Gotta love them 15s

This is my first purchase of the 2011 line of Punch subwoofers and I must say I like the design and look of these better than the previous line of which I have two 12", although those are wonderful subs as well. I don't really have room for a 15 in any of my vehicles but was missing that deep, "feel it not hear it" bass that only a 15 can provide so I got one of these to add to my garage stereo and I am very happy with this sub. I am pushing the P1S4-15 off of a Fosgate Power 500bd @ a 4 ohm load so the sub is getting at least 250 watts rms and it seems to be a perfect match. I doubt my neighbors are gonna like my new toy very much.

Nice 4 Da Price

Man! These subs really bang. They slam and can hang with the big boys. I put 2 of these on hifonics brx1000 @2ohms and they got down. I couldnt believe how loud and deep they were. Well worth it!

Cant beat it for the money

I was skeptical that I would be satisfied with an entry level sub after being in the game as long as I have but I was wrong. I installed it in my wife's SUV on 250 watts in an Atrend sealed 2.0 ft sealed box. Sub moves lots of air and produces alot of deep bass you can feel. This is a good set up for someone just getting in the game or thats tight on cash for the sub and box shipped cant be beat.

Great Sub For the Price

I have 2 of these on a prime 500-1 in a prefab ported box. They did a 142 on the meter. Great subs for the money and I highly recommend. Sonic has great service to I got these in 2 days with just standard shipping.

Rockford Fosgate Punch P1S4-15

Very pleased with these subs. Have 2 running off of a MRV-M500. 500 rms Alpine amplifier. Large sealed box. Subs never bottom out and are pretty tight for entry level subs. I was sceptical at first but I am very satisfied with this purchase.

Always Great Products!:) Fosgate thanks

I had a 12' ported box many years ago and this fosgate 15" with a 2 channel 1000 watt class ab amp and WOW this thing has some bass!!!
I have found its better to have more power than what the speakers need so that the speaker gets a clean undistorted signal with some MAJOR bass! For eighty-nine dollars on sale that's so Awesome, I bought a second one. I rated the 5 on durability, time will tell but so far Great, as with anything it can be treated right and last or recked in short order.
I used the sealed box and with the extra juice it still gives a clean hard hitting bass!:)

Thanks team fosgate, and sonic electrinix!

P1 series fozgates are awesome

I have not found any cons with this speaker setup I'm running to 15in P1 series with only a 500-watt Fosgate amp and it's louder than most of the cars around including my neighbor that has three 2000 watt each 12 + 3000 Watts plus excellent value hits hard as hell.
