I'm stupid when it comes to car amps so a little help please. I have a rf power bd 500.1. for years i've been calling it a punch 500s and was about to sell it on ebay when i noticed it's not a punch at all. i had it hooked up and loved but don't know if the punch is a better amp or is the bd 500.1 better. whats the diff and was the msrp vastly diff? thanks for any info guys.
