L7 quit working???

[302yota 10+ year member]

one of my friends was riding down the road the other yesterday and all of the sudden his 15" L7 quit working....he's running it off of a hifonics titan 1500, in 4.4cubes at 34hz....(doubt that would have anything to do with it though)....he claims he didnt smell anything that would be burnt vcoils (although he doesnt know what they smell like)...and the sub stopped suddenly, it didnt just start making no weird noices.....i figured maybe he could have burned up the small guage wire that he has ran to his sub, or maybe the rca's came unplugged from the radio or amp...(because the amp is still on, with the green light on)....btw he bought his sub refurbished...What do yall think the problem is????

use a dmm

could be a bunch of things start by checking all the connectings (sub to amp and all that good stuff) also push on the cone and see if it sounds scratchy and feels weird thats usally a good sign its blown but not always.

wires inside the box coulda come out. put a multimeter to the terminals and if no ohm reading comes up, then that's the problem

couldnt i check the wires coming from the speaker ,(instead of the terminals), with a dmm?...and if it reads what it should, what else do you think could be wrong??

check to make sure your getting power to the amp then power to the sub if both are fine then he may very well have blown it

kicker is notorious for broken tinel leads i always had the prob with my solo barics and solo x

will the dmm show anything that would let me know if the tinsels are broken????

will the dmm show anything that would let me know if the tinsels are broken????

yea...it should either read 1 ohm, 4 ohm, 2 ohm, or 8 ohm....1 or 4 if it dual 2 and 2 or 8 if it is dual 4

you know that same thing happened to me with my d9s come to find out my rca's burnt out. try that out and see.

"Bender-Offender" are saying that it should read 2 or 8 ohm (btw is a d4ohm sub) if the tinsel lead are broke, or if they aren't broke???
