    Good deal for loud ass bass

    Posted by Adam Wichman on Sep 26, 2021

    Was too lazy to design another box after I had just built one for my AB Hawk1244 in my Jeep XJ. I bought these and put them in the Gately Audio dual 12 flat pack in my focus. Fucking slams. P.S. I wish you guys sold AB products

    When I got the system installed only one of the woofers worked and was not able to return it because it was installed and the amp gave out pretty quick it was wired right and I had aftermarket power supplies but wasn’t able to return that either for same reason because it was already installed but other then that the one sub that did work sounded great that’s why I give it 3 stars.

    Double E series is bangin

    Posted by David on Jun 03, 2021

    I had purchased this series and it only took about 1 week for them to get it to me. The only thing is I had hot the upgraded install kit wich I highly recommend and they didnt give me a install kit. I contacted them and they where quick to respond. They had my install kit shipped under fast shipping the next day so I had to wait to more days to connect but it was worth it. I did not expect the amount of bass that came outta these speakers. For the price and brand your getting I would say it's a very good deal.

    Great value, good bass.

    Posted by Thomas King on May 26, 2021

    Wire at 1Ohm and gently push the limits of these speakers with this amp. They’re underrated, but at 1Ohm this amp can surpass even their limits. Still, awesome bass if you ease up on it just right.
