[QUOTE="Lisa Lane-Collins, post: 7045, member: 2967"] working with passive speakers for the first time. paired 4 peavey f1 subs with a lab gruppen fp3400, two a side, linked together using the input/throughputs on the back of the subs. am using a dbx drive rack to cross over, and powered jblprx615s on top (the four peaveys blow them out of the water, wicked). so i powered every thing up, wound the amps back to half to try and bring the jbls and sub volumes closer together, played a bit of edm through at ball park gig volume. heard a few unsettling crackles, then a pop, then i lost a side (just as i was reaching to wind the amp down). now one sub is dead, judging by the acrid smell, i may have burnt out a voice coil? oh well, they were ten dollars each, my question is, what can i do to safeguard the remaining three against a similar fate? also, is it possible my very average soldering job on the link cables is what is creating the pops? and can those pops be lethal? show time is in 14 hours, super looking forward to reading peoples replies. thank you :-) [/QUOTE]
