Great Sub!!

The following review is for R1S412, which is a part of the bundle you are viewing.

I have just purchased this sub and must say it is a beast! I have it in the lowest air space box being pushed by a Lanzar 1000 watt amp and it hits! Great buy for the money and Rockford always delivers good stuff! I would really love to hear this sub in a bigger box so I might build one later on, you cant go wrong with this sub(s)!

Good for the money

The following review is for R1S412, which is a part of the bundle you are viewing.

i was originally going to get a p3, or a fi ssd. I love rockford fosgate and i decided to go with their entry level sub since it was cheap :] i am free airing it as im writing this and i am very pleased because i only have it on maybe 20rms. the construction is very sturdy and the sound quality is good so far. my box should be ready within the week so ill post another review of it with the box. it can hit the lows, if your just looking for some bass instead of spending a lot of money on a bigger sub just get a couple of these

Great sub

The following review is for R1S412, which is a part of the bundle you are viewing.

I just installed this sub in my NISSAN ALMERA on a ported box (i know should be in a sealed box) and it is pounding really hard and I'm just using 100 watts rms on them. Bass is very loud and tight and its definitely doing a great job. If you are an enthusiast in car audio you can go for sure with this sub it will fit your needs

More Bang For Your Bucks

The following review is for R1S412, which is a part of the bundle you are viewing.

I was looking for some new subs for my Honda accord, I was looking into some JL audio 12's since I had them in the past, but the location I went to was no longer carrying JL products,so i figure I would get Fosgate since I also had hem in the past, well to make it short I was low on cash at the time I really wanted the P3 but instead I went with the R1 and man I just love the response of those subs when I need them to hit hard they do and when I need low frequency's they respond just as great, I have them in a sealed custom box been pushed by a mono block Hifonics of 600 watts at first I was scared to blow them with all of that power but the longer I had them the better I felt about them, now I just crank my volume with out a care and I know they will respond to my demands. I've had them for about 8 months and still as strong as the first day, they are a great buy for the buck I would definitely recommend them.

Wow Not Bad

The following review is for R1S412, which is a part of the bundle you are viewing.

ok so i was shopping around for some subs and i was about to buy some P2's but then i was like wth lets gives these a try, so i bought a pair and threw them in a sealed box and ran them off a RF Prime 2 Channel amp underpowering them by 100watts rms so 50 a piece and im shocked how good they sound for the money, bass is pretty nice and solid, sound quality is good, i cant wait to see how they sound like when i get the Punch-300 mono block on these suckers i think they will be as loud as the P1's but for less money
