Amazing sound, deep bass and easy to install
I had high hopes for this setup and was not disappointed! I installed it in the spare tire of my Ford Excursion and it sounds great! I would say it hits a bit harder than most factory subwoofers in most newer cars which is all I was looking for.
I drive a truck with an extended cab and wonder if anyone has installed this 12" sub inside a car/truck cabin? Most the under seat 8" to 10" sub sound weak. Thinking this would fit under my rear bench seat and with the 12" driver sound awesome.
this subwoofer saved my peace of mind while driving. I listen to music & sing my heart out! I recently purchased 2020 Audi and could not believe how crappy the audio sounded. Did some research & found that Audi installed a 6 1/2 speaker in a spare tire assembly that really didn't cut it. I knew that setup worked because I had a Bose system with one...Looked at forums that said Cerwin Vega was decent. I wasn't looking for crazy window rattling bass. Just something that makes you feel like you're at a concert thank you Cerwin Vega. I take my dog with me often. I looked at her while my music was playing and she even had a smile on her face
This thing kicks butt! Sounds great. I love how it fits in already wasted space.
