Useful

I bought this because I had a Visa Gift Card to spend, but it wouldn't cover the full amount I was planning to order, and paying with 2 different cards online can be a hassle. It was nice to be able to buy this and apply it to my account when I made the order.

The only complaint I really have about it would be a faster turnaround time. I had to wait about a day for it to process before it applied it to my account. It would be nice if it just applied it right after you bought it.

Good little sub!

I was looking for a shallow sub for the side of my Vw polo IV trunk. I wanted some extra bass for my system but not like the bigger subs I had. When I played a couple of ours i raised the volume and was surprised how powerful it was for such a shallow sub! So if you want a shallow sub that gives good bass this is the one to buy!

great subs for a great price

I installed two of these in my 2008 nissan frontier and sound absolutely amazing! I highly recomend this item for anyone looking for great bass in a tight space

Great sub

I bought two of these for my Chevy Avalanche. I needed a sub that I can install without altering my truck. These are in individual 0.55 cubic feet boxes under the rear seats and I have a MB Quart RAB 1450 amp pushing them wired to 1ohm (about 450 watts RMS) and they sound great. I kept my factory Bose system and just added this setup and I'm very satisfied. There's plenty of bass inside and outside my truck. Definitely recommend for anyone especially if you have limited space.

Nice for the price I will buy again thank you

10" MB quart

So this is a great sub all though I burnt it up because an idiot tuned my amp in haha

Just like its cousin...that's a good thing.

This sub is the same as the Hifonics Gladiator GLX10D4 (which was $30 cheaper), just with MB Quart graphics on it. I have one in a sealed .8 cu. ft downward firing box (no polyfill) with 320W RMS. The sub plays low and is tight -sounding already, so no need for me to go with a smaller box and polyfill to compensate. I got it because it can be 2 ohm configured to match my amp's RMS output perfectly. It's a great-sounding sub and fits my application well. I haven't tried to put it in a ported box since the manual does not say it's OK to do so, but I think this sub would be much louder and still retain its tight sound in a 1.0 cu. ft ported box. That would defeat the purpose of having a sub capable of shallow mounting though...so small sealed it is. With some break-in time, I hope it does get a bit louder than it is now, but I am satisfied with the low end range in my small sedan. Sensitivity is a bit low at 82 dB, other shallows I own go as high as 90 dB so you can hear them better at lower volumes. If you need a shallow sub, this one will fit the bill - but you may want a little more oomph if it's in your trunk and not in the cabin with you.

Good for small systems with no bass.

I put 1 of these under the rear seat of my Quad cab sierra denali. There was plenty of space for it plus an amp. But didnt produce enough for my liking. For the price and mounting depth it is pretty good. If you want to feel the bass you will want multiple (4+) There is just not enough excursion to get much SPL or db out of one or two. But they were pretty clean. So if a little fullness is all you need than these will work and u can save a Little $ too.

nicely compact!

Bought it based on size, since its going under my back seat in my 2005 f-150, im running only one 10" in a tight box with the factory radio, tight bass sounds..good sub!

Beyond Expectations!! Awsome Sub!!

I was searching for a slim sub for my 1998 Chevy Suburban. I found this MB Quart RLP254 and liked the specs I read. I had to design and build my own custom enclosure just because I wanted it to be under the middle seat on driver side. There are plenty of available enclosures out there that this sub would work perfectly in, just not for my exact design. I was able to get the enclosure to .77cu.ft. and packed full of heavy poly-fil just like the specs suggests. best part is the box is completely out of the way and "invisible"!! After all said and done..... WOW!! This sub hits hard and is extremely accurate and tight! Just one 10" sub fills my full size Suburban with clean, accurate, tight bass like some other 2-3 sub systems I've owned in the past, of course it doesn't pound the side walks loose like those systems but if I were to run 2-3 of these MB Quarts I bet they would with ease! If your looking for a high performance slim designed subwoofer... look no further!!

Nice Sub

Perfect sub for a smaller box. I have it in a small sealed enclosure with heavy polyfill. Hits hard and clean. MB Quart is quality and you cant beat the price here.

Great Subwoofer, great price

Researched a little on subs. Found this sub for best fit on budget and specs. Built homemade sealed box aprox. .25cuft as manual says for each. Placed behind f250 crew cab seat. Powered by a mono block 1200w amp. Did previously buy first sub from diff. Store at higher price. These 10s perform great. Very clean bass. Highly recommended.

MB Quart RLP-254 10" low profile sub

Low profile sub sounds great, clean sound, highly recommended.

great sub

I put two of these in a Ford Explorer yesterday I had to do a budget system so the only thing that wasnt dual waz these subs I put two in a box that waz way to big for them because of the customers wants but surprisingly they hit pretty hard I had a dual 300 watt amp hookt up to them (300 is RMS for one and i waz pushing about 250 watts datz 125 a sub if setup right) and these subs flext the back glass thiz waz on a 600 dollar build including the wire and dana mat and all the other odds and ends

Great Subs

I purchased thease for my wifes truck, was greatly impressed with the sound quality. Great subs!

Better than expected

I bought 2 of these for the storage compartment in a 2007 Trailblazer. Well we bought a minivan and guess what I get to drive. Anyways very impressed with these little subs so far. I have them in a 1.3 cubic ft box with medium fill and an 1100 watt Diamond Audio amp wired at 1 ohm. Not broke in yet and they fill the van nicely and don't take up the whole back. Definately recommend

Very nice sub

This has great sound for a shallow mount 10" sub.

awsome

awsome
