tuning voltage

Hey im back lol, I havent been on in like years, anyway im wondering if anyone knows the tuning voltage for an MTX 4001 at 2 ohms? or is JL the only company that uses tuning voltages for their amps?

Setting gain by voltage output is very vehicle-specific.  Perhaps the maufacturer gives power data with car's voltage of 14.4 as default...and your car is measuring 13 V while playing the system.  You would have to figure out the reduction in power and go from there.

You will also have to have complete acceptance that the power output of the amplifier as specified by the manufacturer is true.  What I'm trying to say is, it's easy to be off the mark if you set gain to a specific voltage derived from manufacturer's data and Ohm's Law calculations.

My advice is to set the gain by standards:  by ear, to hear the clipping.  Then (if you wish), by calculating the voltage output and measuring it, as a way of double-checking your hearing.

okay thx for that info, ill just tune it by ear for now until I get a better system.

I like to use sine wave test tones because you can hear the clipping immediately.  Do that no matter how high the quality of the gear, and use the voltage measurement as a check.  You're on the right path, though.  You'll get it tuned in right.
