okay, im gonna try to be very detailed here. i know this is another question on amp settings, but the main reason i have this question is because of my LOC. i will list the components to my set up and then ask my questions:

my set up consists of:

i have the stock head unit wired to this LOC (http://hempsteadelectronics.com/catalog/product_info.php?cPath=51&products_id=461&osCsid=5cc15a412d4a2b0c8eb18f0eedb3b4f5) from there it goes to a yzen ya-400 amp (http://www.yzen.com/y_series.htm) and that is wired to two kicker comps (http://www.caraudiodeals.com/kicker-comp-series-c128-150w-rms-ohm-car-subwoofer-p-950.html) in a sealed box. ive got this in a sedan, with my box facing the rear of my car.

i guess my main issue is figuring out how much voltage my LOC is putting out to know how to set my gain. and if anyone has any information on what would be the most efficient way to set my stuff up to get the most out of it, it'd be appreciated, im fairly new to this and would like to learn, any input is appreciated. here is a picture of the subs in the box

Are you still using the stock door speakers, running off the stock HU? Those subs are probably powerful enough to completely overpower the sound from them, so you shouldn't really need to set the gains at the perfect peak max setting. Just turn up the gain until your subs are loud enough to sound good along side your speakers, but not too loud, and not so loud that they distort at higher volume levels. You don't really have to do any sort of calculations or measurement, just use your ears and adjust until they sound good :)
