Hi, so my driver side OEM speakers are cutting in and out with the sound. Usually when i slow down the sound comes back for a bit but then cuts out again. I thought maybe it was a loose wire and called up a local custom audio shop about repairs. They said it's near impossible for the wire to come loose because the way that its connected to the speakers by Infiniti. He said he's 99% sure the speaker itself is the problem.

Is this true? Any Infiniti techs that can vouch for this? Just want to make sure he isnt just saying that to upsell and make me buy new speakers and spend more money.

 

It could be this:

Speakers are moving electro-mechanical bits, so they can fail over time, but cutting in/out usually isn't a speaker going. Getting noise on them or getting quieter is more typical of speaker failure.

The factory headunit has a failure rate several orders of magnitude above the speakers, so it's the first thing I'd start to blame.
