Maroon97SL Posted July 19, 2010 Author Report Share Posted July 19, 2010 http://www.stevemeadedesigns.com/board/topic/4382-setting-amplifier-gain-control/ So i hook up a volt meter to my speaker terminals on my amp? Man that crap is confusing lol, i read it but my mind isn't processing it right. What i get from that is i have to put in a test tone of 50hz. Have bass boost all the way down, hook up a volt meter to my speaker terminals, have the H/U volume to 75% and then turn up the gain till my subs start clipping/distorting/sounding muddy, is that correct?

Budget Build, I spent about 330$ for the setup. but its a crx, if you cant fart and do a 150 in a crx there is something wrong... Link to comment Share on other sites More sharing options...

Have bass boost all the way down, hook up a volt meter to my speaker terminals, have the H/U volume to 75% and then turn up the gain till my subs start clipping/distorting/sounding muddy, is that correct? Step 1: You need to find the wattage to voltage conversion for your amp and subs (sub/amp power ratings). That will give you the set point on the amp. Once you have that: Turn the gain and bass boot all the way down on the amp. Flatten out all settings on the head unit (bass/treble/eq's/boost/etc). Disconnect your subs from the amp. (*Don't forget your mids/highs and disconnect them if you want to make sure they don't blow.) Turn the head unit up to it's max volume to find out what it is on your head unit, and as a general rule, 75% of that volume should be free from clipping. Set the volume to that 75% volume, and set the 50hz track to repeat. Connect your DMM leads into the speaker terminals on the amp, and slowly turn the gain up until the voltage reaches your number from step 1. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Then don't turn it up louder than your 75%, or crank the boost, or the settings on the head unit...and you'll fairly close to as loud as you'll get with that setup, and still keep your stuff safe. An Oscope is the best method for all of this, but most of us don't have access to one...and I can't justify the cost. Quote Link to comment Share on other sites More sharing options...
Deschain420 Posted July 19, 2010 Report Share Posted July 19, 2010 I am pretty tired, so I'm not sure if my last post is totally understandable. Anyway...from a quick look, it seems like your converted number should be 31.62 volts for 500 watts @ 2 ohm. Quote Link to comment Share on other sites More sharing options...
skittlesRgood Posted July 19, 2010 Report Share Posted July 19, 2010 lol late night advice always gets a little fuzzy. if you still need help, JL has a tutorial that is pretty easy to follow. it has pics and step by step instructions.

If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.
