w7 and 1000/1 problem

[xtremebassjunky 10+ year member]

originally they were wired for .75 per sub (thinking that impedance rise would get it above 1 ohm) but was informed that that was wrong and they need to be wired to 3 ohms per sub. thing is, we listened to them after we rewired them and could tell that they were still playing, only not as loud bc they are at 3ohms vs .75

why didn't you just check to see if you were getting 1 ohm with box rise?

you would probably be at 1 ohm or higher I would imagine with rise...

hmm RIPS should've prevented that..but then again the 1000/1 is made for 1.5 -4 ohms, so if they were playing again after you rewired them when did you arc them on your arm?

1 ohm is no good for the 1000/1... its 1.5ohms... 1 ohm makes it shut down or over-heat

we werent beating hard on them at .75 so thats why it didnt shut down. arc'd my arm after the impedance switch

ahh... I really don't know jl amps...

I do know I think there are more controls on it than necessary, for a lot of the people who buy it. most people just jump on the bandwagon...

as far as things are concerned though with variables affecting it... it is possible to see close to 1.5 ohms with rise...

I have a buddy who we set his stuff to .5 ohms and with rise we saw 1.1...

so it all depends...

also what's the JL's efficiency rating? I have heard in low to mid 60's which is bad news for a class d....

why was the speaker wire laying around for this to happen?

setting the gains with dmm and tones

lol... thanks for that...

THAT i don't know but it cain't be too high, that thing can get hot as ****

even just beating softly, they were warmer then what my bx2005d got at full tilt at 1 ohm...

 

[xtremebassjunky 10+ year member]

Like I said.. one of teammates said low to mid 60's and then when you crank the gain on it you get even less efficiency on it...by like 10%...

hes gonna take it to the shop tomorrow to see if they can figure it out by just lookin at the amps (see if the settings are off or soemthin)
