Removed the stocked sub and replaced with a Rockford Fosgate P3 and a ported box powered by a ZX500 Kicker Amp and LC2i Audio control the sound system now is rocking the boat......lol, I don't use the trunk much so space wasn't an issue for me.

Picking up the grill tomorrow they didn't have one in stock.

Wow - that's a monster sub! The width looks like a custom fit for the A7. I bet it sounds great.

I did a similar upgrade a few months ago but used a much smaller JL Audio sub - so I could still easily fit a pair of golf bags in the back. Also used a JL Audi sub amp and LC2i. Love it.

Can some one tell me if you tapped into the rears or just used the existing sub connection? I am reading that there are some good results tapping into the rears, i guess that you get more control of the signal coming in. Just not sure how to tap into the rear speakers without messing up their signal.

Any and all help is appreciated!
