No matter what I try I cannot get the front speakers to work. The Mini came with no radio but rear speakers, and front speakers and tweeters wired in together. The rear speakers work but I cannot get the front speakers or tweeters to do anything, however when I attached a front speaker to the rear speaker wire in my Viva it worked. So I'm a little lost. Is there meant to be something additional in the circuit to run the front speakers and tweeters or should the be able to run off the HU?

they should be able to run off the headunit. There should be 8 wires total (4 for rear speakers, and 4 for front speakers).

Have you tried connecting the rear speakers to the front? If wiring isnt the problem, there might be a blown fuse in the head unit!

This has been the same case for 2 or 3 fully working HUs. I'll be honest I've not tried running them on the terminals for the rears. Good idea and I'll give it a go. But then it seems odd for the front speaker terminals on several HUs to be broken.

The way the PO wired it, the positive wires from the front speaker and tweeter go into one spade connector, and the negative of both go to a spade. Is it ok for them to be wired in like this? I don't have any experience with tweeters.

like this?


ignore that fact the digram shows subwoofers.

If that is the way it wired then the load on the HU will be 2ohm. it might not be able to handle this low ohmage. But if this was the problem i would expect the speakers/HU to work at low volumes then 'give up' at higher volume.

Also there should be a capacitor in + feed to the tweeters otherwise they will be playing full range.

Have you tried running new cable to the speakers? or even other speakers as a test?

[oli8925]

Yep, like that. I haven't tried other wire or speakers, I've only just had the chance to take the dash out and sort some other gremlins. Should I get it working, what value capacitor should I use? I can't find a model number on them but they are very ordinary looking Sony tweeters like these. Best I can do at the moment.

Have also just tried connecting them to the rear speaker terminal but they still don't work. Will try new wiring when I get time in the week.

A 10uf Cap will cross out everything below 4000hz (ish)

wire them like this.

Here is what you need.

item code, VM93B

But have a good look at the tweeters before you order anything, they might have something as standard built in.

Get me the model number and i'll try and check for you.

Can't find any model numbers on the tweeters for the life of me.

can you take a pic and post that up?

[luvlygal]

Dont think this is close enough but it was one I already had on my PC. Let me know - I can go out and take another one

LOL

i was hoping for one of the back...

are they stuck in place ?

[luvlygal]

Should've said - you have to be specific, you're talking to a girl!

Yeah, they're stuck down... well, this one was before I pulled it off this morning trying to find a number!

[pbrain]

i would pull the existing ICE wiring out and put a new set in, there could be a fault which may damage your head unit after a while. Can't beat a fresh clean install!

Also i prefer to use 4.7uF down to 2.2uF bipolar caps (the lower the value, the higher the frequency crossing...on my PA cabs i have some JBL tweeters with 1uF caps...really tingly!)
