[QUOTE="eXistence, post: 8133041, member: 650157"] Ok I have a pioneer gm d 9601 mono amp and a alpine type R 10 500 watt RMS Dual coil 4 ohm wired into a 2 ohm. I used two apps on my phone to find the voltage I need to set my gain from the amp. I used this one app called Audio Tool Kit Pro. In there it asks on "amp gain settings" what the amp rating is "RMS". I put "800". Then it asks for Amp load which I put "2" since I am running it in 2ohms. I then hit calculate and it gives me my number "40 volts AC". I then use another app called True Tone that gives me my tones to play through my speakers in order to set my gain. I go ahead and hook up my DMM to my amp. Put a tone of 50hz on and play. I turn the gain up until I hit 40 volts. Which wasn't very much to move. Btw my headunit goes to 35 volume and I left it at 26 which is right at 75%. Its Kenwood DDX 719. Now my question. Is this to much power for the amp and or sub? I don't want to fry the amp or anything or blow my sub. Another thing is I put the DMM into ohms and tested my sub and it was reading 2.5 ohms. A while back it use to read 1.8 ohms. The sub is pretty old as well. [/QUOTE]
