Cadillac_Fresh Posted March 20, 2014 Report Share Posted March 20, 2014 Ok new to the forums here, Just thought Id start with some questions. In regards to this amp, I know the zues series isnt everyone's first choice but Im on a tight budget and its getting me back into the game after using my subs for a table for 2 years. Anyone know how to tune the "Sub Sonic" and "Low Pass" correctly. They're foreign to me. Realisticly its all foreign but I just play it by ear for now. The amp is a Hifonics ZFX1800.1d, I have two SVC 4ohm Power Reference Memphis 12"s (250/500 max) in pre-fab 42hz Memphis Box. It gets a solid thump but I noticed some of the higher frequencys (I think) are kinda just dulling out. Instead of a gorilla in a box it sounds like a bad stomach ache. Anything helps, Link to comment Share on other sites More sharing options...
soundstream15 Posted March 20, 2014 Report Share Posted March 20, 2014 Sub sonic should be set 5hz below your box tuning. So I would put it just a hair below half. Set your low pass filter to 80hz. Half way at 12:00 position will be fine Hope this helps Link to comment Share on other sites More sharing options...

Would be nice to meet some fellow car audio enthusiasts. In regards to the DD1 Im gonna be picking one up as part of the arsinal on top of the crossover meter. Tried to contact steve about maybe a discount code but no reply. What exactly is the gain on my amp? Being as there is no official gain label. Is that the "Bass EQ" Part?

Did what you said and Im noticing a pretty significant difference. I also turned the bass EQ on the amp completely off. Not really any more muffled tones.
