Rockford Fosgate P3D4-15 with Ported Enclosure

Great value

Great price and works fine I know pre fab boxes ARENT ideal but if you do go with one this is not a bad option

Extremely impressive!

I went to a local audio shop and heard these 15s on my t-1000-bd amp and it hits so hard. I was gonna buy them from the shop until they said how much they are asking. This is the best website for any audio enthusiast. I will never purchase from a different online store for car audio or home audio.

P3D4-15

I have two of these on a T 1000-1bdCP and they do a nice job.
They are in a Nissan Versa hatchback. I put them in a ported box.
These sub are by-far better than any other sub in this price range, at
least I think they are, You should be able to buy this sub and know
it's money well spent.
I took a few stars off because I think they should have the SWIFT
connection like the T1 and T0 subs and then it would be five stars across the board.

great product

Great quality and performance very good price good looking and fast shipping.

High quality

This sub was amazing, sadly I burned up the voice coil: too much power from the amp running to it. Just ordered another one and excited to be thumpin again

backup sub

great sub I have had lots of Rockford gear over the years and this thing is built well I use it wen my custom 15 goes to my buddy for a rebuild every year. and I run about 800 watts on it of a hifonics zues 3200.1 at 4 ohm no problems and for u guys that don't know the coil will always look burnt it has a black coating on it what ever it is it works.

Rockin

these thing are nice got 2 running a 1ohm off a BRE1600 getting 700 a pice I'm about to get a BRX1600.1d.Got 2 in 1 sealed box pushin the amp to the limit and they don't heat up at ALL i can be heard 2 or 3 miles no bu**s***. my bro hears me for 10 minutes which would be bout 5 to 7 miles driven time pluse bout to have the 2000 watt amp a a t2d2 on my old 1600watt amp rockford is one of the best buy and run them with at least 800watts

Sick Subs

I have a pair of these P3 15s' in a sealed box on a 1200.1 prime amp and i am shocked that this low end amp bangs so clean. After booming for hours the amp and subs are cool to the touch, amp birth-sheet rates it at 1400 rms so each sub is getting 700 rms @ 1ohm. No one wants to be in the back seat of my ride lol and if i boom with the windows up they flex out past the rubber seals/trim. I can't see this setup blowing any time soon almost a year now and i go hard on them no mercy and still hits like new!

RF P3D4-15

i had one of these bad boys in a ported box hooked up to a old school Rockford Fosgate punch 200ix dsm amp hitting 139.3db it was straight slamming!!! all and all an excellent sub woofer i am in the process now of trying to get it into the trunk of my 95 trans am dont know how its gonna turn out due to very limited space!!!

Rockford Fosgate P3D4-15 (11P3D415) Review

It's a DVC, 15" Rockford Fosgate driver. It's what you would expect from RF. Hours upon hours of clear-cut, back-pounding bass. Anodized Aluminum cone has a different voicing to it than the old SPP cones I upgraded from. A great investment that will last a very, very long time.
