Hi guys, my kicker resolution crossovers have these bulbs in them, 2 bulbs in them.
I'm assuming 1 is for the tweeter and 1 is for the midrange ?
Is it still possible to blow a tweeter though with these crossovers ?

Also what should I have the tweeter attenuation set at ?

bulb don't prevent your speaker or in this case tweeter from blowing.

Well, I think you got a good answer over on DIYMA by reading the thread about it. Basically the bulb will absorb extra power, as it heats up more and glows more the resistance will rise more absorbing even more power. You can still blow the tweeters but this will make it much harder.

it is there to help obsorb DC current caused by clipping and to put some resistance on the line so you don't extremely over power the tweeter. it helps protect the tweeter but does not prevent them from being blown.

Clipping does not make DC, it is still AC, it just becomes very close to a square wave, but in no way is it DC.
