I'm hoping to get mine finished next month, spent months on it in between shifts when I first bought the car, ripped he interior out and deadened everywhere!! But haven't touched it in ages. The standard systems awful (and I'm one of the lucky ones with the full speaker set up!!) very difficult to upgrade on the 03-06 cars, 07 onwards has a normal double din unit so piece of cake to just swap for a good one and wire up some amps/speakers
So far I've deadened all doors with CLD, CCF & MLV. Same as the floor (took AGES!!!!) so just the boot & roof to do. Deadened the rear shelf a lot and it's helped get a nice tight bass from the 6x9 subs.
Single Din Headunits been fitted instead of the old CD player and entire systems been bypassed as its a fibre optic one (cheers SAAB....appreciate it!!!!!!) So will eventually be running an independent 4 way active SQ set up (3 ways up front & the 6x9 subs in the shelf)
Head Unit- Pioneer DEX-P99RS
Speakers- Sinfoni S Series
Subs- Genesis P69
Amps- Mix of old 90's Caliber Evolution, Denon DCA-800 and RF Punch
Wiring- Mix of Knukonceptz & Van-Damn stuff
Deadening- Silent coat
Should sound good when I get round to finishing it!!!! Keep finding excuses not to!
