Question about Boss GT980 Car Audio Amplifier

Can't get the amp power on

I turn on my car and the amp goes to "protect" which is red instead of "power" which is green and turns it on. I've checked the ground wire and its functional and working. The power cable is connected and has all new fuses as does the amp. So i can't figure out why the amp won't power on. If you could help me i would greatly appreciate it!

Re: Can't get the amp power on

Hi, by design the protect mode is activated if it senses a fault in the system which can either be: speaker problem - check the speakers connected to the amp. also check that the speaker wires are not (scraped) rubbing to the car body. On the speakers themselves, using a continuity tester (better with a VOM) should indicate anywhere from 4 to 8 ohms on the terminals. In the absence of a continuity tester, a single AA battery will do to check if the cone/coil will move if the AA battery power is applied to the speaker terminal (this is not a sound practice but in the absence of a tester only). If the reading is either 0 ohms or infinity (no reading) or no movement (if using the battery method), then the speaker(s) need replacement. Amplifier problem - this is identical to the problem and possible solution at Good luck and hope this be of some help. Pls post again how things turn up. Kind regards.

My kicker amp goes in and out of protection, like when i turn the car on it turns on green then just goes red then goes to green again and goes back to red. I was bumping for awhile and just started hear...

Thankyou for the detailed fault really helps!

sounds like there is one of these 3 things wrong:

1. leaky or partially blown mosfets on ouput power stage of amplifier are leaking DC onto speaker output causing amp to go into protect..this explains any banging or clicking herd.

2. There has been damage to the internal SMPS and is going into protect because of an internal rail over-voltage/under-voltage.

or 3. you have a shorted speaker lead or sub that is bringing the amplifiers load down to less than 2 or obtain a multimeter and have a poke around and check all your speaker leads on the ohm setting anything lower than 1.6 ohms and you have a short...also make sure that you have correctly loaded amplifier to..alot of begginer audio enthusiats overlook this important step and cook amplifiers!!

remeber impendance ratings, have a look on google, search "impendance formulas" and study up if your unsure!

hope this helps,ben

Still having amp problems

Hello lilmario,

After eliminating wiring problems and possible shorts, grounds and low impedance in the speakers, most likely the amp is failing internally. A partial failure of either the output MOSFET's or the thermistor. In either case, the repair requires removal and replacement of components on the circuit board. Depending of the age and original cost of the amp, such repairs are sometimes expensive.

I'd recommend having a professional audio shop test the amp and provide an estimate for repair.

Hope this helps.

Red protection light wont turn 2 green no matter what so the amp wont work

Hello mcis43fan,

The protection circuit can be activated by shorted or grounded wiring or it can be caused by a defect in the amp itself.

First, disconnect all wires except power, ground and the remote turn-on lead and see if the amp powers up normally. If it still goes into protection, the amp is defective, most likely shorted outputs and needs repair or replacement. If the amp powers up normally, test the other wiring for shorts and grounds. You can reconnect them one at a time to determine which one is causing the problem.

Hope this helps.

The amp goes right into protect when hooked up. how do i get it to work properly?

Does it have a antenna connector to turn it on. this sometimes is a blue wire that comes from the radio. This normally turns the amp on when the radio is turned on. you should have a power (red) ground (green or black) and a power control wire they are right next to each other on the amp

Power Protection Light Will Not Switch Back to Green

Disconnect all speakers, then turn the amp on. If there is no internal problem with the amp, it will go green. If it does go green, reconnect your speakers one at a time with the amp off then turn it on. when you connect the speaker that's causing the problem, the amp will go into protection. At this point, it's one of two things, a bad speaker wire (screw thru it or touching another terminal) or a bad speaker(burnt voice coil) to test that wire, disconnect the wire at the speaker and turn on the amp, if it's still green, all's well in the wire department. Meter the speaker with a multimeter on resistance, if it's blown the meter will read 1.... If you don't have a meter, connect the speaker that's having the problem to the other channel and test again, if it goes into protection, you've got your answer. Bad speaker. Hope this helps

Amp won't turn on

disconnect audio inputs and outputs and see if one of those are causing it , if it still does it with all audio inputs and outputs disconnected then there is a problem with the power amp

Red light

something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.

I have a dub 4001 amp

Take it step wise.

Unplug the inputs and outputs from the amp (be sure to mark the wires so you can hook them back up), leaving only the ground, +12, and remote wire hooked up. Now, turn it on. If the amp light goes red, the amp is broken. If it goes green, turn if off, plug in the speakers, then turn it on. if it's red, its a speaker problem, if green, do the same with the inputs, and you'll have your answer.

Power light

This could be a DC offset condition. Check you manual for what this means. Or other condition. First Disconnect the Subs and try it. If it still goes red then disconnect the RCA's and try it again. If the Led continues to go red after the click then the Amp is hosed. The Click you hear is an internal relay that cuts the subs in after a dely so you do not get the turn on THUMP of the radio at your subs.
