20 Most Recent Kicker (ZX750.1) Car Audio Amplifier Questions & Answers

Also check your fuses. there may be a fuse for the in-tank fuse.

Are you getting any sound output at all from amplifier?
Is there a popping or banging coming from speaker?
It could possibly be a faulty output mosfet that is ocillating cause DC to leak onto the speaker output causing it to flip into protect.
please advise
thanks,ben

The output input cables try that first

U have a short or a connection problems

It maybe the specker or the input output cables bad

It maybe the remote wire doesn't have power

Turn the high out put a couple clicks back

It maybe the input out put cables or called rca cables

Maybe it got to hot

Your amp went to safety mode to keep from blowing your amplifier

Maybe rca cables bad

The specker maybe bad I have same the problem

My specker was working fine then the am went to on protection mode and backs power mode but my specker doesnt work but on when my volume is low

Maybe u have a short circuit somewhere

What size specker do u have

Thankyou for the detailed fault description..it 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 ohms..buy 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

The stereo on the remote lead, make sure its not the power lead, the remote is what clicks your amp on when you start your car. So it goes from stereo to amp
