Nice. How much did it improve your audio experience?
And could you share some installation details what we need to care of or what general trouble could appear?

Looks good. I’m just about to do do mine, apparently the rear speaker output from the head unit is low-pass filtered only so just a mid drive without tweeter will be OK (I’ll test when installed) I’ll get on with my install when it stops raining here ? and post up the results.

….. did you fit the passive crossover for the front speakers? It is needed for the tweeter to work properly

Got a professional to do mine, improvement to the midrange well worth the £300

The sound is much improved, much better bass notes with good punch and clarity, mids have better clarity and better control, the best upgrade though is with the tweeters: highs especially percussion and vocals really shine. The sound deadening is very important so don’t miss this out it’s well worth the extra control you get over the low range.

Hello,
Are the rear speakers really filtered low by the amplifier?

Merci par avance

I tested with a full range sound test track and the rear output was full range, didn’t seem to be filtered (UK long range Trophy)

Thank you very much.
I'm going to put my coaxial focal kit on the back.
I just need to find out how to connect the active filter box for the front exploded kit now.
