I have 4 of these bad boys in a sealed box hooked up to a t1500bdcp and they get down literally good job Sonic Electronix

I bought this sub a while back and it was really loud for a single 12. It was on 600 watts rms and in a sustom box it my car. Ive never had a problem with it. The oversized cutout that Rockford Fosgate has may result in you needing a custom box just for the baffle.

I have 2 of these in a custom built box paired with a hifonics brutus 1700w amp and could never be more satisfied. I have no complaints with this subwoofer. All I can say is these subs are a great buy for your money.

I have these 2 subs in a sealed box because I'm limited to space in the trunk of my 2012 Malibu. I got the box from Sonic also. they sound amazing. I have them being drove by the t1000-1bd and the 2 are a almost perfect match. The only reason I say almost perfect is I'm scared to turn the bass gain up until I break the subs in. I was at bat between buy 2 of these subs or 2 alpine type r's and I'm not disappointed with my choice by no means but I can't speak for the type r's. I can tell you that you will not be disappointed by these subs than sound amazing...

Im runnin 2 of these subs in a sealed box on a hifonics zeus 3000 watt amp and it will get dumb loud. Iv never had the first problem out of these subs except they cracked my box. I run them every day and they don't get hot and never miss a beat they hit high bass good and the lows are incredible they made a big crack in my windshield. I love these subs ans don't plan to replace them unitl they go out with 2 t2d212s.

I had the subs for about 4 months. In that time I put them through 3 different boxes until I found the 1 that worked the best with them. I had them wired to a usamps md1d Merlin mono block 1200w rms/ 2400w peak competition amp. Ran them in competition and hit a solid 138db without even trying. Great sub for the price, would recommend to anyone who wants a decent sub for a great price.

they sound good, except wondering why one of them has turned a gold color over time... Idk if do to heat and sun shining on them or if its a defect...

I love the p3 line from rockford but the pvc boot is not a good add on, yea it looks good if u invert the sub but it also can cause more heat build up. Other than that i think it solid but I don't know if these are as good/reliable as tje 500 rms older models (light grey cone) those could take some power for long periods.

Man, I had the older versions before, and they burnt out on me. So, Sonic gave me credit and a discount on these, and man they hit stupid hard. I just need a better amp than the Boss amp I have, 'cause I know they have more potential. I am straight with these 12"s. Oh yeah, make sure you have a strong box, 'cause they will break your woofer box apart. That's how hard they hit in a 2003 nissan max.

Have it wired to 1 ohm. Running a rockford 500-1bd to it with 8 awg speaker wire. Hits hard! It's still being broken in. Great bang for the buck, have it in the 2.8 cubic foot wedge ported box they sell on this site, nice sub box.

Just hooked it up today to my old school Power1000bd @ 4 ohms. I got roughly 520W RMS going to it (when amp is all the way up). It's halfway and this thing hitsss. It surprised the hell outta me. Upgraded from hx2's big difference recommended to everyone who loves clean tight bass.

These subwoofers are so amazing when compared to the previous models. I have a single 12" in a 4.0 cu.ft. custom box that is tuned to 35Hz. As a result of the large port area, the sub gives an extremely low, deep, clean bass! It absolutely bumps even when underpowered. So as far as spl goes, well. You figure it out.

I have owned two of these now, as an upgrade from my old cheap subs. The first one blew after about a month. After some research into the box, it appeared that, due to some moisture in the box, it was possible that was the cause. So we bought another, made a custom box (what was recommended by RF, by the way) and made sure everything was sealed properly so this wouldn't happen again. I owned the sub for about 2 months. No issues. I noticed it would heat up rather quickly, but nothing too major. One day, on the way home, I was running the sub around 75% or so and it managed to melt a coil. It was broken in quite well.

At this point, although I was impressed with the sound/price ratio, I will not be buying another sub from them. Melting a coil like that should not happen once, much less twice.

I've had mine for about 3 months now and it slams in my truck. Definitely getting a second one soon. Great buy!

Out standing product one of the best sounding subs I've ever heard.

This is a great product. Looks good and sounds even better. I bought two of these and I am using the t1500-bdcp amp to run these. Bangs so hard but is nice and clear. Provides great bass and would recommend to anyone.

I've only had this sub for 3-4 weeks and I have blown it. My local audio shop checked everything and they have no clue why it would have blown.
