one of my rear parcel shelf infinity's is crackling does this mean i've blown it up and have to buy a new one!

 

Check connections first. Check there's nothing physically in the cone or on the spider (stupid as it sounds, seen that happen...)

After that, GENTLY push the cone in a straight line (DON'T rip it off the spider). If things don't feel smooth then there's a good chance you've buggered it and, yes, you'll need a new unit. It's probably under-amplification that will have fried it with an unhealthy bout of DC current so do one of two things: filter low frequencies out of the new one, or get a decent amp.

Hope you haven't knackered it.

Nick.

 

oh thank you, i will check this out and report back

 

ahem yes, the cone is ripped up badly. only one parcel shelf speaker. i was fiddling the other day! oh oh i need new ones.
