Question about Jl Audio 13W7 Car Subwoofer
When they pop the low ohm light on the jl 1000 lights up I need to no how to wire them in series. I called Jl audio shop they told me and I wired how they said they still pop So what should I do to check them now I have a Optima battery to
Greetings I'm Ryan,
sounds like a clipping issue.
if you could please refer to you owners manual for the amp and sub and choose the best impeadance possible. i would recommend a 4 ohm load on those specific subs. but if you could either provide more info on the amp or check this link for wiring diagrams in how to raise the impeadance from whatever you have now to a 4 ohm load. which would be 8 ohm on each individual speaker then ran in series together

let me know if there is further assistance needed.

There should be no need for a series connection. The outputs on the amp are parallel inside the amp, requiring you to only connect the speakers separately to the amp. With two 4 ohm speakers, you will achieve a 2 ohm output [(4x4)/(4+4)] and be within tolerance.
The Low Ohm light will also illuminate in the event of a short. Check your speaker wiring, looking for any positive leads touching negative leads or for any leads that may be grounded to the chassis of the vehicle.

Tips for a great answer:
Jan 14, 2016 | Kicker Car Audio & Video
Mar 14, 2012 | Jl Audio Car Audio & Video
1000 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)
THD at Rated Power:
<0.05% @ 4 ohm
>95dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)
5 Hz - 250 Hz (+0, -1dB)
>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.
