Why Does My Sound Go Down After Certain Volume?

Question:
I have an Alpine head unit, PPI 1000w rms amp, 3 12"subs. I turned all the settings on the amp on the highest level (which i think is wrong, but i figured i can just adjust everything from my head unit).When i turn the volume to 22, it sounds like its bumping hard but once i turn the knob to 23 the bass definitely drops and when i turn the knob higher to 32, the bass is bumping harder than it was on 22 but the treble seems slightly distorted but not too distorted. As far as I can remember, it didnt do this until recently. Im pretty good in adjusting the sound to how i want it to be and this is not really a huge problem for me but it does bother me still. Any specific settings that i need to adjust would be much help. Thanks.

My fm car radio has stopped receiving fm what do i do?

ur not suppose to put everything on full u have to go to a speaker place so they can tune it all the frequencys gain and everything what u are doing there is distorting all ur subs. and if u go to get it tuned and it doesnt solve the problem then u need a equalizer to help out ur system. i have a friend who busted his whole system doing what ur doing.

I'm guessing that either your amp or head unit are going into "protect mode"

What kind of enclosure should i get 10" subs?

Turn down the levels on your head unit. If you feel like you need more bass, turn down mid and treble and use the volume knob to compensate. Turning up the levels will ALWAYS cause clipping/distortion and if your amp sees distortion it will go into protection mode to stop the stereo from blowing your speakers.

Anyone know where the 12v supply is?

Make sure your gains are set correctly too.

play around with the setting on the amp try turning them down to half then set the head unit up, try that if you are still having probblems it could be the head unit playing up

You need to set the gains correctly or face buying new equipment.
