A while back when I had my Viper d1200.1 for the short time I had the amp I loved it but I hated those ground, power, and speaker terminals. In two months I'll be getting another amp for a new system. Does the Directed 1100d have better connectos than the Viper? Also does the Directed have a subsonic filter and phase adjustment? I just don't want to deal with the Viper's connectors again so I'm looking at either the Directed 1100d, Hifonics TX1505D, or PA 2400DB to run at 1 ohm.
