I have all my equipment ready for the 08 35 im about to pick up. My only concern now is to find a way to control my amps. Im going to bypass the bse amp totally and replacing all the speakers in the car. Now my question is how is the qaulity of the signal coming out of the bose headunit? I love having control of the x-over freq's and what not, so i need to know if i need something like a jl cleansweep, or simply a something like an audiocontrol lc7 which is just a x-over with seperate front rear and sub controls with 8v output to the rcas? Is the signal coming out the headunit flat and clean? Or is it only equalized from the bose amp itself?

 

In the first generation G's, the audio signal from the Bose HU (actually made by Clarion) was pretty flat and wasn't too bad. The Bose amp is the terrible piece.

Unfortunately, I don't know anything about the 08 system.

 

I have an 07 Sedan and I am deciding which way to go also. I love the way that the stock headunit works and integrates with everything so I dont want to loose it but I do want a lot better sound. My 2004 Mustang with the Mach system sounded better. I am going to remove all of the stock system except the headunit and go with the Rockford Fosgate 360 interface, love the bluetooth control that it has for the EQ and setup programming, Kicker ZX460 4 channel amp, Infinity Kappa 50.7CS component speaker front and Infiniti Kappa 60.7CS Component speakers rear, and a Rockford Fosgate Power 360.2 pushing a Kicker Solobaric L5 10". I looked at the JL Cleansweep but liked the Fosgate unit better, I have a PDA cell phone and can control everything right off of it.

 

I went with a Rockford 3sixty.2. I was looking athe cleansweep, but it only offers front and rear outs and you would need another device to sum a sub output. Where as the rockford has 6 output channels, as well as a lot more tuning capaibilities.
