I wanted to make portable speakers, that are decently loud. But how long will the power last with this battery, since I can't post links I can only post what I can get.


Speakers I have: memphis pr63s speakers

Battery: 26 AH SEALED 12 VOLT DEEP - CYCLE RECHARGEABLE BATTERY

Head Unit: Pioneer DEH-1300MP head unit

I have an old head unit, but not sure if I can use it with speakers. It would save me $50.00

Clarion
Model #: PN-9403C

Let me know if I am missing anything, and if I need a different power source.
