2011 E92 Audio Upgrade - Trunk Subwoofer

I have read through a lot of info from the forums on audio upgrade. I came up with this plan based on all that i read.

2011 328xi coupe
hifi audio ( 4 speakers + 2 under seat subs)
I know i have a amp just not sure which model etc ( i will confirm before i purchase)
Audio will be from a android tablet or phone via 3.5mm audio ( bluetooth adapters quality just isnt that great)
I simply do not care for underseat subwoofers. My old car had a 12" sub with mbquart components, loved the sound from that system.

I repeat i do not care for the underseat subwoofer, i know pepole like them but i cannot stand them.http://www.m3post.com/forums/images/smilies/mad0260.gif


I just want a simple 4 speaker system with a sub in the trunk.

Upgrade Plan
Technic harness
JL Audio XD700/5v2 (same dimensions as XD600/6)
75 W x 4 @ 4 Ω + 300 W x 1 @ 2 Ω - 14.4V
http://www.jlaudio.com/xd700-5v2-car...plifiers-98606

QM200.3BMW - speakers only
Power Rating RMS 4 x 80 Watts
Impedance 4 Ohms

12W3v3-2Ω - subwoofer
haven't decided on a box yet, might get a corner fiberglass

Let me know what you think.

Wasn't sure I needed a lc2i, is that for the sub channel of for any channel to clean up the hu signal?

The hifi system does not require the LC2i as long as you use an amp that accepts balanced inputs. JL XD amps accept balanced inputs.
