SUNDOWN AUDIO U SERIES 12 (1500WRMS) D4 OHM

WOW!!!! Let me start off by saying these are by far the loudest set of 12s I've ever had in my life period!!!! I've been playing with car audio since I was 14yrs old and I have of these in a d4s profab ported box on a jp23 at 1ohm in my civic. These subs hit soo freaking hard I've had people ask if I had 15s they are that RETARDED Loud! My deck lid and back window flex an inch and a half. All bullshit aside if I'm careful the back window is going to go! Lol d4s for life!! Buy these they won disappoint!!

I bought these speakers less than a week ago. They shipped fast. They came in perfect condition. I called the company with a question and they were able to help me with no problem. I put 2 of them In a 32 hz dual box wired to 1 ohm, 3500 watts rms. The speakers sound great right out of the box. I will be a return customer for sure.

This is a great subwoofer The shipping was fast and the packaging was good.

I bought this sub as my first major upgrade to my audio system intending to pair it with an MTX 1501d. I've had it in my vehicle for nearly a year now and this thing is still going strong and now is running on 2500w of sweet b2 amplification. Talk about an underrated sub! I've never smelt any coil burn and have only felt the dust cap get warm a couple of times. I've gotten my money's worth plus a good amount extra out of this one. Highly recommend.

Amazing sub. Sounds great, and looks even better. The guys at Down4Sound got it shipped quick and helped with any questions I had. Thanks D4S!!!

I would give a 5 star review for this, but one of my subs shipped missing the 4 piece stick on gasket. It was the one box that was opened to insert the D4S sticker. How ironic! Lol! I guess a strong gust of wind blew my speaker gasket out of the box and no one noticed! Lol! I contacted D4S several times about replacing the missing speaker gasket, with no response. I will be spending my money elsewhere now. Thanks D4S. You lost a customer.

All I can say is wow. I upgraded to U12s from Sa Classics. Wow huge difference in sound and running the same amp and I’m underpowered by at least 1000wrms. If your limited on room and can fit SA make the jump to U series. I’m impressed and amazed. Also the shirt is sweet too thanks JP and D4S! This was my first order and I’m a customer forever now.

Just got 2 12"s in the mail haven't installed them yet probably going to put a crescendo 4k on them if i get that amp but happy so far

The single X15 was hogging everything the DD M2C could put on it. Two of these on the same wattage have really outshined it. The lowlows aren't quite as pronounced, but everything else really pops and slams. Nice build quality too.

Very nice sub, hits really hard even with an old school kicker zx1500.1 amp. I think with an updated amplifier it’ll put out more. Shipping to Hi was really quick, overall great experience ordering from d4s. Thanks a bunch
