akuma4u Posted November 5, 2015 Report Share Posted November 5, 2015 Hey i got a hifonics x1500 amp i need to get it to 4volts to match my pioneer head unit the amps sensitivity ranges from 9v to 0.2v where is 4 volts going to be? some days i have it around 12 oclock , some days i push it to 1 or past 1, and sometimes i have it at 10 or 11.. i cant figure out where 4 v is and i dont have a voltmeter or anything to test.. so anyone with a hifonics amp pls let me know.. thanks also on my pioneer double din avh x4600bt, the sub level goes from -24 to +6 is it ok to leave it at +6? or should it be set to 0? i find when its at 0 the gain has to be turned up quite a bit or a lot of bass boost has to be introduced in order for the subs to thump proper..

crispy_chick3n Posted November 5, 2015 Report Share Posted November 5, 2015 thank you for your contribution not a problem. hopefully everyone will play nice and you can get some help, but id start off first by going out and getting some kind of multimeter. if you are installing anything electronics wise and you don't have a meter... you're doing it wrong.

meade916 Posted November 5, 2015 Report Share Posted November 5, 2015 don't worry about where 4 volts is at. If you don't use an O-scope or an SMD DD-1 to set your gains, you may as well just guess and do whatever sounds best. Basically no matter what you do, it will be wrong if you don't do it right All SMD products + MORE available at my store here! https://wccaraudio.com/ Subscribe to My Youtube Channel!

meade916 Posted November 5, 2015 Report Share Posted November 5, 2015 FYI: your amp doesn't put out 4 volts when the "gain is at 12 oclock" the source is what "puts out volts". The amp accepts those volts. Whether or not you have enough "volts" coming in from your source will determine how high the gain needs to be set. If you have very low clean output voltage coming from the head unit (and anything in between), you will have to turn the gain up higher on the amp for it to reach full power. Gains are on the amp to make up for low input voltage. Ideally, if you have a ton of output from the source you shouldn't need ANY gain or very little at all. The gain is not a volume knob. It is a matching knob. All SMD products + MORE available at my store here! https://wccaraudio.com/ Subscribe to My Youtube Channel! Over 1,000,000 subscribers strong!

It is a matching knob. yes i understand that the gain is not a volume knob and its a matching knob instead hence why i asked where 4 volts would be roughly due to the fact that my HU is 4 volt pre out (pioneer avh x4600bt) and i want to match the pre volt with the sensitivity knob. Believe it or not, i have called many car audio shops in my area to scope and set gains professionally (i dont have the tools to do so) and either they all say 1) oh we do it by ear or 2) they dont have the DD1 or tools to do that either or 3) they charge a ridiculous amount Link to comment Share on other sites More sharing options...
