What not to do when installing speakers!

Car comes in for a set of speakers, i rip the door trims off and find a set of Alpine Type R Component speakers....wow, he's done well to blow them i thought.....Then i took a closer look:

First mistake, obviously water is leaking into the door, the fitter / owner would have noticed this and did nothing to find or stop the leak, instead they decided to make a new mounting plate from BARE MDF, and we all know what MDF does when it gets wet:

Sure enough, the back of the woofer was worse:

Finally, the reason why they stopped working.....

So, two lessons to learn from this:

* Find and fix any leaks in your doors if theres evidence of water inside the door cavity. It may be an easy fix, it may require a new window seal.....but if your going to be putting $300+ speakers in there (like these Alpine Type Rs) then its money well spent.

* ALWAYS paint MDF, speaking from experience it is very porous.....soaking up anything really. This can dramatically reduce the strength of the wood and cause leaks or the speaker to fall out!

Found pix of a Canadian slap-job install..

Just run the cable under the cowl, down the door jam, into the kickpanel


Shove the ring under the battery terminal and get plenty of air into the connection, then drag the cable over the intake pipes. :rock:

That mdf looks pretty shocking.
Back of the magnet edge looks like it had a few winters in the door.
Sometimes a speaker cowling is needed above the speaker to stop drops of water going into the inner working of the speaker.
I made some for my morels out of fear and realized its a good idea anyway.

Zion, exactly.....it dosent take much to wip up a small rain shield to cover the magnet if your suspicious of water getting in.

Actually, after i replaced the speakers, the customer actually wanted them back! Well that was until they saw them :laugh:
