seems like the punch 12 wasn't loud enough. If you gave her adequate equipment, she wouldn't blow it!I am still waiting for my GP audio orange heat shrink to get here so I can finish my cables. In the mean time I sold my BNIB D4S JP13 to my sister. She is going to be running it on a pair of 10's that I am sure she will blow quickly like she did my RF Punch 12 some time back.
