show us your remote winch solenoid location

Yep. So yea that's the load drop when battery is under load.
Voltage drop is the difference between source and motor from the cable.

Technically, yes but battery voltage that drops when under a load, such as cranking the engine, is still very commonly referred to as 'voltage drop'.
I have a drop in measured battery voltage of 2v when using my winch.

I think that would be very common across the board, but very open to the style and quality of your battery and alternator..

Speaking of voltage drop when starting, is there a way to stop the headunit from restarting when i crank the motor without hooking to the aux battery?

Is it wired direct to battery or via something else.

All batteries have an "internal" resistance. The value of this resistance depends on the level of charge and the health of the battery, but is usually very small (fractions of an ohm). This internal resistance can be thought of as a series resistance when thinking about a vehicle wiring diagram. Like any resistance, the voltage dropped over it is proportional to the current passing through it (V=IxR), and the more current that is drawn from the battery the more voltage will be dropped over the series internal resistance. With this in mind, the thickness of your battery cable will not change the internal resistance of the battery. Sure, you need to have a decent sized battery to winch cable in order to minimise the voltage drop over the cable, but when you start to operate the winch and draw lots of current you will always get a voltage drop due to the internal resistance of the battery.

Its currently hooked up to the standard headunit wiring. Its a dvd headunit so maybe it needs more power to run.

What year? I know my gq is wired directly to battery and the signal wire is to the accessories. So only come on when key is on.
But my 02 falconer turns the ac and radio off when cranking.
