Non I-Drive Audio Upgrade Opinions?

[ldireprophil]

I just bought a 2011 Coupe (No Nav or I-Drive) Wanting to keep the stock dash in tact, just really wanting to stream music. Don't need nav or back up camera. So this is what I'm looking at to accomplish this while also upgrading OEM speakers.

Denssion Gateway 500 BT (allows me to keep oem head unit while giving me the ability to stream music from my phone via bluetooth).

JL Audio XD700/5 amp

Focal 4" KHS speakers with component tweeters for side mirrors

Audion 5-channel digital processor

Gladen 8" under seat driver/passenger subwoofer

Just wanting some Feedback, comments, concerns? Thanks!

Check to see if Audion has a amp with a bluetooth in it. I added a rockford 3sixty and it allows me to stream music to it.
