I'm new here but I am interested in getting 2 down 4 sound jp34ab class ab amps or a sundown audio salt 2000.6. I am running Hertz MLK1650.3 legends in the front doors and Hertz ML1800.3 8 inch with Hertz ML280.3 tweeters. I'm getting the Hertz MLCX2 TW.3 crossovers. I want to know which would be the better quality amp and give me the best sound quality.
