Is there a green light? does it go red? the unit could be auto-protecting from your speakers, are they old speakers?

Low ohms light flashes and bass distorts at high volume


Sounds like you need to invest in a capacitor. Those are used when subs receive a bass spike. You just a need a 1 Farat Capacitor (1,000 watts) ran between the head unit and the amplfiier to fix your issue. Also, try reducing the volume gain to half gain and low pass frequency to half gain; this will increase your clarity and make your amp less hot. This may fix it without a capacitor. Also find out what amprage your alternator is. Your alternator may not be designed to run the amplifier. Most alternators are 200 amps now if they are gold plated.

Hope this helps

Jl audio 500/1 problem


Usually all amps spark a little when hooked up again after a while of no use. this happen cause there are many little capacitors inside to keep the amp running when hitting long bass notes. I think the reason you have been having problem after replacing the transistors is because there not the rite model number or maybe the polarity. You mite have to call jl and ask them if they have any in stock or google the model number of the transistor and buy them and replace them and see if it work. if it doesnt work then it mite be something else inside.

Sounds like you fried the channel on the amp or your gain might be up to high for the speaker

Amp settings


It's going to be mainly "what sounds best", but I'll give you a start.
  • Set the gain to 50%.
  • Set the LP filter to 12db at about 80Hz.
  • Set the infrasonic filter to ON and at about 20Hz.
  • Set the Bass EQ to ON, Q to 0.7, center freq to 40Hz, and boost to about 5dB.
The other settings are going to be based on how the system is connected to the head unit.

Blowing fuses


You will need to have the amp bench tested at full load to see if there is a pending problem. It will need to see with speaker loading resistors, how much current the amp is drawing and at different frequencies. if the amp checks out with the proper current, at the rated output, have the speaker checked out. Good Luck
