I believe you have a weak ground signal. Check the ground location.
Unhook the power fuse from the battery. Remove the ground, peel off the paint behind the bolt and scrape the copper off the back of the connector as well. You want metal to metal basically. Put back in the fuse.

Could also be incorrect wiring to the subs and amp.
Has the amp ever been hooked up before?

Have 2004 Toyota RAV4....installed new double din stereo radio....unit powers on can change stations...indication that sound is coming through the radio but I get no sound

If your RAV4 originally had a JBL radio, the steering wheel has provisions for control of amplifier volume. The JBL also has a MUTE output which may be preventing the amplifier from turning on.

I have a JBL S120PII sub that stopped working. All I get is the red and green light flashing on top. Is this indicative of a specific issue?

Check and replace the power output MOSFETs [at the power amplifier circuit]. A damaged MOSFET can cause this continuous LED blinks. It is important to replace all the 4 MOSFETs at one time. Also, check for any further damaged to any other components too have occurred. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

Power light flashing

If the power light is blinking, your unit has DC Offset, meaning an amplifier is damaged. For more information, please visit my website at Thank you.

Ok i got a jbl gts 180 amp for my car. after i hooked it all up and turn my car on the power light stays on but it dosent push my subs. It will hit for 1 sec then stop with the light on. I have had it...

I repair car amps for a living and my prices are the chepest in the USA if an amp needs to be sent to me, plus shipping. I get a lot of amps to repair from this site. Sound like you might have to low of an ohms issue. If not I would have to have to look at it. I don't charge a bench fee and give a 90 warranty. I have the same amp in my collection. My prices also rarely exceed $60 to $80, something like yours would be around $40 or $50 plus shipping if you need to ship it to me. I have been doing this for 17 years and have'nt ha a complaint once. I also fix things in amps I see that might need fixing for free. People ask me why I do'nt charge more or fix things for free, is because I'm not hard up for money and I want to help my fellow car audio enthusiests. Let me know if you need my haelp. I will try to help you online first before we need to go further.

Btw, I’m available to help over the phone in case u need at

JBL amp, worked fine untill 2 days ago. protection light on..

might have roasted your speakers voice coils a little which may be sending the amp into protect mode throw a speaker on it that you know works and if it doesnt trigger the protect circuit then you probably have a blown or almost sub.
