Help Dianose These PICS....

Another idea to test your amp ground is to leave the + lead of the DMM on the fuse block, and put the - DMM lead on the - terminal on the amp. If you are still gettin a funky reading, its most likely something with the ground.

yeah yeah, that's exactly what I did with both of them, so ground huh?

Well not nessicarly...... it could depend on the current draw for the amps and if its reciving enough for the amp to turn on... each of your amps dont require the same amount of power... to be powered. So if there is a short it may still be enough with the shitty ground to turn on a amp that doesnt require alot.
(Correct me if im wrong)

So you're saying if the speakers get short somewhere, then the amps would still turn on right?

If this matters, I had the DMM - on the - terminal of the amps and I could get a reading of 12V, when the DMM+ is set up like the first pic.

Thats odd.

Try putting the - DMM lead on another piece of metal and see if that changes anything.

Yeah did that too; im outta ideas, the only thing I could do is have the 4 gauge run right into the monoblock to see if something happens. Any more input guys??

The size of the wire should not make a difference.

Something else is eskew here. Right now, it's pointing towards the amps. It doesn't seem to be the ground because if you did what i said (+ DMM on the fuse block, with fuses out, and - DMM on the amp -) and it still reads messed up numbers it can only be two things.

1)messed up ground

2)messed up amp

fock! i hope its ground man, but doesn't seem right because I had the ground like that for at least 2 months, bolts still seems tight.

In the case of amp problems, how could it go wrong when it was playing fine for the last week or so? Install errors? All the gains were set right and I made sure none of the strands were touching the other terminals. Alpine's onboard fuse wasn't blown. ARGG!! so frustrating + no music in the car

Here's a test you can do.

Take out the amp.

Get 3 pieces of wire

Connect the amp + and the remote terminals with one piece, then run a wire from the amp + to the + battery terminal, then a piece of wire from the - amp terminal to the - battery terminal.

If the amp turns on correctly and no protect light comes on or anything, it may just be a wiring issue.

If you cant do that, maybe borrow a friends amp and install that in your car to see if it does the same thing.

Yo, check ur remote wire, also if ur HU has a on/off. Also bro, that happenned to mine and it was my fuse, it felt like it was working but it would work on an off every 2-3 min from vibrations knocking it in and out of connection.

okay, does it matter if i use 16 gauge, i mean there's no music playing or nothing.

at this point, both of my amps would not turn on, and i believe they are fried as of now. i get a stupid @ss reading even i run the 4 gauge straight into the mono block, where im positive the 4 gauge has 12v and ground is good as it gets, as soon as i plug the 4 gauge in, the reading is somwhere 1.1-.9 volts. remote wire i tested was 12volt with the headunit on, meaning headunit is fine. i just cant understand why both amps were somehow short and none of the fuses seem to blow. any comments?

i bet a million dollars that its the fuses in your distro block....I've had fuses screw up before but not completly blow, they'll look like they're not broken but they are.

x2 I have stated this to several people and that has been there problem. Just try some new ones its a cheap $3.00 and if it is not them you still have them for back up but sounds like you have tested everything that could be a problem. Maybe it is your distro block as well.
