I set out to resolve a rattle from the overhead speaker area but ended up upgrading the speakers whilst in there. I took plenty of photos and thought I’d do a write up, which may help others.
To access the speakers there are two T15 torx screws to remove, which can easily be seen when sitting in the back seat.
With both screws removed the speaker cover is removed by pulling it down firmly. In this picture you can see the location of the clips.
Removing the cover reveals the speakers and their mountings.
The speaker is held in place with four T15 torx screws.
To extract the speaker, removed all four screw and unplug the electrical connector by squeezing the catch and pulling.
For reference, here are some photos of my Twizy’s original speakers.
Unfortunately, although the original speakers are round and four inches in size the four mounting screws are not in a square (the hole centres on one side are ~81mm and ~93mm on the other).
I thought it unlikely to find some speakers, which were a direct fit so settled on a set of Pioneer speakers from Halfords. There was 20% off at the time so they cost me just £16.
After offering the new speakers up to the original brackets it became apparent new mounting holes would be required. To do this its easier to removed the speaker bracket, which is held in position with three T15 torx screws (note one of them is different).
Once extracted, remove the existing threaded screw clips before offering the new speaker up to the bracket, marking and drilling four new holes to suit and reusing the threaded clips.
To avoid any vibration I’d recommend carefully peeling the foam from the original speaker and fitting it between the new speaker and bracket before fixing it in place with the original screws.
Now for the electrical connection. I did a bit of research and found that when dealing with speakers the larger speaker terminal is usually positive and the wire with the stripe is usually negative. Also if you connect a 1.5 battery across the speaker terminals correctly the cone should move outwards. Based on this information I established the terminal closest to the clip of the Twizy’s connector is positive.
To avoid any confusion with this and to make things simpler you can buy a pair of adapter leads online for around £2.50. I was too impatient to wait so opted to cut the original connectors off then connect the leads supplied with the speaker using solder and heat shrink.
With the connection made I’d recommend wrapping the cables with fabric tape, to protect them from damage and avoid rattles.
With this done fasten the speaker and bracket back into position using the original screws.
Once both speakers are in place clip the cover back into position and refit the two screws. I applied some self adhesive padding to strategic locations to prevent rattles (my original issue).
I was happy with the end result. There’s not much change in terms of bass but everything else now has much better clarity. Also, the original rattle is now gone.
