power problems

Did you hook up a battery isolator? if not you need to. Stinger makes a nice one that is not to expensive. What the isolator will do is let on battery run the car and the other one run the system but the alternator will charge both.DO it right, Don't use SONY

DO NOT INSTALL AN ISOLATOR! Read this recent thread regarding the subject. There are also many others regarding the very same subject on this board, but this is the most recent.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

ok i will read it, but I think everyone mught think I have one battery for my truck and another one for my AMp but My truck runs off of 2 batteries. It is a diesel with 2 batteries

I was going to guess this small fact but did not have a chance to. Any luck with that resistance reading yet?Top Secret, I can tell you but then my wife will kill me.

no im in a air force class all day just comming home for lunch, does anyone no wher i can download a test tone so i can set my gains

I down loaded a test tone (I think) put my desk at about 3/4 with bass and trebel at 0, disconnected the sub, and conected my multimeter on  the = and - for the sub output of the amp and  I could turn up the amp all the way and did not get any volt reading from it. I looked at the jl audio tutorials and I should have gotten at least 47.3. Am I doing something wrong

Set your DMM for AC volts.  And we will need to know about that ground resistance, too.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
