08' 328xi Audio Upgrades
 

Just purchased a used 2008 328xi and would like to install a powered sub in the trunk. I have a Sound Ordinance 8" ported sub w/ built in amp. I don't want to make any major alterations to the vehicle and wasn't sure if it came with a preinstalled sub that I could run off of. Thanks in advance!

First thing to do identify which system you have L7 or Hi Fi in the US . non US could
be base also called stereo system. If all you want is a Sub Upgrade get in touch
with Technic for a Sub Harness adapter here or at the board listed.

Thanks for the info. New to forums/BMW ownership. I'll make sure to research before asking redundant questions.
