Hello gents,

I'm guessing this is redundant, but I'm having a hard time muddling through all of the variants in our stereos. I'm hoping you guys can clear some things up for me.

I have a 2010 E92 base stereo, and am planning to upgrade the front stage, and add a sub in the trunk. I wrote Technic regarding harnesses, but it seems he doesn't make a sub harness. I'm wondering if I can recode the HU to hifi and then grab the rear speaker signal to run the sub? How can I tell if my HU is one that will accept the recode?

Thanks for the insight!

so from what i understand your headunit will recode to hifi but you will need an amp to power all channels at that point (front and rear)

Also, IIRC you cannot tap the rear speaker leads for the subs.

I'm sure that others will chime in here, but first check the stickies here - you're not the first to head down this path...

If you just want to add a sub to your Stereo system then tap the woofer wires under the seats with a 2-ch LOC. Pin 2 is negative, pin 3 is positive.

That's it.

Thanks for the help. Technic, I'll be in touch in the coming days to purchase a harness. I just need to get my mind around what I want to do with the cabin.

Thanks again!
