jl 12w6's 500/1 amp

i HAVE 2 12W6'S IN A CUSTOM BOX  AND 500/1 RUNNING THEM, THEY ARE IN A 96 CAVALIER.  i WAS WONDERING WHAT SETINGS ON THE AMP i SHOULD ADJUST THEM TOO

I need help setting the freq, "Q" and all the other settings

yea that amp is a doozy eh? Setting that amp is quite a task. Finding your center frequency, and your 'q' and all that has an awful lot to do with the sound *you* like to hear... this really isn't something we can just tell you over a message board especially with the amount of information you've provided. The "q" is how steep the curve is that represents your frequency response, the "center frequency" is where the "q" is the highest.. You need to play with this page a bit then post back with specific questions. http://mobile.jlaudio.com/support_pages.php?page_id=144"I'm finished!" - Daniel Plainview

so basically I have to mess around with it until it sounds good?

..thats not really what I meant. You are supposed to study that eq page so you can *understand* what those controls do and how they effect your response curve, then you can understand how that in turn will translate to sound in your car. To be honest, one of the most outstanding features of that amp *is* that onboard eq. I mean, for a mono-amp that thing is sick. Perhaps you overpurchased. Either way, the general idea is to get the flattest curve possible... generally, flat frequency response sounds the best. Real even, tight bass-lines and what-not. But the acoustics of different vehicles greatly as does the way subs sound in trunks. So that eq lets you compensate for that by outstanding output control. "I'm finished!" - Daniel Plainview

so instead of having a big peak for the eq, I want it to be flat as possible?

..right... but within what is realistic for your driver, enclosure, and power range. A sealed box has a different curve than a ported box... which... oh man. I could type for like three hours off that statement. In terms of w6's, you ought be able to produce a curve that is + or - 3dB from 30 - 80hz... what *I* would consider 'flat' ... I had extremly good results with a 13w6. What kind of "custom box" do you have? If it is ported, what frequency is it tuned to? What head unit (exact model number and URL if you could) are you using? What subwoofers are you using, again, exact model numbers.. "I'm finished!" - Daniel Plainview

how do I figure out what freq it is tuned to. The box is sloted if that is what you mean by ported. Do I take the measurements and divide it by something? the box is 36w x 14tall x 19deep, the slots are 2 1/2 wide x 12 tall. My headunit is the kenwood excelon kdc-x789 if that helps any? thanks for all your help

Whoa. That works out to like 5.5 cft. I'm guessing your slot ports and the wood take up a large portion of that though. What kind of material is the box constructed with? Thickness? Just for fun, if you can tell me how LONG the ports are, I'll figure out the frequency for you... here is the formula if you're interested. Then we can work out a center frequency and a q setting for you. Or at least I can take an educated guess. That's a very nice head-unit. 5v-preamps should have your gain setting no higher than half-way up... especially in a box that big eh?"I'm finished!" - Daniel Plainview
