sub wont move in freeair, help?????

[mile098 10+ year member]

yes, i know but its not fried, hear this out.....its jbl p1222, dual 2 ohms...

i took a regular 1.5 v battery checked each coil separately it moves, parallel moves, series u hear the cabels thouching the poles but the bat is too weak to move it @ 4 ohms..

i hook it up to an ampRF bd1000.1(breaking in),and play pink noise...i feel the suspension vibrating under my finger, but no movement...started off low volume gradually got to 27 on 9855 and 3/4 gain on the amp...i hear the noise but it just wont ****ing move in series...tried it with music, and i hear it(other speakers disconnected) but the mother****er wont move...and in freeair at that much power the amp should have killed it....

btw the amp worked perfectly fine on my mb quart(unhooked it to break this one in)...WTF is wrong with it???and yes i did check the cabels, several times...plus/minus,plus/minus and in the terminal together...

pls help out:crap:

dont wanna try it in parallel cuz im not sure if the amp can take that load...

the sub is brand new

Did you check both coils with an ohmmeter to make sure you had the right resistance on the coils?

 

[mile098 10+ year member]

^^on my dmm i have settings for resistance in 2000k,200k,20 k,2000 and 200 ohms...i guess i set it to 200...where do i put the needls???just press it on the terminals or???

 

[pensacol 10+ year member]

Yeah set it to 200 and put the leads on the positive and negative terminals on the sub.

 

[mile098 10+ year member]

it shows 06.1

 

[mile098 10+ year member]

not ssure how to read the resistance, should it be this much, less more???

 

[mile098 10+ year member]

can someone tell me at least about this resistance, i dont know how to read it, but it strikes me as an odd figure

edit:2x2 ohms sub

Put your sub face down on a table and then take the measurement of one coil with your meter leaving the other unconnected. Try not to press on the terminals - any movement of the sub will cause the reading to go off. Polarity does not matter with DC resistance tests, which is what you are doing.

Then do the second coil.

For "dual 2 Ohm' subs you should get a reading anywhere from ~1 - 2 Ohms per coil.

How exactly do you have your sub wired? Like name which wires are going where.

 

[pensacol 10+ year member]

If the coils are 2 ohms, and he's getting a reading of 6 ohms, something's wrong.

thats for sure.

did you try putting each coil on the amp at a time for a short period?

then just wire them in parallel and then series.

might be doing it wrong.

They could read high.

I think there might be a wiring issue.
