when wiring speakers what is ground on the amp

[Krains]

my amp doesn't give an indication of what is positive and what is negative when connecting the speaker
The bottom are the ground but no indication if it plus or minus
How can I tell?
The amp manual does not say

If the connectors are red and black, red is + black is -. If you're referring to car audio stuff, I have no idea what is standard these days.

I believe it would be helpful to know the make.. model.. and classification of the amplifier to better assist you.

On the bACK OF THE amp is has left and right speakers...The bottom says ground but there is no other identifying information such as colors or plus/minus

Generally speaking: Music is AC so it really doesn't matter, especially if it's not marked, as long as you connect both speakers the same so they are in phase.

A pic would be even better.

Ground is typically connected to the - terminal on the speakers.

Those things marked 300W are convenience outlets. Don't insert anything in them except AC plugs for devices rated at or below the listed rating.

We have no idea what color your speaker wires are...

Black wire (or whichever wire connects to - on the speakers) connects to the terminals marked "GND", and red wires (or whichever wire connects to + on the speakers) connects to the top terminals. No need to apologize for asking about this stuff; it's how you learn.

While you're back there to connect the wires up, take a sharpie and mark the terminals "+ and -" accordingly. Or use a label maker if you have that.
