Default Aftermarket AMp question?

DO you guys on the forum with aftermarket stereos typically see amp wires (multiple amps) grounded to the battery terminal??
is there other good options for grounding large amps??


I just bought this used bike,
more info:
Has (3) mono block amps,
older high output stator,
New battery (week old) i just added,
looks like Newer regulator by cycles

That's one way to do it i guess. i plan to run the ground wires to a distribution block, and from there run one wire to the Battery, and then one from the battery to the frame, properly sized of course. you need to look up the wire requirements for your amps and go from there and see if the ground wire coming off the battery going to the frame is sufficient. maybe others with more experience will chime in.

ok guys figured this out - you will not believe this:
bought a starter back up button and that is what was causing all my short problems. . .
Has there been any problems with these push buttons shorting to ground..???
ever since i put on: push caused the blows out the 15 fuse for all my lights, speedometer, odometer and turn signals.

recommend just keeping long wire in your pack to jump if you need too NOT adding the button.

Best place to ground one or multiple amps on the Harley, is the frame ground post, just FORWARD of the bettery ,, on the right hand side of the bike as you are sitting on it ,,,,,,

the ground source for the entire electrical system is at this part of the frame NOT the battery ,,, and distribution blocks sometimes make the situation worse, not better, depending upon how much current the amp is drawing ,,,

that is also why the negative post of the battery is connected to this same frame grounding post ,,,,,
