Description

The Rockville RG212CA and RWK81 bundle is the perfect solution for drivers seeking a powerful, space-saving bass upgrade. Ideal for sedans, SUVs, and hatchbacks, this dual 12" powered subwoofer system comes paired with a high- quality 8-gauge amp wiring kit for a complete, ready-to-install experience. The RG212CA features a built-in Class D amplifier producing 500-Watts RMS and 2000-Watt peak output. Its two 12" slim subwoofers are housed in a precision- tuned vented enclosure, engineered for deep, responsive bass. Despite its dual-driver design, the enclosure maintains a slim profile—just 6.65" deep at the base—ensuring compatibility with tight trunk spaces. Built-in RCA and high-level inputs make the RG212CA compatible with both aftermarket and factory radios. Smart design touches like a remote bass knob, angled terminals, and an adjustable low-pass filter enhance flexibility and usability. A built-in limiter ensures clean output, even when pushing high volumes. The subs are wired to present a 2-ohm load to the built-in amp, optimizing output power and efficiency. To complete your installation, the RWK81 wiring kit delivers maximum conductivity and signal clarity with 100% copper RCA cables and a heavy-duty 60A AGU gold-plated fuse. Flexible power, ground, and remote wires allow for easy routing, and the abrasion-resistant PVC jacket stands up to extreme heat and oil exposure.

  • Fits in 2 door jeep wrangler trunk
Having 0 experience with car audio I bought this for my 2 door jeep wrangler and with limited trunk space these worked perfectly in my vehicle. Probably over kill but they’re plenty loud when I have the doors and roof off, this definitely helped my situation. When it got cold out side in the 30s my car wouldn’t start, confused I believe the amp was drawing constant power. Note I do have the remote shut of switch wired correctly to my head unit. I installed a kill switch on the power wire to the amp under my seat, since then know problems. For my vehicle I’m pleased over all, if you’re tight on trunk space I recommend this all in one setup. ... show more

  • SUBWOOFER SMOKING!!! SUBWOOFER SMOKING!!!
I would give this subwoofer a 0 star rating if I could I would like to start off by stating when I first received the sub in the mail the box was a beat up and ripped up as if it was thrown around and not properly cared. When I first installed it had barely gave my car a small bass boost I barely had noticed the bass difference even after carefully calibrating it . I noticed a weird smell almost like ramen noodles coming from the speaker as well. After a little research I heard it could be from the glue or chemicals they used to make the box and it should go away eventually but never did . One day I turned my car on and the power indicator on the remote was not on so I looked in the trunk and noticed the 30 amp fuse on the amp was blown I replaced it and played some music the protect indicator kept lighting up and it started smoking from the vent ports . I’m very upset as this was my first subwoofer and heard decent things from Rockville . I will definitely stay away from there products in the future and will not recommend anyone to buy there products as you will be let down . The same amount of money I spent on this i could’ve gotten some new decent kicker subs or even some used professional subs like sundown . ... show more
