Tru spec 15 inch subwoofer box

It seems like a Quailty box so far. I just got it installed earlier today. I have a skar vxf 15. It slams in this box so far. Have it on a 1/3 of power to get it broke in. Very pleased so far! Will update if box blows apart lol

Decent box

Not a bad box for a quick build, but I was suggest building a similar box out of Birchwood for better resonance

Good box for the money

Not like other cheap prefabs. Solid build and good output

Amazing box for evl 15

Loved adding my own stainless studs to the box. Still waiting on my fabric to come in so I can wrap it but this box is amazing with my evl 15 in it. Beating the absolute crap out of my 2014 escalade and easy to stand up for when hauling luggage. Definitely recommend this box. Closest to custom you will ever get in a prefab box and they hit hard
