As a result, there is no Chuffing that you would generally get with a ported box, thus enriching the BASS & making the system more linear - Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s) - High Level Input - Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the CUBE8 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs - Phase Control - Phase control lets you adjust the speaker phase with the amplifier if your speakers or subwoofer are hooked up “out of phase” - Low Level Input - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the CUBE8 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers - Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it - Specs - Dimensions: 9.65” x 9.65” x 9.84”, Weight: 14.95 lbs. - Warranty - BOSS Audio Systems provides a Powerful 3 Year Platinum Online Dealer Warranty so long as the purchase is made through desertcart.com.

You always want more. I'm 48 and have it in my Nissan Rogue. It creates a Good sound in there. But even though I want to be deaf when I get out LOL. It works & Sounds Good. **Q: Does it include the wires?** A: No **Q: Is it water proof?** A: It would have a descriptor of 'Marine Grade' if it was meant to be exposed to the elements. **Q: Will I be able to run eight 40W 4ohm speakers off of this sub? Is that what this is intended for?** A: So 9 speakers total including the sub off a mono amp. I like your style! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good SUB for what it is *by T***Y on December 12, 2021* got this for a build in my ram 1500. it sounds good, it hits "hard enough" i would say this is for the older generations (like myself) that still want a symphony in their ride, but don't want to be young and annoying anymore. I'm a guy that never had a system pushing less than 2000W on 2 10's in my 20's. so i do kinda miss having to readjust my rearview mirror all the time, lol. BUT, overall, for the money, this sub hits well at 600W, sounds good and clear, and compact like i needed. i would buy it again. ### ⭐ Stopped working maybe 6 months . *by E***O on September 26, 2024* It stopped working and customer service never got back to me with a solution. Granted, this was a long time ago but I am barely leavin g a review ### ⭐⭐⭐⭐ Decent, average thump *by J***E on December 12, 2022* I expected more thump but it really doesn’t have any more than my shallow powered sub under my seat that’s smaller. If they could beef up the bump, it would be worth the money. ## Frequently Bought Together - BOSS Audio Systems CUBE8 Car Subwoofer and Amp Package – Built-in Amplifier, 8 Inch Subwoofer with Passive Radiator, Remote Subwoofer Control - 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.co.uk/products/283320803-boss-audio-systems-cube8-car-subwoofer-and-amp-package-built](https://www.desertcart.co.uk/products/283320803-boss-audio-systems-cube8-car-subwoofer-and-amp-package-built) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-22*
