why does my amp shut down when i put the volume high?
i have a 240 watt amp powering a 300 watt sub and when i try to put the volume up it shuts off i have everything connected i switched the ground wire 4 times and it still wont work i have it connected to the battery but only to a terminal should i hook it up right to the battery i don't know what to do please help!!!!!!!!!!
and it does not get hot its cold as can be when i touch it.
its not the fuse or the power to the speakers beacuse i tried lower wattage speakers and those did the same thing
as u can see here is a pic and the battery is under the fuse box i am conmnected to the positive extension cable there

You should never turn up an amp more the half way with the gain or boost this will kill your amp you are now putting more power into your amp then you need to, Your amp life will be minimum, This is why they make more powerful amps!
Remember it is a amp! most amps are set to be used at half gain in this way the amp will get louder at a normal regression as you turn up your music
And also they will tell you that 2ohms is good yes it does double your power but it will inturn give you loss of amp life!
No matter what 4ohms sytem will work a life time of your car if you need more power you always buy a more powerful amp
You need a more powerful amp!
Its going to blow!

Most common reasons..
1. Your impedence is too low. When you turn up the volume the amp detects too high a current flow and protects.
2. Faulty wiring gets shaken loose causing shorts.
3. Gains set too high, and/or bassboost too high causing over current protect mode.
It can very easily be a fuse issue. The fuse is soldered to the ends. The soldering can melt/come loose and then no more power, but the fuse looks OK.

If I understand this right you don't have enough power going to the sub.
240 - 300= -60
does not get the last 6th of volume.

connect it directly to the battery
it does no good if its just drawing from the battery and not connected directly to the alternator
