I tell him the advice you guys tell me, just to see what his response will be, to kind of get a knowing of his knowledge.
He said everything I have now is fine, I should only take your guys advice if Im trying to build competing subs.
you take the leads from the dmm and stick the positive in the pos speaker output and the neg in neg speaker output. set the ddm for volts ac. then you figure out how many volts you want by this formula: square root of (rms x impedence). so for example your subs are wired are 4ohms and you need 600 rms, you take 600x4= 2400 then you find the square root of 2400. and that number is the volts ac you want you dmm to read when you turn up the gain. you will want to have you head unit set to about 3/4 volume. and you will need a 50hz test tone. and yes turn you gain to zero till you set it properly. oh and btw your friend is a retard.
Ok, you are going to unhook the subs from the amp, and zero out the gain.
Once you have finished that, you are going to play a 50Hz test tone through the HU @ ~80% of max volume, everything but the subs should be hooked up to the amp.
Plug the DMM into the amp, just like you would with the subs, and set it to measure AC Voltage.
Using this equation sqrt(Watts x Resistance) you will get ~24.4 sqrt of (300 x 2)
You are going to want to slowly raise the gain until you get to somewhere just below 24.4 on the DMM readout, that is where you are safe at 80% volume, if you max out the HU you will be clipping again.
Your friend doesn't know what he's talking about, I'd strongly advise not taking his opinions.
Note: this equation is for 300 RMS, that's kicker's rating, I do not recommend going much higher you will risk blowing the subs.
Your friend should come on here and give his audio expertise against some of the champion sq members.Then you'll see how much he actually knows!
A DMM won't sense clipping.
If his head unit is clipping and then he sets the amp off that at a level that its clipping hes just going to make it worse.
BUT I have used the DMM in the past and for what hes doing now I can agree it is 10 times better than what hes is doing currently.
Truth is what everyone here said. Once you set your setup to what it SHOULD be set too, you will hate it. It is going to be very quiet and just not anything to talk about. 300-400 bucks you could get a sweet 1K used amp and a decent 15 and run it and it would blow you away. Build a quality box and just toss your current stuff on craigslist.
Papa geno, what is a 1k amp?
Does anyone have a 50 hz signal?

I have smart phone, I can play a mp3 through phone and or ipod.
I thought the amp was capable of 300 rms per sub because that is what audioban told me when he looked it up
