doood take your subs off the amp and set all filters flat. play a 60hz tone get it to 38.6v then plug it in and tune it....

unplug ur subs and set it to 38.7 ac volts with a 50 hz tone, keep ur subwoofer level all the way up. if u want to set it properly with the most output get a oscope or a dd1.

I told the man it was too high on the first or second page. If the output is not enough then you either need to get a second amp and strap them, get a bigger amp, or get another sub and amp combo. You are going to end up wrecking your amp or sub or both. If you don't want to listen that's fine, but quit asking if its okay because we have told you it's not.

If you are waiting for someone to tell you it's okay so you feel better about doing it then fine, it's alright. It might sound even better if you turned the gain up to 7 or 8.

Also, the gain is not a volume control.

any newz?

sorry worked all day, well i used a -3db 50hz tone, volume 39/50.

unplugged my subs and set the freq to 65(ish) if u notice on the amp it goes from 65-like 120 or something i forget lol so its hard to set it to like at 80ish

and the gains at like 4. its reading 38.8

your amp is efficient //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Your not pulling 1600w. To pull that the amp would need to be 100% efficient.

There is a mistake here

He has the LPF crossover set on his headunit to 85 hz

AND he has the LPF crossover set at 65 hz on the amp.

That is wrong!

turn the crossover as high as it will go on the AMP

I use an 80 hx LPF on my headunit and have the LPF on my amp set to 250 hz or whatever as high as it goes.
