    In my R/T Classic it came with the 7-Speaker Boston Acoustic system with upgraded amp
    I found out that the subwoofer was crackling when I turned up the bass, so I decided to replace it with a Rockford Fosgate P|2 8" Subwoofer
    Despite reading that a lot of speakers don't fit, I was able to make it fit without modifying anything
    It was a very tight fit but it eventually went in and the rear deck cover is as flush as before, maybe bulged up 1/4" at most in the far back against the glass
    I cut off the stock connector and hard wired the Sub in
    It sounds great, although people said it wouldn't produce more bass and it was a waste of time, it sounds much better than stock did
    Of course it'd sound even better if it was enclosed but I liked not compromising any space in the vehicle to install it
    Hope this helps anyone wanting to install one into the stock hole!

    Great info. I'm trying to put a decent sound back into my 2012 Challenger R/T with the same (original) package. A previous owner replaced the HU (Kenwood DNX570HD), replaced rear deck speakers (Hertz 165.5), bypassed/disconnected the factory amp, cut wires (appears the speakers are run from the HU), didn't connect the door speakers, took out the factory sub, added a sub and amp. Prior to selling the car (to a dealer) the aftermarket sub and amp were removed. The RCA signal cables (and a third wire, presumed to be remote turn on) were left cut off in the trunk.

    It's great to know what size factory sub was used and what my options are should I want to use the original install spot.

    Got a question about the RF subwoofer - is it a single or dual voice coil, and how is it wired?
