hump day bump

 

you didn't disconnect the speaker wire from the amp did you? you probably shorted the speaker wires together and damages the amp's outputs.

 

that's more along the lines I was thinking, Paul. once connected, ground connections are usually pretty good.

I taped one of the speaker output wires so I don't think thats it. How should I test the outputs with a multimeter?


Thanks for the replies

 

it still could be, if that other un-taped speaker lead ended up touching a ground.

if you suspect a grounding problem, then check/fix it.
other than that, there is little you can do with just a meter to test it.

 

you're right, I'm just afraid that I killed my amp and am somehow trying to talk myself out of the possibility of needing a new one. I'll run a new ground and see what happens. Thanks for the help thus far.

 

if you want to see if it's the amp turn the system on and see how much, if any, VAC you're getting a the amp's output terminals.

 

I hate searching and finding unresolved threads so I figured I'd let you guys know that the solution to my issue was indeed a bad ground. Apparently it is possible to have enough power to turn the amp on but not hit the subs hard.

 

good for you. glad to hear you got it fixed. how did you discover it was a bad ground?

 

I took the ground off, created new crush ring terminals that were super tight using a hammer ( I have 4 guage cable), and changed the ground point from the fuel pump cover screw to the allen bolts which fasten the 60/40 seats to the same pivoting bracket in the middle of the back seat. Its the only part I changed or replaced so by process of elimination, it had to be it. I did also take my amp apart to see if anything looked charred or busted, ran continuity tests from the ground/power connections to both the outputs and the circuit was good so I assumed that the amp at least could make a circuit. FWIW I have a Pioneer GM-5000T bridged to a single 10" MTX Thunder 8000.

 

where exactly did you connect your ground to?

im looking for the easiest most convenient place to put it without having to drill or anything like that with no problems.

thanks

 

If you fold the seats down and look at the bracket that holds the backs of the seats together, you'll see 2 black allen bolts on the back of the bracket facing the back of the trunk. You can connect to these without the seats kinking or bending the ground connection if you repeatedly have to pull you seats up and down for cargo.
