Posted March 24, 200718 yr i just put in my sundown 1500D and it turns on, but nothing comes out of it volts or anything
March 24, 200718 yr Do you have the meter set to volts AC?Sub preouts aren't turned off on the head unit?Crossovers are set correctly?
March 24, 200718 yr Author No, its on DC voltsnope checked those too they were onand i dont have any xovers on my HU, and i havnt even played with them on my amp, what do i need to have those set to?
March 24, 200718 yr No, its on DC voltsWhat comes out of your amplifier is not DC what do i need to have those set to?I'd set the low pass filter to somewhere around 70-100Hz, the exact frequency will vary based on your install and listening tastes, but I try to fiddle with it until I can't hear where the sub is coming from.
March 24, 200718 yr Author oh ok lolmy LPF is set to 35 right now lol, ill play with it somesubsonic.. what should that be set toand also my phase? Edited March 24, 200718 yr by alex
March 24, 200718 yr oh ok lolmy LPF is set to 35 right now lol, ill play with it somesubsonic.. what should that be set toand also my phase?That's another reason why you aren't getting much output Subsonic...if you have a ported box, generally 5Hz below tuning is a good place. If your enclosure is tuned below 35Hz or so, you probably won't need it turned on at all. If you have a sealed enclosure, you definitely don't need it on.Phase is one of those things that you can fiddle with, there's no absolute right answer. Try it for a while one way, reverse it and see if it sounds better/worse.
