Product Overview

I recently had the opportunity to try out the Rockville Rws12ca Slim 1200 Watt 12 Amplified Powered Car Subwoofer Enclosure, and I must say I was impressed with its performance. This is a great product for anyone looking to beef up their car audio system.

First off, let me start by saying that this subwoofer enclosure is extremely well built and durable. The enclosure is constructed of a high density laminated foam surround with a 3D molded acrylic dust cap and an expanded rolled steel basket which makes it incredibly sturdy. The ultra stiff composite pulp cone is reinforced with Kevlar which makes it incredibly strong and capable of producing some great sound.

One of the things that really impressed me about this product was its sound quality. The 1200 watt peak power output and 300 watt RMS make sure that you get plenty of punchy bass for your music. The high power strontium magnet with an ultra saturated high BL motor structure provides crisp and clear sound that will make your car audio system sound amazing.

The Rockville Rws12ca Slim Subwoofer Enclosure also comes with a built in 300 watt RMS/ 1200 watt mono block amplifier, 150mv 5v variable input level, 24db low pass crossover frequency 50hz 250hz, low level RCA inputs, and high level speaker level input with auto start music sense which makes installation incredibly easy. It also comes with an RJ11 jack for dash mounted bass remote so you can easily control the volume from your dashboard or steering wheel.

Overall, I highly recommend this product if you are looking for a powerful subwoofer enclosure for your car audio system. It is well built, produces great sound quality, has easy installation capabilities, and comes at an affordable price. Whether you are an audiophile or just someone who wants to add a bit more bass to their music, this Rockville Rws12ca Slim 1200 Watt 12 Amplified Powered Car Subwoofer Enclosure is definitely worth checking out!
