Q Power12 Inch Dual Subwoofer Box, High-Performance Vented Speaker Enclosure, Black - Car Audio and Sound System Accessories - Portable Equipment for Subwoofers

The old saying of "you get what you pay for" could not apply more here. This box is incredible. I have it hooked up with two of these Rockford Fosgate P2D4-12 Punch P2 DVC 4 Ohm 12-Inch 400 Watts RMS 800 Watts Peak Subwoofer powered by Rockford Fosgate Prime 1,200-Watt Class-D 1-Channel Amplifier and it is insane. I figured with this type of equipment the box could just be your run at the mill $30 build it yourself job... I couldn't be more wrong.This box is the cherry on top of this system. It's got impeccable construction and extremely durable. It's not a huge box so should fit in most standard sedan/4x4 trunks. If you've got a truck or a small hatchback it might be a snug fit/no go.It's made and lined with the same stuff that truck beds are lined with. Making this is tough, however I had absolutely no issue screwing my subs down into it. Because of this there are no cracks or edges where air might escape or cause the box to rattle. This is a HUGE plus for me. Delivers pure bass.Something to note when you are hooking it up to the 4 terminals, this box did NOT include any sort of wiring. You must use your own speaker wire to connect your subs to the terminals, inside and out. Other boxes I've dealt with in the past typically include this. The terminals are located on the back of the sub (vs. the side) so standing it up may pinch your wires.I would recommend this box to ANYONE who cares about their car audio experience.

Love this speaker box!!! They provide a great quality sound and are easy to work with.

Super bien

You know i was extremely Weary about buying a box i knew nothing about and never heard of but i went a head and bought it and i could never be happier with the sound this box puts off. My last box i had wouldn't let them hit at all and i thought i bought crappy subs but my entire truck shakes now with the box. For the price its amazing i wish it was more hide-able but its a pretty big box. I have 2 12” 600 rms watt subs and a 1200 rms watts amp and this box topped it off tight around 450. Again amazing quality id want nothing else.

Build quality and finish are excellent, cubic volume is a bit small though. Nothing that can't be addressed with appropriate drivers for it. Using 2 as a pair, internally wired in serial with 4 ohm drivers to create 8ohm load. Then boxes wired in parallel to drop them both back down to 4ohms, powered by a 4 ohm plate amplifier. The ports help keep the plate amp cool through forced air from driver excursion. They dont sound as good as the VL boxes but the reduced footprint has its applications. Recommended when space is limited, a great sounding box with the right woofers

I’ll start off with overall I’m pleased with the box I waited until the box was used for a while and there’s no separation no cracking in the coating or any issues with the performance of the boxNow my only problem/complaint was my American bass 12’s didn’t immediately fit I had to sand the coating off the inner ring on both sides due to the basket rubbing but I’m still pleased overall with the box

Sounds Great

Just install to my american bass h2 12s not even a hr playing and box lineing is starting to apart it self not good enough wood or coated or bonding I do recommend if are competition Subs by American Bass kickers jl's or any other type of competition sundown subs I also had sand and make the sub holes bigger to make my Subs fit I'm going see if can get refund and send this box back
