My old 100HP had the factory sub and I liked it.

The 500 subwoofer comes up on ebay all the time and it's a different part number, but it looks identical to me.

The wiring is allegedly under the drivers seat already. (Whether it's only the 6 speaker or all models I don't know)

What's the chances of it being plug and play?

Will it work with the non mp3 radio?

:slayer:

My 100HP (07) has no sub and no wiring under the seats.

The wiring is buried under carpets... should it be there.

Fair enough but your image just shows the bare floor (with anti vibe pads). I've had the seats out of my 100HP. The only boxes of any size are the floor cross beams. No signs of a speaker sub.
