[QUOTE="i2ain2thunder, post: 8095299, member: 631331"] what is the max volume of your head unit? You sound like you've done your research and are going about things the best way you can, good for you! How I normally do my system is I set the HU volume to aprox. 75% (HUs may clip the signal if they are turned close to max volume) set amp gain to 0 set all bass settings to 0 disconnect speakers/subs from amp turn on, put in cd, hook up aux or however you are getting ur 50hz tone. go to the amp with the DMM, set to ac voltage. check output on the channel you want, then turn gain up on amp until you see the correct voltage u are looking for for your desired RMS or application. Now if your HU and amp are worth their weight you shouldn't need to get near max gain at all to get the voltage reading your looking for. Now doing all this will ensure you are sending the correct amount of power to your subs, however clipping can still be a factor even after you do this right. Some amps/HUs are just lousy and clip at higher volumes. Doing the above things will ensure the right amount of power, but how clean or dirty that power is has a lot to do with a lot of other factors. It sounds like you are running a lot of power, you will want to take time to make sure you have an electrical system that can handle that much power. things to think about: Wire, OFC is best, or silver tinned copper. CCA can be used but is not the most recommended, OFC is better for heat and efficiency. alternator, is yours stock? how many amps is it rated for, vs how many amps do you have the potential to be using, you may need a high output alternator. Big 3 electrical, upgrade alternator power wire and engine/chasis ground wires for engine to 1/0 or 0gauge. You may need multiple good batteries. The way to know what your electrical can handle is to get your amp setup, then play hard hitting music and watch your voltage. you don't want to dip much below 12 volts. [/QUOTE]
