Hey whats up people? Let me gues your both running RCA lines to your powered tubes? with auto turn on? I dont think its a heat issue at all. I think its the auto turn on issue. Im up hear in michigan hot hot hot weather last couple of days. look hear
I dont know if this helps but dont bash the Bazooka name before you call and talk to the right people. I have hade PYLE and Kenwood sub systems The Kenwood took up the whole trunk of my NEON back in 94. well I get better sound and mirror vibration out of one 10" bazooka
In the back of a Jeep Wrangler with a soft top. Nothing to resonate off of. So Please talk to the right people before you start telling people to buy other products. Oh and bye the way they do sell a cooling system for the amp On your tube.
its called a C.H.I.L. unit. Lookes pretty cool but try the remote turn on first before you start spending any extra money.
Good luck to you.
