Sounds like the remote power is not wired properly to shut off when the car does

I have a kenwood kac-9152d amplifer and it works just fine for about 10 minutes then just shuts off and subs dont work, about 30 seconds later my amp turns back on with the subs.

make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.

Well i was driving one day and my subs just whent out so i bought brand new wires and hooked everything up but the power protector light turns red whenever uu turn it up past volume 10 i really do not know...

It sounds like your amp is going into protection. I know it's frustrating, but this is actually a good thing. If you subs you have are drawing too much power and the amp can't keep up, it will shut off instead of melting the board. Usually, the protection mode only last a few seconds. The user normally turns the music down that the protection shuts off and the music plays again. I recommend looking at a larger amp for your subs, if you are going to play them that hard.

What would cause my fossgate t1500 to shut off everytime the bass hits hard I have two t12s that it pushes

Sounds like your amp isnt powerful enough to power your subs, whats the wattage of your amp and both subs? Its shutting off when hard bass hits to protect itself from blowing, a good feature as a blown amp means a new one. an amp should always be more powerful than the speakers / subs you are connecting to it. for 2 500w subs your looking at a 1200w amp minimum.

Why my amp shuts off when the volume is turn up and comes back on when lower the volume? I have 2 15 Q Power subs and Lanzar MXA3000D Amp

I used to own a Lanzar amp. I dont know if ours will be the same, but mine had a special safety feature. If i turned it up too loud it would go into it's safety mode and shut itsself down to protect the subs. You can bypass this security setting, but it is not recommended, as it protects your subs from a great deal of power.

KAC9103d been running great for a year, factory refurb. for a month been losing sub output. checked all connections again, everything good. Turned on went driving 15 minutes later lost bass ckd again red...

Could be that you have a partially roasted(blown) coil on one of your subs which will function- but will keep tripping your amp.You can check that out just by using a different set of subs to listen to and by the process of elimination if the problem goes away then you know where the problem is at.Also check your gains you might be riding the gain a little high which causes distortion which causes heat(FAST) which will cause the amp to shut down completely or some amps will decrease output in a programmed attempt to save itself.turn the bass boost down to half if you even use it at all- that too can cause massive distortion in the amp itself,meaning only that if you have the bass boost on your deck turned up and then you turn the boost up on your amp the sound signal is then WAYYY distorted which will cause a thermal shutdown too. Last thing is to make sure that your subs arent running below 2 ohms because i believe that particular amp is designed to put out about 900 watts at 2 ohms.good luck

Cut out

rewire the subs-each sub you want in series=8 ohms per sub-then at the amp wire the two 8 ohm subs in parallel which brings the ohms back down to 4 ohms which is optimal for the amp and it shouldnt shut down on you any more-try that-good luck

Alpine MRD-M500 Amplifier

That is a code to inform you of an issue, and to help direct you to a particular area of concern

HOT & E-1 = both for heat issue

E-2 = for a voltage issue

E-3 = for a current issue.

While yours is a current issue, that reflects a problem with your input or output signal pairs. You should disconnect the subs at the amp, then operate the unit as normal to see if the code reappears. This is the start of your process of elimination, where as you will be able to determine the general location of the issue, weather it is before - internal - after the amp, hence If after the subs were disconnected, the code did not return then it would be obvious that you should focus on the subs and their signal pairs. troubleshooting in small increments until the issue is discovered.

Hope this helps...Good luck
