Yup. Remember the F30 HK system is quite a bit different/better than what's in the E9x cars.

The HK could be upgraded for about $1100 in parts and coding (it has to be coded back to HiFi, otherwise there is an extra $700 expense just to replace the OEM amp), because those 7ohms underseat woofers must be replaced.
Believe it or not, I can tell the loss of amplifier power in the F30 HK, vs the EPS in M3. The midbass loses control lower in the volume range, and everything else starts falling apart at higher levels.

I'd be more interested in improving the amp, vs. "more bass". The mids have a fairly neutral quality to them.

Is there another thread we should be discussing this on??
