Check the resistance between the positive and negative terminals of the speakers. There should be atleast 1 ohm of reistance depending on your set up... if there is very little there is a short in your wiring. If not remove the wires from the amp and now check the resistance between the termanls on the amp...there should be no condinuity...if there is your amp has short circited out.

Assuming that you've confirmed that the speaker is in good working order and that the wiring isn't shorted in any way...

There are separate power supplies for the high and low amplifiers. It's possible that the one for the sub output has failed. If that's the case, the output transistors probably failed and that's what damaged the supply.

Generally, I'm willing to help people repair their amps but this is a large, complex amplifier and it should be repaired by a qualified technician.

SOURCE: jl audio 500/1 amp low ohm light at high volume

I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

I looked up the correct way to wire my JL 13.5W7 1.5. Therefore it said to wire it in parrallel. I understand this will put it at .75 ohm. As I start to turn it up it sounds great, very loud but once the...


1000/1v2 Class D Monoblock Subwoofer Amplifier Specifications:
  1000/1v2

Rated Power:
1000 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)

THD at Rated Power:
<0.05% @ 4 ohm

S/N Ratio:
>95dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)

Frequency Response:
5 Hz - 250 Hz (+0, -1dB)

Damping Factor:
>500 @ 4 ohm / 50 Hz


According to the chart your amp is only stable down to 1.5 Ohms, so running at .75 Ohms the noise you are hearing is the amp clipping (running more power than it can handle at low ohms)
I would suggest wiring it in series, or you could adjust the gain on the amp until the popping goes away.

Hope this helps.

When i turn the volume up my jl 1000/1 amp turns off then turns back on when the volume is low what can i do to fix this?


2 things, either your pushing too much power into the imputs (if using high inputs) and clipping the signal, or your running the ohms too low (lower then the amp can handle safely) by running multiple speakers of too low an ohm each. For example if your amp is 4 ohm stable and your running 2 4 ohm speakers in parallel that makes 2ohms and the amp can't handle a load that low. You can consult your manual and it will give you illistrations of wiring and ohm loads

Will a JL audio 1000/1 amp run a orion HCCA 15


Hello evopower,

The JL 1000/1 will power the Orion HCCA OK.

It is stable only to 1.5 ohms so your best choice would be the 15.4 with dual 4ohm voice coils. In parallel, this would offer a 2ohm impedance. The 15.2 could only be wired for either a 1ohm load (too low) or a 4ohm load (less power).

Hope this helps.
