I got a really good deal on an AudioFrog 3 way (gb60,gb25,gb10) that I will be installing in the near future. I am currently using my iPhone to hec card in helix pro to Phoenix gold ti21600.5 to hybrid imagine 6x9 in front doors, and Morel CCWR254 in dash location (temporarily tweeterless) and 5th channel to a Dayton HO 12” sub. I could add an old school 2 channel Alpine amp for the tweeters but I am kind of wanting to try out different amp(s). I like the Phoenix gold amp but itching to try something else. What amp combo would you recommend that would be an upward and not lateral move for me ? Budget possibly $1,300 if I can get $300-$400 for my PG amp.
