Top off sounds terrible

2014 jeep 4 door. It was easy to install. Besides that it sucks. Its built for a jeep with a removable top. When the top is on sounds good. Take the top off and it sucks BAD. For this much money they did terrible research. I would never recommend this product to anyone. Since its a custom box you would think it would would have custom instructions. It did not come with that. It also leaves the sub that comes in the jeep. You would think it would replace it and not just a crappy add on.

Pros: Ez to install

Cons: Sound and sub that came with jeep doesn't get removed

I added this subwoofer to the stock radio in my 2017 Wrangler Sport. The install was not too difficult. Wow, it make a huge difference as the bass before was very non- existent. I would certainly recommend.
