ok i am going to have a bunch of speakers on a t15004 amp. say i want to only play some of them, since they're on the same amp, is there anyway that switches can interupt the speakers from getting power? relays or anything?

Study this page, especially near the bottom https://www.the12volt.com/relays/page5.asp------------- Prepare your future. It wasn't the lack of stones that killed the stone age.

that confused the s*** out of me. lol. ill study it some more, so its possible? i figured that i can just have a basic on/off switch inline on each speakers positive lead, but then how to turn them all on or off at once?

Use a standard Bosch type relay.
You can put one of the two speaker leads through the relay connected to pins 30 and 87a. Then, pin 86 to positive 12V. Pin 85 gets a ground via a switch.
In this way turning the switch ON will CUT that speaker.
Whatever speakers you want cut at once, connect the pin 85 of that particular relay to the switch.
You can have more than one relay on the switch.
Watch out for impedance.

Impedance might not be an issue but, because I don't have details about what you plan to do, I thought I'd alert you in case.
For example, you can't put four speakers in parallel neither can you short the outputs for obvious reasons.

Never mind what I said - just observe impedance as per the amps manufacturers suggestion.
