Really impressed with the write-up. No bull or pretending you know more than you do. Thanks. Just starting an upgrade now, thanks in part to your inspiration. Done a few in other cars, but wasn't so sure about the VE without having a manual.
Noticed though that in my SV6 the speakers are 4ohm, not 2. I think that'd be more of an issue putting 2ohm replacing 4ohm if the SV6 headunit isn't stable at that resistance. Not that it matters for me, especially as I'm replacing the headunit. An engineering company in Melbourne makes a new console that replaces the stock HVAC so you can put in a 2-din headunit. Doesn't arrive until Tues, so we'll see how complex that is to wire up. Admittedly I don't think it looks quite as good as stock (buttons only), but I can put in a new headunit of my choice. Mainly with pre-outs so I can properly also install my sub and amp I had in the VN.
Do a search for "ve fascia" and you'll find videos and various people who sell it.
So now to replace all the wiring for the speakers. Yikes. Only going to run the rear speakers off the h/u, amp for the sub and splits, but figure may as well replace those wires while the car is apart.
Calais57 - Look, I'm no expert. Far from it. But in my VN I made up some pods out of MDF, covered them in vinyl and just screwed them onto the door trim. Sort of in the map pockets (which I cut down). Sounds dodgy as, but I had no problems with them at all. For this car I think I'm just going to make spacer plates out of mdf and put a little padding between the mdf and the plastic pods. That way I wont have to trim them at all. Might ditch the plastic in the rear if space is an issue as that's pretty easy. However as the front isn't a flat surface, I am stumped as how to make them fit straight to the door. I have seen people use poly-pipe and expander-foam in days gone past. But that was more for speakers mounted onto the trim. Lets just hope there's enough room to the trim with spacers/adaptors (the splits came with adaptor plates, but the basket still hits).... btw- those adaptors that came with it are only 6mm plastic, so I guess you don't have to be very thick at all.
If only 6 1/2" meant the same for all brands. Geez, they even are different in the same brands. I have some old pioneer and sony that appear to be the same size as the stock. I know the Rockford Fosgate were larger in the old car. And now the new Alpine are also slightly larger.
