Description

The only thing thin about the CompRT Subwoofer is the mounting depth. Whether it’s on the road, sand, or trail, these tough subs work perfectly in nearly anything with a motor. Your car’s back dash. The bags on your bike. Behind your UTV’s seats. Add the weather-proof CompRT Sub to your ride without sacrificing comfort or storage space. Superior components make a huge difference. Dual voice coils, a unique heat management system and our signature red cone stitching all help to give you deep bass and outstanding reliability in our thinnest subwoofers. Heat is the enemy of endurance. To make our subs even more reliable, KICKER engineers developed Forced-Air Cooling to help our CompRT subs run 20 percent cooler.

Fits Ford Bronco Wildtrak
Great upgrade for the Bronco Wildtrak. You will not be disappointed. Sound is fantastic, I replaced all stock crappy Ford speakers to Kicker. Great sound at a great price, sounds better than my wife's Audi e-tron lol

Works/Sounds Great in our 2023 Bronco!
Our 2023 Bronco had the infamous subwoofer and amplifier delete which Ford started implementing in late Dec 2022 (if you have the "AM/FM,6 SPKRS,SDARS - 250.00" entry on your window sticker you have this delete). Purchasing/installing a late model Ford Fusion amplifier (FP5T-18C808-AB) and the 48CWRT674 6.75" 4 ohm Kicker subwoofer is an excellent, relatively low-cost way to correct the sonic impact of this delete. The Fusion amp mounts and connects to the existing OEM subwoofer housing and connectors perfectly. However, you must activate the Fusion amp via 727-01-01 (change xxxx x4xx xxxx to xxxx x6xx xxxx) in the ACM (Audio Control Module) using Forscan (2 mo. free trial) and your favorite OBDII interface before it will operate. The 6.75" Kicker fits the existing OEM subwoofer speaker opening almost perfectly. You will need to tap/drill holes into the OEM subwoofer housing to secure the speaker with 8 mounting screws/bolts of your choosing. Went with the 4 ohm Kicker (vs. 2 ohm) because a number of folks in the Bronco forums have commented the bass was tighter, cleaner with the 4 ohm. We were all-in for approx. $200. Big improvement in sound quality. Highly recommend this upgrade! ... show more

It fits in a box perfectly designed for a 6.5” sub or speaker.
This sounds good with my kicker ks 3.5” speakers. Running it in the rms range right now. Sound quality is really good. Hits the lows clearly.

Thumps
This was purchased as a replacement sub for my 2011 Honda Element and it absolutely THUMPS!

Well worth buying.
I bought this subwoofer to replace the factory subwoofer in my 2006 Honda Element. It's far superior to the stock speaker and I'm very impressed with the bass that this 6.5 inch unit puts out. Definitely 5 out of 5 stars.

Awesome replacement for my daughters 2004 Wrangler
Gave new life to her 2004 Jeep Wrangler! Installed professionally via Best Buy and they said it was a perfect size to replace factory. If you take out center console it installs into that. Just add some noise dampening padding and it sounds amazing. Probably could have done myself after watching him do it in 30 minutes. Highly recommend. ... show more
