Love it

I order my skar audio sdr 12 2400 watts dual enclosure man oh man them rhings are beast n loud i got it three days with no damages and i order from skar again im very very pleased with my subs

It's kinda serious!

At first I had my doubts before placing my order but after hooking everything up I was completely shocked. Skar did a great job with these subs and box, nice deep bass and they do get low. This is a perfect budget build for anyone looking to have some daily bass and it also has plenty if you want to show off. I can't wait to fully break these subs in. These are the lowest rms subs I ever owned but they do not disappoint one bit. I give skar a 10 for 10 with this set up, and paired with the rp1500 these little beast put in work.

Love 'em!!

This is the first time in years that I've bought a subwoofer box with subs in it. I've been a firm advocate for sealed enclosures, but I wanted to try something different, and I didn't have time to build a box. So I bought these, and I just got them installed in the car on 5-8. Man, I'm VERY IMPRESSED!! Still breaking them in with the RP.1200.1D amp I purchased at the same time, and I've got the bass turned way down. Everytime I turn the stereo on and let it run, they seem to hit harder. I love 'em. I can't wait to get them fully broken in.

Loaded SDR dual 4ohm 12’s

Good job Skar audio

Very pleased

Bought these with the rp 1500.1 amp and it’s the perfect pair. Had to rewire my car and do the big three upgrade as well. This set up is power hungry. I ended up going 1/0 OFC all the way around and using 1/0-#4 wire reducers for downforsound.com since they are offset and will work with the amp since the remote isn’t in the center like most amps. This setup is over the top for budget for bang. My rear view mirror is useless, it just flops around and ends up pointing down at the back seat after a good bass line, has the trunk flexing and everything. If you are looking for a setup that wont break the bank and you want to beat down the block then you came to the right place. Been putting them through their paces since I took them out the box and haven’t had any issues. Only thing I could recommend is putting some kind of protection in the corners for shipping, seen another review saying their box was damaged. Mine had a slight dent on one side. Other than that it’s well packaged wood protecting the subs and plenty of foam but the corners from top or bottom could use something to prevent shipping damage.
