Real question

Silver Member Username: RvlacosDD 3512 United States Post Number: 291 Registered: Sep-06 | alright i been trying to set my amp gain correctly and sub tools website says i should be at 31.6 volts at the speaker outputs. i have unlimited access to scopes, dmm's, signal generators, pretty much any tester for electrical components. and i still cant seem to get it i did everything the site says to do but adjusting the gain doesnt change the voltage. is it suppose to be ac or dc voltage? i tried both. also when i did an ohms check it looks like my amp is seein 2 ohms instead of 1. im confused as hell ill check the wiring 2morrow to make sure a speaker wire didnt come off, but settin the gain is reall bein a pain in the ash. please help i could get the local shop to help but i wont ever learn to do it myself if i always get them to do erything, thanx |

Silver Member Username: RvlacosDD 3512 United States Post Number: 304 Registered: Sep-06 | i had everything turned all the way down the rms is 1000 at 12.5v and 1330 at 14.4 and at idle i usually run 13.8 or so only once dropping to 12.8v. my sub is a dual 2 supposedly wired to one ohm but i am reading a 2.2 ohm load so ill take it out and test it and make sure a speaker wire isnt loose or fell off. but regardless i cant understand y turning the gain up doesnt change the voltage.... diyers rule, lol its making me go crazy- |
