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

  • Great sub for the money , missing wires though
Hits HARD. It’s in my 2022 f 150 and it slips under the rear seat no problem I love the sound it’s nice and hits hard I feel it in my chest and it rattles your teeth… Seriously great for the $ BUT I did NOT get the 8 gauge wire for the ground / power in the box. Luckily I had some ready to go. Be aware. I will update later if there is any issues … as of now!? FULLY worth the money ... show more

  • Cost effective... adds sub-lvl base but you wont get the boom for $250
The box has excellent construction. The speaker grills dont really offer much protection but they do look nice if protection isnt required. 2000W/500W RMS amp... ummm. This unit clips out at 60% volume which is a shame. Base heavy songs even less. I like that this unit was bundled together complete with cabling and at the price was a good value - Would I buy it again? Hard no. I would like base to make it to 75% volume without having to dial base down. Wish I would have purchased Amp/Speakers separately. ... show more

  • Does not last.
Sub worked for about a month then started shaking horribly. Was offered to send it back to east coast for same price as purchase to evaluate. Couldn't afford to ship it so took it down and found the inside glued poorly and broken. Now I have a speaker cabinet that is broken and sounds like crap for my money. I would not recommend this product. ... show more
