RoadThunder 8" Amplified Vented Bass Tube

The MTX RT8PT is a compact, all-in-one powered subwoofer system designed to add significant low-end reinforcement to vehicles with limited space. This "bass tube" design combines an 8" high-output subwoofer, a specifically matched amplifier, and a vented (ported) enclosure into a single, cylindrical unit. Its slim profile makes it an ideal solution for truck cabs, hatchbacks, or even the small trunks of convertibles where traditional square enclosures simply won't fit.

The RT8PT delivers 120 Watts RMS and up to 360 Watts peak power. The vented tube design is engineered to increase efficiency and output compared to sealed boxes of a similar size. It features a polypropylene cone with a butyl rubber surround for long-term durability. To ensure easy integration, the unit includes both high-level (speaker) and low-level (RCA) inputs, allowing it to connect to either factory or aftermarket head units. It even comes with an External Bass Control (EBC) knob so you can adjust the sub's volume directly from the driver's seat.

This little sub ROCKS !!!

First off, this isn't a ground pounding hip-hop blasting sub.....it ain't no 15"er.

What this sub does is provide a punchy bass that fills in the lows more than well in my Dodge Megacab. I rarely run my sub level at more than 3-4 and it sounds great when listening to metal, rockabilly and old school country through my JVC head unit (no other amps in my system).

I am way more than pleased with this little sub.

It bumps!

I was a bit skepticle about going for the 8in sub, but decided to go for it anyway. And wow, I was sooo surprised with how this thing rumbles! The ported hole in the back of the tube blows so much of the bass out its amazing that all that thud comes from that little tube. For that same reason it can get a little "boomy" but with the remote bass control knob it isn't a problem if it bothers you. Since the amp is built in, the install was a breeze in my 99 honda crv. I highly recommend this to anyone who wants to complete their system without having your neighbors hate you haha.

Great little sub

I ended up buying this a few weeks ago, and couldnt be happier with it. Install was easy, it looks and sounds great. However, contrary to other reviews you CAN wake people up with this if its tuned in right, haha. It may be small but it can put out some serious bass for its size. I have it sitting behind the drivers seat of my van, and it rattles the whole van if i have it up that loud.

Again, this thing looks great, and sounds better. Got it hooked up with some 8g wire so its never going to run out of power.

if you are looking for some nice bass, but not to wake up everyone on the block, this is for you. It added the lows my music was missing and then some. I would not hesitate to buy another, or to recommend this to others

Nobody does it better!

With proper placement for its size this things is a bass cannon that produces no standing waves that radiate throughout the vehicle.

boomin' bass

So far I am very pleased with this unit. My install is in a 1999 explorer sport so no trunk. More than enough bass for a confined space. I would recommend this for a suv.

Solid 8" Sub

I made the mistake of getting this for my sedan. Sounds good with the back seat down but this is really made for a hatchback, SUV, or truck. Not that great on the lows but the mids are great. Songs with lows that use to slam on my 2 12"s barley hit on this but that's the only downside.

Better than expected

I was looking for something small, complete to give me the low end I was missing. This does everything I need and more. I would recommend if you want something to fill the low bass void.
