Ticking / Buzzing Speaker! What The? Help!

[nuffsaid]

Hi all

One of my 5" 2 way speakers for the back has a ticking or constant buzz buzz buzz .. sound.

It started off being a once in a while thing, then progressively got worse, now it just ticks all the damn time, and its just one of the speakers.

I removed the connection from the amp to that problematic speaker and the buzz is gone so its either:

1) the speaker is gone!

2) that particular channel of the amp is stuffed

Amp is an Alpine V12 4 channel.

I should have tested that channel on another speaker, or powered that speaker on another amp, but forgot.

Can amps have one faulty channel? or is it safe to say the speaker has crapped itself?

Thanks very much!

go back a few steps and refit that amp. from there swap channels around and see if it follows
