Default audiopipe 1551 blown..
looks like I blew one. I'm running 2 of these off a SD 250.2 on their own channel with the bass blockers installed. I had the gains set ~11:00.
any idea how it blew as they are rated at 250 max.
I need to know why it blew before I move up to more expensive horns.
any insight would be great. also, is there a repair kit I can purchase to rebuild it.
thanks

Don't care what the manufacture says. No bullet can handle 100+ watts of power.
Too much power...you blew the diaphragm.

11:00 on that SD is way too much. 9 o’clock is all they need.

Check the amp output with a meter to see how many watts you are feeding them. 11:00 means nothing. It all depends on input voltage and output wattage. Without metering you are pissing up a rope.

Hopefully you're wearing a mask while pissing!
