please answer my question.

also is it the same for all speakers cutting in and out?

please and thank you.

 

It usualy breaks down to what is causing the speaker to cut out. It is usualy one of a couple things.
1. Wiring
A. look at the connections on the speaker. if they are on solid then move on to B
B. Either follow the wire from the speaker to the amp using an Voltmeter looking for shorts or just replace the line.
2. you could have a problem in the head unit itself or in an amplifier.
A. I would try rewiring the speaker first

 

I've got a problem with a 92 Transport. Front right speaker (top of the dashboard) appears to have a loose connection problem as it cuts in and out and crackles.

Was wondering what's the easiest way to get to the wiring connection.

TIA for any help.
