So is this where our Subject Matter Experts are positioned at the moment for 2011 E90 base audio systems, either:
1. DSP+Front speakers+underseat subs+rears speakers
or
2. Recode to HiFi+Front speakers+subs+rears (with this option still suspect)
How do you determine ranges of systems i.e. budget, mid-range, high-end system...quality of hardware alone or additional replacements of OEM hardware?
