I was initially running my CDT EF-61's on my jl 300/4 in four channel mode using an active crossover.
I recently bridged the amp to two channels and threw in my passive crossover so that i can get 150 watts per speaker instead of 75 watts. After that, i adjusted the gains and everything was fine for a day.
The next day, im driving and i notice that the driver side speaker isn't working...so i switch the balance over and my speaker sounds like it's blown...there's little murmurs comming through and some crackling at high notes.
I go into the trunk and see that the amp has an orange light on where it says "low ohmage"....the manual says that this could be a short in speaker wire or a blown speaker. I swithed the connections from left to right and right to left to see if it was the amp or the speaker, and all of the channels on the amp work perfectly fine.....so i know it's the speaker (i also took out the crossovers to eliminate them from the list of possible culprits, and the speaker still sounds blown).
I took off my door panel and checked my speaker...when i push in on the cone, it won't give....it feels firm as if the mechanical part is stuck. If i push in even harder, it barely compresses and as it slides back i can briefly hear music.
Is it blown? If it is, then that sucks cuz it's practically brand new and i don't think that i was even pushing it that hard...the only other thing i did prior to bridging the channels was set the lpf on the midranges to 3Khz.
