The box was built today, 4.27 cubes @27hz.

Now I disconnected my current sub JBL 12" which was wired at 3ohms and connected the Fi Q at 1 ohm. IT DOESNT POWER ON.

The amp is an Elemental Designs NINe.1

Before you say the fuses are blown, I wired correctly to 1 ohm, put the JBL back in and it worked fine.

What could be the problem?

make sure all the connections inside the box are tight. if theres a connection that has come loose somewhere between the amp and sub then it wont play at all.

3 ohms?! WTF coils does that sub have SVC? DVC?


Now onto the Q, what coils does that have, and how did you wire it.

Alright, the JBL is dual 6, and Q is dual 2.

The amp powers on, the connections have to be tight because after the Q didnt work i hooked up the JBL and it played.

I wired + to left + and - to right -

you used all the same wires to hook up the JBL as you used to hook up the Q?

You say the amp doesn't turn on when the Q is hooked up?!!!!!

Or does it turn on and just not play?

idk that doesnt sound good. if the JBL works and the Q doesnt and all of the wiring is set up right there might be something wrong with the sub. email or call scott tomarrow or hope he see's this thread and mabey he can give u some info

I had a couple friends check it out, JBL works perfectly, when I wire the sub correctly and turn it on I get no response.

Don't go jumping to conclusions about the sub being the problem.


Mike, use a DMM to measure the resistance (ohms) across the amp's speaker + and - terminals with the sub hooked up (and the system off). You should get ~1 ohm (you won't get exactly that). If you get some really low number, you have a short somewhere.

Oh wait, didn't see the part about same wires. when you say same wires does that mean you are disconnecting the wires from the JBL subs terminals and connecting them to the Q's terminals? And not touching anything else? If that's the case, then the wiring is good.



Use the DMM to measure resistance across both the subs coils. They should each be ~2 ohms. In order to cause this condition when wired in parallel, BOTH coils would have to be bad, which is highly unlikely. But check it anyways.

Yes, I am disconnecting from the JBL then connecting to the Q and i get nothing.

I don't know anything about the tinsel leads anyway haha.

Ill take it to an audio shop tomorrow and get it checked out I guess

try wiring the Q in a series... the exact resistance is 1.5ohms so ur giving it .75 ohms in reality, which might be the cause.. if it works when you wire it in a series then the resistance is too low.

The red arrow points to the tinsel leads check and see if they arent connected.

Scott told me the NINe.1 is fine

"The NINe.1 should be a good match, but be sure to get the subsonic filter setup correctly (about 25Hz)"

Ill check the leads tomorrow its too dark out right now.

Check your sub's coils with a DMM like I said

If there is something wrong with the sub's coil causing an open circuit, he will not get a reading on the DMM. Believe it or not I do have a reason for telling him to check that......

No number to reach me... but thats why I check here at least once a day :-)

Id say you need to do a pop test on the coils to make sure that the polarity is correct. Take a 9v battery, your cars battery, the 18V battery out of your Makita... and put a wire from + of one terminal to the + of the battery, then the - from one terminal to quickly touch the - of the battery. This should pop things in the outward direction. Then do the same for the other coil. If it pops in the wrong direction, then check to make sure the terminals are facing the correct direction or that the little colored (red and black) bands are on the correct + and - of the terminal. DO NOT let the battery sit connected to the sub. It can make things mad...

Once it is determined that both coils work, then hook up the + of each coil to the + of the wires that go to the amp, and the - of each coil to the - of the wires that go to the amp. Pop test again to make sure that it moves in the same direction (you always need to pay attention to polarity). If not, reverse the + and - on one coil and see if it works...

Sounds to me as if it is simply wired out of phase some how.

Thanks,
Scott

Scott I understand you trying to help, but I have no experience at all with Car Audio and would not be able to do that.

I will take it to a shop and have it metered with a DMM, if its not wiring, I will send it back since there would obviously be a problem with the sub that I myself cannot fix or test without creating a worse problem.

That's a big problem right there :-( Keep on reading and hopefully, you'll keep on learning.

Mike... Id bet you $5 that you could do it. (chance of winning $5 and saving the cost of a trip to the car audio shop).

This one is really easy to do, and if you email me Ill give you my cell so that I can walk you through it. Scott@FiCarAudio.com

Thanks,
Scott

I went to Walmart after school and bought a pack of 9v batteries, $5.68 and waited for your e-mail back that I sent at around 1:00 this afternoon.

I scheduled an appointment at Sound Fx tomorrow for them to check it out, another $35.00 minimum charge.
