Fox Box 3 10 sub enclosure

The box is nice . It had to be modified to use the speakers that fox acoustic recommended for the box and instructions are very poor . Expected plug and play with video instructions for that amount of money. Also connection point for wires needs to be upgraded.

Sorry that you had a difficult time doing your install. DIY is not for everyone. The instructions are straight forward and they are on the listing along with other pictures. Trimming the hole for a sub with a cast frame is typical installation practice. There are 3 terminal cups that can handle 2000w each so they are more than adequate.

Was expecting better

The box fit great but its only 1/2" mdf and it does flex when turned up. Right now I have three sundown 10's on a jp23. When I upgrade the amp I will have to remove the box to add more bracing and change out the cheap terminals. On another note I was missing two bolts for the seat lift and it didn't come with any directions. For $700 i was expecting alot more

Amazing box

Always amazing, anything coming from fox acoustic is going to be solid. Clear sound, no rattle (surprising out of an 2006 super duty) and everything fit as it should. I had a little hang up on the seat lift brackets but one phone call and they walked me through. Customer service top notch, materials top notch, sound top notch.
