Question about Jl Audio 1000/1 Car Audio Amplifier
I had a JL Audio 1000/1 Class D amp driving a JL W7 13" Sub and never had the full power from my car to feed it probley so when turning the voulme up the amp used to switch off for 5sec and then back on and thats becouse of a low voltage going to the amp , So i've upgraded my battery to an optima battery and after 5min of listing to music on load volume it kepting switching off and then back on (same problem as before) then it just stop working..i've checked the power on the amp and it seems to ok as the lights on the LED is on. When i put my ear close to the sub i hear the music but very low and unclear and cracking noise. i've tried a different sub but same problem. i've took my amp to a repair centre but they couldn't fix it and they said to me that the power supply is working ok. the amp cost me alot of money and i really appreciate any help or if you could pin-point out the problem and i'll try to fix it myself as am good in electrnoics but but not the best. Kind Regards

I don't know if it's the same problem as yours but I have a 500/1 that after a few weeks decided to shut off by itself yet the power light remains on. If I cycle the power to it by removing the fuse I have right before it then putting it back in it will work for a short time then shut off again.
I have a thread about the problem over at DIYMA. Here is the link...

My amp did same shit, its the rca cabbles, check them out at the back of the head unit. the input jack is probably bad on the head unit

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.
