just finished installing Focal Access 165AS3 speakers yesterday on my 86.. its a complete drop in replacement of the OEM ones but the 86 came off the dealer with a decent HU already (Kenwood DPX5130BT) so it might be a little different if you have different HUs.. difference is very far from the stock ones and with what was spent, its a very nice upgrade
total amount spent is around $340 including labor, partial door deadening, and wires
front speakers
midrange and tweeter
partial door deadening
tuning it by my in-law
