So far very impressed

So far very impressed, bought with the Atrend 12tk shallow truck enclosure bundle for Black Friday, at a total of only $120, it’s great so far. Installed it behind the rear seats in my 1995 f350 crew cab, paired with a Skar amp. So budget friendly was the goal. It sounds amazing, very clean and crisp, and hits way harder than I was expecting. Build quality seemed great, especially for the price. So far so good! Give it a shot if you’re in the market for a shallow mount subwoofer! Wont be disappointed.

Amazing Shallow Sub

These sound killer. Worked perfect for my C10. Amazing freq response with tons of headroom. Big bang for your buck

Little Sub that could

Needed a sub for my Nissan Hardbody. Very limited on space in a single cab. Mated with Skar 350 mono in a sealed box & it’s like a concert inside. Bass drops & plays any genre with clarity. Would definitely recommend.
