RF Subwoofer Question..Please help !

[04blkse4x4]

Hi Guys,

I would like to know a little about the RF subwoofers that come with the RF package. What size subwoofer/speaker is in the enclosure? Can we replace the stock sub/speaker with an aftermarket sub ( 8" ) ? The reason why I am asking this is I know someone who is selling their RF sub with the enclosure. I was wondering if that would be a good buy. If not for the sub, atleast the enclosure to go under the driver's seat. Also does anyone happen to know what the specs are on the rf subwoofer ? Will it work fine with an aftermarket amplifier ? Any help will be greatly appreciated guys !! Thank you !

Sang.

In my 2004 it was a single Rockford Foster (not Fosgate) in a shallow plastic box under the driver's seat. I gave away my RF sub & enclosure, so you can deduce my assessment of its value.
