Setting My car Amp's gain (already read the tutorial :D)

[bimma85 5,000+ posts]

Hey guys, quick ? here. I went to set my gain earlier, and threw a couple different test tones on. With them I got different voltages. I saw most people that mentioned the freq. they used they said 50hz. I saw this is what JL had on their site. I just wanted to make sure this is what I wanted to use. Also, all the test tones on the mention website in the first post of the gain tutorial... those are at 0db, right? Have another quick question. I have a MTX 1000d(old version of 81000d 1501d etc.) rated at 1000 watts at 12.5V (1158 i think on birthsheet) and rated 1500 at 14.4V. I don't see how 2 volts will add 50% power is this even correct? Anyways I have a 95 bmw 325i and I doubt its running more than prolly mid 13V. What would you guesstimate my power at?? I was thinking about 1300 watts. Thanks in advance e1 has been quite helpful the whole time i've been here. FYI I did search this out but did not find a clear yes or no answer .

For subs; yes, use 50hz.

Yes, you need to use a 0db sinewave (test tone)

Too lazy to do any math....but on a mid 13V system, I'd give you ~1300w

35-38v? Anyone else sure on this //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif. Im getting about 51Vs. 1300x2=2600 51*51=2601.

I have always used 60Hz, because that is what the AC voltage here in the US is
