I was hoping you all could help me with this problem I've been having. I feel that my subs are not hitting at their fullest potential. I have a pair of Fi SSD12s (H-QTS) in to separate sealed boxes I made (sealed with a cubic volume of 1.25 cuft [sub displacement included]), to power it I have a Hifonics Zeus ZRX2000.1d, 2 ohm load at subs; running it with Raptor 4 ga, and a Raptor 150A fuse (triple checked all connections). I was told by the people on this for and elsewhere that the ZRX2000 would be just fine on the subs, and I also thought that Hifonics was CEA-2006 compliant. I just don't feel the huge improvement I was expecting by upgrading the piece Audiobahn 10's I had, but they really aren't which tells me I must be messing something up.
Should I run the subs at 1 ohm, do you think the amp could keep up? I was gonna get a hold of Hifonics and see if I could return it and get the ZRX3000 instead, get some more power with little money. Or maybe going with their Brutus line? Bigger enclosures? Any thoughts?
This is all in a '89 SedanDeville by the way.
