I need a highs and mids amp and this is what i narrowed it down to for the $$ not going any higher than $100. I will pushing 4-6" subs and 4 tweets. If i can get at least 10 people to chime in which they would choose I will pick that amp and buy today. I am leaning more toward the RF because I had 2 punch 45 and a punch 60 back in the day and never had one single issue. BUTT! RE audio is "US AMPS" and you already know from back in the day there was no better.
