Important information concerning your choice of speakers
The larger box is actually quite shallow so try to get shallow speakers.
The depth at the shallowest point is only about 45mm so be careful.
Some people have made spacer rings from MDF which resolves the depth issue.
Fitting
With the dash off you will find the speakers screwed to the underside of the dash, remove both of them and throw them straight in the bin (burn them for being so rubbish).
Fix the spade connectors and wires to your new speakers and screw your new 13cm speakers into the new boxes. Route the wires out of the provided holes.
Fit your speakers tightly into the speaker boxes.
This is the top of the fuse box under the dash on the left hand side, circled is a 6mm bolt that helps to fix the box down. Add a washer to it first and tighten it right up.
Put the larger box in place and line up the 3 fixing points.
1 screw in here just behind the airbag.
One screw off to the left of the box.
Make sure this tag is hooked over the thread, fix down with a 6mm nut and washer.
This shows you the location of the 3 fixing points.
This shows the space on the right side, again the 6mm thread is highlighted.
Drop the smaller box into the hole and line up the 3 fixing points,
fix with a 6mm nyloc nut and washer here.
One screw to the left, next to the steering column.
And one screw on the far right hand side.
This shows the 3 fixing points of the right box.
Take a look on the front edge of the dash, you may up to 3 clips,
or they may still be attached to the front of the car (circled).
Place all the clips from the dash back on the tridion at the front of the car,
it makes it easier to get the dash back.
Fix your tweeters to wherever you want them (usually on the dash), run the wires down to the stereo and zip tie them down to stop them moving about.
OK, the tricky part. Put the dash back in but slightly too high so it sits further back.
Very slowly move it to you until it suddenly drops down about 10mm, get out of the car and look in the windscreen to make sure the dash is sitting central by lining it up with the windscreen washer jet. Once it is central give the dash a shove on both sides at the same time, if done correctly it will pop into place.
If not, recheck the position and try to work it in from one side to the other,
you may need help from a friend if you have any.
Wiring the tweeters into the stereo
Have a look at the wiring diagram of the stereo
Activating the sound upgrade
If you have the radio or cassette stereo make sure you have the sound upgrade chip installed in it. The chip is pushed into the top of the stereo . There is a removable cover. Have a look
The CD stereo already comes with an integrated chip.
Press and hold the music symbol button whilst turning the unit on.
Continue to hold the music button until SOUND ON or OFF is displayed.
Repeat to toggle the feature. Obviously you want 'sound on'.
