Can the bimmertech amp be used to power standalone sub as well

IWantAnE92 · 08-16-2017, 04:46 PM

Hey,

I have the Bimmertech amp which is driving the speakers in my M3. If I get a trunk sub as well, are there enough channels on the PP to drive the sub or would I need another amp to drive that?

TIA

Can anyone shed some light on this please?

Well if you buy the Helix 82dsp and or download the manual
it says the factory version will allow you to assign 4 channels
to a sub which gives you 200 watts I believe. But the Bimmertech
harness may not be layed out to do that. So you would have to talk to
them for clarification. I believe they only use 6 channels out of the
8 also. 100 or 200 watts doesn't seem to be enough for a proper sub.

The Bimmertech amp is the Helix 82dsp that they
have customized by Helix to run on low level inputs.
The minimum I would think about is 300.

Depends on the sub, your output desires and what you want to give up- the amp is currently running 7 channels so lose center channel and then you have two remaining. Something like a reconfigured PP8E would work fine from this (just as an example).
