Hello everyone.

I'm in the final stages of upgrading my 2008 E90 base stereo. Got my spacers from JTSherri and harness from Technic coming.

I need to choose a DSP. I'm thinking of these options:

a) Buy a Helix P-DSP and leave all the factory speakers.

b) Buy a Bit One-D and leave all the factory speakers.

C) Buy a Bit One and upgrade only the front speakers. (Focal)

I'm thinking of doing the under seat woofers last.

A,B, and C options are about the same price in Japan.


Any advice or ideas will be greatly appreciated!

Thanks guys!

Alpine H800?

Why would you consider adding an expensive processor and then being cheap and using crappy stock speakers? Especially since you have the base system.
