Nice speakers for the money those. I think you're in for a game to fit the mid bass unit though. I decided to leave mine factory because I couldn't be bothered to mess about. Let us know how you get on fitting them.
Got a bit distracted from the sump guard cause the new speakers arrived yesterday, so here is the 'HowTo'
First out with the old, as these speakers came with a separate tweeter and crossover box I had to cut the wires where the old ones joined. The old woofers and tweeters were wired in parallel so once cut the main feed wires were connected to the feed side of the crossover.
Then I looked at how to fit the new speakers and was pleasantly surprised they fit OK. That was until I lowered the window and found they fouled the glass coming down.
So after a bit of checking I came up with this.
A bit of plywood approx 10mm thick cut to size and drilled to suit. I had to drill the door skin too but that was easy then a few 25mm M4 stainless bolts and lock nuts.
I had to solder wires onto the woofer as I had no connectors the right size but I don't expect to ever use them anywhere else so not bothered. The wires then got connected to the output side of the crossover.
So with the woofer installed and connected it was time to look at the tweeter, the new tweeters came with nice cone shaped enclosures to surface mount them but I wanted the OEM look so I drilled a hole in the door at the correct height for the hole in the door trim and just jammed the new tweeter into it's holder. It should have fitted nicely but I didn't have the right size of drill to be able to use the correct screw.
It is taped on now too so should be fine.
As you can see the new tweeters came with connectors which just happened to fit the old speaker wires so I just reused them. I had to solder a bit more length onto the wires to get them down to the crossover.
This is it all connected up with the crossover wrapped up in cellophane and cable tied out of the way.
Once all connected I fitted a new membrane to the door
Had a wee listen and very pleased with the sound quality. The head unit is only a year or so old and reasonably good quality so getting half decent speakers makes it sound quite nice. Probably a lot better than OEM.
