The sub itself is great. Fits perfectly in the spare tire area under the trunk in a Kia Forte5 hatchback and really provides that much needed bass to a factory system. Installation was fairly easy as someone who's never really messed with car electronics before. The toughest part was figuring out the wiring harness and which colors fed the rear door speakers.
The misleading part is the bundle including the wiring kit. On receiving the equipment, the instructions in the box explicitly state that using CCA wiring will invalidate your warranty. There is no mention of this on the website as far as I can tell unless you look up the PDF manual for the sub itself. Why, then, are you selling a bundle to include a CCA wiring kit with a sub that will instantly invalidate the warranty? I would have paid extra for the NVX wiring kit that is OFC but again, not really knowing much about car electronics, I didn't know CCA was a no-no. Ended up having to purchase a Skar 8 gauge kit off amazon that was fully OFC to do the install on my day off.
