    Worth it

    Posted by kurt merriman on Dec 19, 2022

    I’ve been in car audio since 1998. This is a similar box that i would build and is really nice for a daily driver system with quality not quantity in mind. I would recommend. Just be ready to switch the sub out.

    Better then JL Audio!

    Posted by Jon Salinas on Sep 01, 2022

    I have never used anything else other then JL Audio subs since 1997. I read some really great reviews about this unloaded box on Youtube and of Sundown subs so I gave this combo a try for a system I built for 2nd car of mine. This E Series loaded box is WAY better then my JL Audio HO112RG-W3v3 ($600). It's a night and day difference. This $287 box killed my $600 JL box. Such a big difference that I just ordered a 2nd Sundown loaded box for my other car. This is a hell of a deal for what u get!

    12” E Series Loaded Enclosure

    Posted by Luis Leos on Mar 16, 2022

    Wow! Just received this yesterday and hooked it up. I wasn’t expecting too much at it being the E series but the enclosure must be done really well. I have yet to even turn it up full way and may not even have to because it’s hitting good about halfway turned up! Box is a little big so make sure you have the room.
