  • Unbeatable box for the money!
This box is a beast. I have 2 American Bass XFL 12’s installed and they are picking up 35 hz and are very loud and clean. Box quality is very nice. Only downside is the terminal connector for the wires in the box are the odd small spades and make it hard to use a heavier wire to the speakers. I will be updating that. Other than that this box is a must have. ... show more

  • Deep and smooth bass not harsh sounding like some boxes
I purchased this to replace a kicker compr 2x12 factory box. that box was muddy sounding. my single 12 kicker sounded better but I really wanted a 2x12. I installed 2 kicker CompR dual 2ohm 500 rms speakers. This box sounds great it hits the lows the kicker box couldn’t hit it sounds clean not muddy. This is a very nice quality box. I did upgrade the wiring though. The wires that come with box are thin. Also be careful both the positive and negative wires were installed on the same terminal it would have shorted out if I didn’t fix it 1st. Other than that it’s very good and sounds great. Buy it you won’t be disappointed. ... show more

  • Just check it out really well the delivery guys are very rough
Just took it up looks good sounds good but I need better 12" woofers. They are only 1200 each my is 2ohm or 4ohm 6000w I can tell that some 3000w subs will sound better in my new box it is built well heavy the conners were a little scuffed on the back of the box ,but it's not bad. Seems like they all have this problem how hard is it to put extra protection over the conners it's not so do it. My box looked like it had been in a war or something. Should have taken a pic got to excited and forgot. Other than that it's awesome. ... show more

  • Sounds amazing!
Box sounds amazing with my 2 Skar Audio 12d4 EVLs in it. They fit nice and snug in the recessed flush mount. Hopefully this box last. I already blew a Rockville Audio prefab with Soundtream T5 Tarantulas and the Skars hit harder and handle more power as well with deeper lows. Will update after some time to let you know how it holds up to some serious bass for sure. But for now I would recomend only down flaws I found is the terminal cup is cheap so upgraded it with a SMD terminal cup and also the box material is only 5/8" not 3/4" wich makes me think it might not hold up. But thankfully I got it on the Amazon days deal so have 3 months to return it. And I have no issue returning a blown box if it happens within 3 months. Update: Well the box only lasted a couple weeks before blowing all the seals in it only running dual Skar EVL 12d4s wired to 1 ohm on 2500w RMS amp. Box sounded amazing and even made it hard to breath in my car but once the seals broke it sounded like my subs were blown apart when they're still in perfect working order and the box is all wiggly and loose. Good thing I got it on Amazon deal days and was able.to.return it with no problem for a full refund. I'm sure this box would hold up to subs with less power but 2500w RMS is way too much for sure. ... show more

  • Small
I had 2-12” Fosgate P-2’s. Not even close to fitting in the box. I would need atleast 1/4 inch taken out of the inside diameter for them to fit. I blame myself. I tried to do it cheap and now I’m down 130$. Don’t make the same mistake
