The only thing that is not pretty straight forward in this is the parallel connection between the Front Doors and floors according to model year .
earlier than 2010 connections made in door sill for front speakers rather than at
the underseat speaker connector .
The other thing people have trouble with is coding to Hi Fi or not.
DSP's will take the place of eq flattening devices as long as they have enough
range.
The Base Guide is really well documented only thing is it uses pretty old equipment
and a eq flattening device.
Please read it.

There are many drop in speaker sets now pretty much all of them will be better than
stock. The MB quarts where on sale for awhile. I have seen people rave about
gladen/ mosconi setups . There use to be a shop outside of London that one gut was touting that sold this setup for around 750 lbs. I think it was called Monster Audio or something like that.
