Thank you , the top speaker is from my Line 6 amp (75 watt) the other speaker is from another amp ( 30 watt ) but an 80 watt speaker ... Don't know nothing about impedance just thought the 2 speakers would work together , stupid eh ?
My Spider iv 75 has just lost all power , I built a whole new casing to hold the brain and speaker was working ok but seemed to lose all power nothing lights up
