I have been searching for weeks for the perfect amp and have finally decided between these 2. The amp will be powering 2 - 15" Soundsplinter RL-p's vented around 2.5 to 3.0 cu ft. each @ 28hz. Subs are 2ohm DVC so I need power at 2 ohms. The subs are "conservatively" rated at 500 watts rms a piece however, the drivers use the exact same motor as the eD A's and the SI D2's I'm told so I'm not worried about putting serious power on them. I am trying to decide on whether to go with a new 1501 or a refurbed 2500.1. The price is the exact same. I have heard good things about both amps and I'm guessing i would be putting almost the same amount of strain on my electrical system since I would be pushing the 1501 pretty hard or the 2500.1 with the gains nearly all the way down. So to get to the point, what should I go with. Research and opinions on either amp makes it hard to decide for me. And my EQX has a SS filter so that's not an issue either. Thanks for any opinions.
