Question about Jl Audio 13W7 Car Subwoofer
I got my 13w7 hooked up to a 500/1 amp for the time being till i can get the 1000/1 amp. But JL Audio's amps are complicated to get the specifice tone. What is the best settings to get the most out of my amp for my w7?
1. set the amp LP filter frequency at about 80hz and mode/slope to 24db.
2. set the amp gain as recommended in the manual.
3. set the subsonic to on and to about 25hz
4. ste the bass eq to off!
5. set the input voltage to low and signal sensing to off
6. Fine tune by ear.

Tips for a great answer:

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.
