I used a 10ft extension so I could sit my laptop at the front of the vehicle while keeping the amp at the rear of vehicle. **Q: Can this remotely control overall volume level?** A: The remote will only control the output for channels 7 and 8 when set up as subwoofer channels **Q: What is the proper way to control a separate bass amp? I tried using included RCA speaker wire adapters into a second amp, but it sounds odd.** A: Make sure your bass amp has Speaker/line Level inputs such as the JVC KS-DR2001D, pre amp inputs won’t work. Go out off channels 7 & 8 of your JBL into the speaker/line level inputs worked great for me. **Q: Can you connect a subwoofer with this amp?** A: Yes, using channels 7 and 8. Not much power dedicated to it though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not for the faint of heart *by J***A on September 21, 2022* I love the amplifier but don't buy this thinking it is plug and play it is a wonderful unit but you better have a newer laptop to program it because it will not work without it but the features that it had are unparalleled for the price it can be used for any number of configurations from a single input up to 6 channels inputs I love it!!! ### ⭐⭐⭐⭐⭐ It works. *by M***! on February 3, 2026* Fits and works perfectly in my 2003 BMW Z4. With a aftermarket stereo. ### ⭐⭐⭐⭐ Nice amp, poor QA *by N***E on April 22, 2024* Just finished installing this into an NC Miata with Focal ISU200 components. It fit where the Bose amp was with some effort and a dremel, which is one of the reasons I chose the amp. The other reason I chose this is to upmix the front and rear center channels, which I prefer because of the help they provide when the top is down. I left the USB cable connected and wrapped up under the amplifier access panel, so any time I need to tweak the settings I can grab my laptop and get it done. The Good: I was able to configure my car very quickly. I left all the EQs flat because I just wanted it to work today, but I see a lot of configurability. It was easy to assign each channel to the correct speaker, and assign inputs to output channels. Assigning inputs to outputs took a little figuring out, but once I realized what was happening it was easy to configure correctly. The Bad: Poor QA. I don't know why, but output channel one would hiss loudly on startup for a random amount of time. I wasn't using channels 7 or 8, so I just moved the speaker on channel 1 to channel 7 and that addressed the problem, but I was not able to determine a cause otherwise. When I was first setting it up, the speaker on channel 2 wasn't working. I double checked my crimp connections, and everything was fine. I snipped one of the wires and checked with a multimeter and I was getting 3.6 ohms, so the speaker side was correct. Then I noticed that one of the channel 2 wires was poorly crimped and had depinned itself from the JBL harness. I pushed it back in as best I could and it held, but that was pretty dumb. ## Frequently Bought Together - JBL 4086AM 8-Channel Class D Amplifier Design with Digital Signal Processing - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals --- ## 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.br/products/235995837-jbl-dsp4086-8-channel-class-d-amplifier-design-with-digital](https://www.desertcart.com.br/products/235995837-jbl-dsp4086-8-channel-class-d-amplifier-design-with-digital) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-08-02*
