Question about Kicker 06ZX750.1 Car Audio Amplifier
there are 2 reasons for it to be going into protect mode 1 is heat 2 is the load on it. if it is going into protect mode soon after it starts there is a problem with the speaker. if it is after it has been on for a while it is that the amp itself is overheating. hope this answers your question

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
