Arrived damaged.

The following review is for 12TKDV, which is a part of the bundle you are viewing.

Package arrived damaged and the return authorization process took a little longer than stated. Had to contact Fed Ex to pick up the damaged package as I didn't feel I should have to pay to ship something back that was delivered broken. I wanted an exchange of the product but they credited my Sonic Electronix acct instead. So I had to replace the order. The corner of the sub box is smashed by the tag on the box, and also the back wall of the box was cracked where the wire terminal goes. I hope they get the 2nd order here undamaged. We will see. PITA for something that seemed so easy!

So far very impressed

The following review is for SMW12D4, which is a part of the bundle you are viewing.

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.

Little Sub that could

The following review is for SMW12D4, which is a part of the bundle you are viewing.

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.
