Key Features: Integrated 120 Watt RMS Amplifier 8-Inch High Output Subwoofer Vented Enclosure Design High and Low Level Inputs for Easy Connection to Any Source RT8PT Amplifier and Vent View 40 Years of Experience This universal amplified enclosure was designed for new enthusiasts looking to experience what adding bass to their music sounds like and for those hard core bass fans who have unfortunately had to grow up and can no longer drive around with three 15-Inch subs in their trunk. The 8-Inch high output woofer used in this unit includes a lightweight and durable polypropylene cone that efficiently moves air for excellent output. The integrated class D amplifier can deliver up to 120 watts RMS power to the subwoofer using either high or low level inputs, so it is easy to connect to any type of radio. The unit also includes an external bass control that can be connected to the amplifier and mounted near the driver allowing for adjustment on the go. Review: Great deal for the price - I love this subwoofer for the price and for my needs. I drive a Toyota Tacoma double cab, and have this mounted in the middle of the back seat (almost looks like an arm rest). It is larger than it looks in the pictures, but I have yet to see any smaller subwoofer/box/amps out there. This guy definitely improved the sound of my stock system by 100%. It doesn't necessarily shake the truck, but can bump if you want it to. Keep in mind that I do have it set up to my stock head unit, so it simply spliced into the rear speaker wire and not plugged into a subwoofer port. I understand this, but this only requires that I change a few settings on my head unit when I switch between different genres of music. I listen to everything from classic rock to alternative to rap to electronic music. This seems to sound better for certain genres over others. Classic rock music: Sound is great, it almost sounds like the guitars/bass guitars are playing in the vehicle with me. I recommend turning the bass lower for classic rock, but it provides a nice deep background. Pop/Alternative: Requires some tweaking between songs sometimes. Some songs sound great, others will shake the sub too much and drown out other noise. Overall, still sounds pretty good. Rap: This is mainly what I listen to while driving. I've noticed that it's real hit or miss depending on the frequency of bass in the song. About 75% of music sounds great, without that BUMP that other subs can give. Some songs will try to bump really hard, and this sub can't take a huge peak amount of bass, it's more for RMS bass playing steady. I like to actually hear music, and this adds a new dimension to rap without being obnoxious. Electronic: This sub really shines playing most electronic music, as it plays a nice steady bass instead of bumping like some rap music beats. Really sounds good, even turned up pretty high on the bass. Country: I hate country. I won't even test it out for one song for this review. Overall, I'd recommend this sub setup for any vehicle, not just for a truck with a small space. If you like steady bass, and not thumping/bumping/shaking bass, this is the one for you. For the price, you won't beat it. I got this fully installed in my truck for about $50, so all together about $200 total. It looks great with the carpeting, and I'm definitely satisfied with my purchase. Review: Strong Punchy subbass - Strong bass for an 8inch subwoofer, Built in amplifier with a bass knob.

Value A ### ⭐⭐⭐⭐ Nice tight package *by R***D on January 31, 2016* This MTX sub does just what i need it to do. I have a Regular Cab f150 so i have very limited space. Btw im 6'8" so I couldnt use a conventional external amp and shallow mount truck sub because every inch is precious to me. Thats where this unit comes in and saves the day. It was a breeze to install because it has a built in amp. This MTX sounds AWESOME! Big sound in a small package. I paired this with a new Kenwood head unit and kept the stock speakers. The supplied remote gain control is an awesome addition that i installed under my climate controls. The sub sits right behind me and the cab isnt that big so i guess thats why it sounds so good. Although I love this unit, i found the limits to it rather quickly. Dont get me wrong this little unit THUMPS! I can feel my music... but I just want alittle more power out of it. ## Frequently Bought Together - MTX Audio RT8PT 8 Inch 240 Watt Car Loaded Universal Powered High Performance Amplified Tube Box Vented Subwoofer Enclosure, RCA Connectivity - Scosche Install Centric ICAK8 True 8 Gauge Hybrid OFC 2-Channel High Current Amplifier Wiring Kit Complete Car Amp Kit Twisted Pair Audio Cables, In-Line Fuse Holder - Kicker 46KISLOC2 K-Series Stereo Line-Output Converter w/Remote Turn-On Output --- ## 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.tn/products/1178028-audio-rt8pt-8-inch-240-watt-car-loaded-universal-powered](https://www.desertcart.tn/products/1178028-audio-rt8pt-8-inch-240-watt-car-loaded-universal-powered) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-24*
