Sounds like you have loose connection, bad connection, loose fuse, etc... Pics?

what distro?

i have a optima yellow top up front....ran to 2 kinetik 2400's in the back....which are ran to a PG distro block for both pos n ground.....at the rear batts i get ~12.5 with car off.....then at the distro it drops to 10.9 and it is this same reading at the amps

i'd take pics but i have no digi camera....im going to mull over the connections again to see if i notice anything that looks loose

what is between the battery and the distro? wire? is it loose or corroded?

this is where the problem is //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Check the voltage at the batter, one post to the other,

your voltage and the power and ground terminal on the amp should be the same.

no higher, no lower.

i.e my amp is 12.5, my battery is 12.5 voltss...

this probably means you have a bad ground, a way to check that is to run a lead from the ground post on your battery and put your neg lead from your dmm on it, and put the pos lead on the pos terminal on the amp, if it reads 12.5 or whatever your battery is, then you kjnow youave a ground problem.

Edit: I can't type fast enough....

so i did what u said and i got the reading for my batt (12.5).....then i did the reverse of that....put pos lead at batt and neg lead at amp and i got the reading for my batt (12.5)....what does this mean?

It means your ground is solid. Since its grounded directly to the battery that shouldnt have been a problem anyways. Check your connections. Like stated you have a loose or corroded connection, most likely at the d-block.

so, pos at amp with neg at battery is 12.5

and neg at amp, pos at battery is 12.5 also?

if i put the leads on the d-block itself i get the low 10.9 reading....does this mean that the connection from the batt to the d-block is the likely culprit?
