## Description

Introducing the Rockville RTB65A Powered Subwoofer Tube. We at Rockville just had to manufacture a high quality powered bass tube. Growing up one of my best friends bought a car and it had a powered bass tube in it. The sound that it produced was just amazing and I will never forget it. Bass tubes push out some of the punchiest bass available. I personally love punchy bass that is deep and clean. Bass is an integral part of any good audio system, and the Rockville Bass Blaster amplified subwoofer tubes will add power and impact to your car audio system. The cylindrical shape of the enclosure helps focus the motion of the bass pressure so it maximizes that punchy output from both the woofers face and the tuned rear aero port. Strong deep bass will fire through your vehicle for astounding results. Since this is a powered bass tube, you get everything you need! This is your entire bass system. The built in power amplifier will push this tube to the max. The amp, sub and enclosure are perfectly tuned and matched to sound perfect together. Installation is a breeze! No need for building and wiring enclosures to amplifiers. Simply power, ground remote and send signal to the bass tube and you are ready to enjoy the most incredible bass you have ever heard. "Good things do come in small packages" Rockville Bass Tubes will fit every vehicle without taking up valuable space and provide super low-end bass response. No permanent installation is necessary, the tubes come complete with 4 mounting legs and Velcro mounting straps so your bass tube will stay put where you place it.

Review: Great bang for the buck! - A great subwoofer amp combo that is just enough to finish things off without being to expensive and overpowering. Piece of cake to install and use.
Review: Práctico - Genial facil instalación y queda perfecto, el sonido es bueno para percibir bajo con el sistema de agencia

### ⭐⭐⭐ Awesome power
*by R***O on 1 August 2023*

I bought the little 6.5 inch and it absolutely hammers bass for its size. Now after 6 months of use the amp is cutting in and out randomly. Even playing music at low level. Disappointing. The sound is great. The lifespan sucks.
