Beginner question - hope its not too late

[tuckj]

Allready installed:

1- 500/1 jl amp & 2 12w3 subs (custom box I made myself - looks good)

1) The amp is rated at 500 watts continous

2) The optiumum range for eash sub is 250 watts.

3) Subs are wired in series = 4 ohm load

Everything lite up nice - sounds good.

I was reading your forums and found many postings on "gain setting" and decided to give it a try.................when I reread the instructions, I started asking myself questions I can not answer.

Serous question - is it ok to assume that I can run 2 subs (rated at 250 continous) on an amp that is rated at 500 continous and not harm the subs? This is an assumption I made.

Please tell me what voltage I need to achieve when setting my gain - there are 2 subs in series

Thanks a million

that amp is pretty much a perfect match for those subs. 250 wRMS x2 = 500.

check out JL audio's gain setting tutorial. they will tell you the exact voltage you need for your 500/1.

Set the gains for the amp so it does not clip to 500 watts, yup, you could actualy push those woofers with an even larger amp than that probably.

Thanks SSS 18734 - your quick reply is appreciated.

I am familiar with the JL tutorial.....................so if the chart says that the 500/1 @ 4 ohm imp = 44.7 volts. Is 44.7 my target?

Thanks
