Punch P3SD4-8

The Rockford Fosgate P3S 8" shallow mount subwoofer delivers Punch, even in depth limited situations. Rockford Fosgate understands all vehicles are not the same, because some cannot accommodate deep subwoofers. In the past, that meant no Bass. Not anymore! Now even depth challenged vehicles can have REAL Bass and the Dual Voice Coil allow configurations for every application. Shallow woofers are specifically designed for spaces where a traditional woofer cannot be used.

2012 dodge ram 1500 w/alpine system

replaced factory sub with this RF sub in original factory plastic box and not much of a difference but you do hear more punch to it than the factory one. Powered by an alpine MRP-F300 is too much power for the RF sub , it starts to pop. Gain has to be set all the way down. Im going to power the sub with factory amp and use the alpine 4 channel amp to power all 4 door speakers see the results. Great sub though!

Tight Little Sub

I bought this sub to compliment my 6.5" comps up front in a big ole Tundra. I have 75 watts to the front stage and 250@ 2ohms to the sub in a sealed box. It's a perfect match. Nice full clean sound throughout the vehicle. I know 250watts is a bit high for this speaker,but it's in a sealed box and I listen to heavy music mostly, it handles it just fine. It feels great in your hands, solid construct. Very happy!!!!!

Not a bad sub

I have not had a sub any smaller than a 12" in the past, so I do not have a frame of reference for output of these subs. I have also never owned a Rockford Fosgate product. With all of that being said, I was very pleased right out of the box with the styling and sturdiness of the construction of the product. The dual voice coils provide a lot of flexibility with the wiring. I have two of these subs in a 0.45 sq ft enclosure with polyfil wired at a 4 ohm load and 150W per sub. They are not overpowering but are doing well so far.
