Q Power Quad 8in Underseat Front Fire Subwoofer Enclosure, Q-Bomb Ported Sub Box Compatible with Chevy Silverado Crew Cab, GMC Sierra Crew Cab 2007-2026

Sundown x8 v3 don't fit with out shaving box and removing rubbers on magnets. Ports also to small for these subs fuffs really bad on deep bass sounds. Overall box is definitely strong, looks great. Definitely recommend for smaller subs. Figured the port was to small for subs took a chance anyways. Fits great in 2019 chevy silverado crew

Great fit. Box fits 8s and the truck excellent. No need for seat lifters. Stick out just a tad in front . But not enough to be troublesome 👌

This Box is great installed a couple of ct audio meso subs and man does it sound good. Also it’s a very nice constructed box with that Bed-liner style finish. Well worth the money.

The box is great for hard hitting bass. It will not play higher frequency bass notes very well so you will need to have some good mid and high range speakers to complement the overall sound quality. I only gave it a 4 stars because it dose have some cosmetic dings from the manufacturer and you will need to predrill holes before mounting the subs. I had a couple of my screws strip the whole when mounting the sub. Overall I am very satisfied with the sound quality of this box. I have it installed in my 2022 Silverado crew cab with 2 CT 8" Meso subs (800watts RMS each sub) and a 3000 watts hifonics amp and I can't believe how hard this setup hits.

Sounds good! Using this with 2 CT Sounds Meso 8’s feed by a 2000.1 amp. Fits nicely under the bench of my 2014 GMC Sierra crew cab.

Have it in my 08 2500 hd sierra extended cab. Seat would need to be raised if you need to continue to use it.

Box does not fit under back seat of 2013 GMC Sierra 2500 crew cab like listing says, back seat does not go down all the way. The cut out for hump is not in correct location. Contacted seller so we will see how they handle the inconvenience of ordering wrong box due to incorrect item fitment.

I'm hoping the SKAR SDR-D8 will fit. The box came in 2 days after I ordered it. I was pleased at how fast. The box itself looks to be a good buy and is sturdy. It will be put to use soon. Toro R6 to push them 😈

First and foremost it looks nice. That said and considering the price you get what you pay for everything about the construction of this box is off. The mdf is too thin for 4 8" subs and the port isn't correct for this size of air volume, other than that the box fits nicely in my 2015 chevy highcountry. But you might want to consider upgrading if your on a budget. I only bought this because it looked cool lol but your best bet is side port and two 8" subwoofers. For testing I put them in my jeep wrangler rubicon and they do pound hard but just use some gasket or silicone around the subs. Good luck with yours!

Very well built, fits perfect, finish is consistent, I have 2 skar zvx-8’s and it hits very, very low.
