are the best sounding out of any series we have ever created. They perform more efficiently resulting in even dB of sound. We created them to be 2 ohm stable just like the world’s most famous amps by Rockford Fosgate, Kicker, etc. If you compare our amp to the most famous amps you will find our amp can compete and, in my opinion, surpass the performance of anything in its class. Each and every amplifier we manufacture is tested twice. Once at the semi-finished PCB stage of production, and then another test is done at the final assembly. We also run age tests on them. After this is all done, we hire a 3rd party independent company unaffiliated with our factory or with us to go to the factory and inspect 20% of all the production items.

Replaced a couple Boss amps that I didn’t do my research on first (amplifier benchmarking) and I spent less money on this and then I did for the other two. Rocksolid amplifier. It does warm up pretty quick when you’re pushing it but it did not get hot. Very happy with the purchase. Only problem I have is that when using the low pass option for a sub there is no sub sonic filter. At least not adjustable, I was playing 19 hz tone to my sub and it was flopping pretty good with no audible sound. Was hoping it would have sub sonic filter set for either 15 Hz or 25 as an option. Update 8/9/2019: I've had this amplifier now for around 10 months now and it's still going strong. Have it hooked up through a pair of 50amp AC to DC power supplies in my garage powering 2x 400w RMS Floor Speakers and a 425w RMS Polk Audio 15" Sub. It definitely pushes out the rated power (as dyno benchmarks have also confirmed they hit around the rated CEA RMS power as stated). Extremely loud and clear music (my neighbors can affirm this too... ). I have a couple other car amplifier / custom sub installs in my house where I still have poorly rated amps and I'm looking forward to purchasing more Rockville products to replace those amplifiers very soon. They will not disappoint! Review: Rockville 3200w - Low price, great features. One thing I really like about is that despite being so affordable you still get the great features you need for hard-hitting, clear bass. Speaker and wiring terminals are higher quality than other models in its price bracket and offer tight, clean, reliable connections. adjustable low pass hi pass crossover. RCA output jacks make system expansion even easier, too! I’m not just impressed by the great value of the amp but the features you get, too. I’m impressed that such an inexpensive, solid amp still offers features others don’t. ## Features - High Power Output: Delivers 3200W peak power, 800W RMS, with 200W x 4 channels at 2 ohms and 135W x 4 channels at 4 ohms, providing robust and clear audio for your car's subwoofer system. - Advanced Sound Control: Features fully adjustable 12dB/octave crossover, subsonic filter, and 12dB bass equalizer for precise audio tuning. - Efficient MOSFET Technology: High-speed MOSFET power supply ensures stable and efficient performance, enhancing overall sound quality. - User-Friendly Design: Includes remote dashboard subwoofer control, LED-illuminated logo, and RCA line input/output for flexible installation and easy operation. - Comprehensive Protection: Equipped with IC-controlled protection circuitry to safeguard against overheating, voltage fluctuations, and short circuits, ensuring long-lasting durability. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0728K1GD4 | | Best Sellers Rank | #50,822 in Electronics ( See Top 100 in Electronics ) #108 in Car Multichannel Amplifiers | | Brand | Rockville | | Built-In Media | Amplifier | | Customer Reviews | 4.4 out of 5 stars 702 Reviews | | Item Type Name | Car Amplifier | | Item Weight | 14.4 Pounds | | Manufacturer | Rockville | | Mfr Part Number | dB45 | | Model Number | dB45 | | Unit Count | 1.0 Count | | Warranty Description | 1 YEAR | ## Product Details - **Item dimensions L x W x H:** 9 x 2.4 x 21 inches - **Manufacturer:** Rockville - **Maximum Supply Voltage:** 16 Volts (DC) - **Minimum Supply Voltage:** 8 Volts (DC) - **Voltage:** 8 Volts ## Images ![dB45 3200W 4-Channel 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs - Image 1](https://m.media-amazon.com/images/I/61xWRpZM9WS.jpg) ![dB45 3200W 4-Channel 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs - Image 2](https://m.media-amazon.com/images/I/71cIoIX2oBL.jpg) ![dB45 3200W 4-Channel 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs - Image 3](https://m.media-amazon.com/images/I/71rNx6KQBGL.jpg) ![dB45 3200W 4-Channel 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs - Image 4](https://m.media-amazon.com/images/I/71ulAUdoB3L.jpg) ![dB45 3200W 4-Channel 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs - Image 5](https://m.media-amazon.com/images/I/71lUPwUtNtL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid performance, awesome budget amplifier! *by J***R on December 14, 2018* DB 45 is an awesome budget amp!

Used amplifiers in the 90's and been out of the car audio world for quite a while. I ended up buying a sound stream amp because they were all the rage in the 90's only to find they are not so good now. It was blown anyways on a channel from the start. So went looking for an alternative that was as advertised. This comes with a dyno sheet from the actual test for the individual amp. I just have it hooked up as a 4 channel amp so can't say much on running it for a sub. It works great for what I use it for but is quite large. It doesn't really fit under the front seat but that's where it is. ## Frequently Bought Together - Rockville dB45 3200W 4-Channel 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals - Pioneer TS-W3020PRO, Car Audio Speakers, Full Range, Clear Sound Quality, Easy Installation and Enhanced Bass Response, 12” Speakers --- ## 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.dk/products/45168449-db45-3200w-4-channel-2-ohm-car-amplifier-high-speed](https://www.desertcart.dk/products/45168449-db45-3200w-4-channel-2-ohm-car-amplifier-high-speed) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-30*
