Bra, you are clipping the HELL out of you amp.

"at max volume" is your problem.

fixed

max volume i play the system past 35 the issue occurs 35 of 50 i dont go to max volume

i can drop the volume and up the gain or bass and it comes right back (0 bass boost on amp

quick fix - turn gain and bass boost on the amp ALL the way down, set low pass at 80hz, turn sub control on head unit 75% of max

Turn CD player at 75% max volume (this should be the highest you turn it up)

Slowly bring the gain up until you are happy with the output, do not go more than 75% of max gain - If it clips turn it down and leave it

I would not turn the amps bass boost up unless you really have to, but same thing if it clips turn it down

Even with turning the volume down, upping the gain or bass will still cause your clipping.

You need to set your gain according to your input voltage or you will end up smoking something.

The above steps will help get you very close to where you need to be.

It sounds like you are pushing the amp WAY to hard.

low passs is at 75-80hz set with test tone

amp gain set with dmm

deck volume at 35-37 of 50= 75% it dose it at at 33 and the songs not even loud

when i play bass tracks or other songs i have it at 36 and up the basss to 2-3 and no issues

Again, your amp is clipping. You may have already damaged your amp.

You say that you set your amp with a meter. How did you go about this?

maybe you have the wrong polarity? you could TRY switching the pos/neg on one sub and see what happens

I LOL'D HARD (not at you op) HA HA HA

50 hz tone with boost up? bass up? settings? was the tone at 0db, 5db, 10db. All of this makes a big difference.

The "electric shock" you are referring to sounds like the amp running out of power(power supply)

And what happened with the first amp?

Hey OP, can you take and post some pics of your ele connections, settings and what not?

It may help us to give you a better answer.

Whats the voltage at the amp dropping to?
