Because these PDX can be stacked what I did was just a plastic platform held by velcro to the OEM amp frame on one side and to the metal frame at the other end. The PDXs are just placed on top of the platform also with velcro.

Velcro allows moving the platform -and thus the PDX- for positioning and to access the wires/cables without any permanent changes/modifications.

I cannot PM you yet, and I do not do emails, sorry.

I do have the Logic7 harness available however it is not to replace the OEM amp. The harness is used to interface with the OEM amp outputs and speaker inputs.

Sure about the L1V2 together with the carbons?

I'm looking to replace it all together, but if my only option is to keep the amp, and use it's outputs summed together in the Audison processor and run back out to the Arc amplifiers then that is how i have to do it for now.

You need to either code that car to HiFi or get a mObridge DA1 with a bit one.1 to replace that OEM amp.

Wiring the OEM amp outputs to the bit Ten should work, although the woofer outputs max levels are too close to the bit Ten max input level.

The 2008 I have in the shop is the HiFi system already, which is what I need the harness for. The 2011 is not, but I already have a different route planned for the 2011.

A 2008 335i has a Logic7 system standard.

Sorry, you are correct. So if I recoded the deck to the hifi system it will work...

Correct, but you will need more than an OEM amp harness after coding.

Is this your first BMW with Logic7/Top HiFi system?

Yes it is. Is there a way I can call you versus writing everything on here that I can figure out what I need and give you money?

No calls, no emails... sorry. I'm not a business, this is a part time hobby for me.

Again, you need to use PM. This is not a classifieds thread and again I am not a vendor.

Quick dummy question on the install. How do you remove the housing for the speakers in the doors as I'm about to do the same? Do they just pop off do do you have to remove the whole door panel. Been a LONG time since i've done a stereo install.

You need to remove the door panels.

This is the EXACT system I would like to do, I've just purchased a 2008 with EPS. I've got the EPS system, so I need to code to HIFI and use your harness to go to MS8 and then aftermarket amp, do I have it correct?


Thanks,
Justin Wade
