Buddy of mine had a mtx ta91002 laying around. Went to just test to see if it would power up. Just use some short wire power ground..jumped power to remote and to a battery..the amp lit up..made a woosh sound and started to smell a little burnt. I immediately disconnected. No i didn't reverse the power and ground. Don't think the amp would have lit up if i had. It would have just fried. Anyone have any idea what this could have been
