Advanced Discussion

I'm going to use this to bring up questions I have or to discuss certain things I've thought about so I can get a better understanding of it. Please be patient with me though as I am still quite young. The first thought I have is about inductance. Does the cemf have much effect in the range of subwoofers? What about inductance modulation?

Ive had my 1 rfr3110 in a regular square-ish prism shaped ported box no polyfil and at first all I wanted was boom. At higher volumes, theres a noise that I dont know how to describe, but I think its just reverb from within the box or something. Now im tired of boom and really want smooth bass, just LOUD smooth bass. By the way, its in a chevy lumina trunk, stock battery, will have 200A alt, 1x dub8001 (i know, not the best by far...). I have another sub (same kind) and amp (same as the amp im using) and im just saving up for an alternator, so in the meantime Ive been thinking of boxes that will help boost sound quality and eliminate standing waves. The point for this top…

I need some help with the best way to hook up my subs. Right now I have one of my Punch P2D210 sub hooked to the B side and the + to the + and - to - like the manual said to do. Would I be better hooking the Sub1+ to the A+ and Sub1- to the B- ? With two subs Punch (P2D210 x 2) am I better off hooking Sub1 + to A+ and Sub1 - to A- / Sub2 + to B+ and Sub2 - to B- OR Amp A+ to Sub1 + / Sub1 - to Sub2 + / Sub2 - to Amp B- ? OR if none of these are are the best way then just let me know the best way. Thanks for the help. Picture of current single sub ( + and - are on B posts)

I tried to read the threads on how to make a slot port and etc. etc. I tried to use the ones on the net, but people keep saying they are off. So if you happen to have microsoft excel, you can use this on and plug and chug some numbers in to get your required port length. This is based off the equation on JL Audio's site and it also takes into account End correction. If anyone has any input or if the JL Audio equation is wrong, then let me know, I just wanted to do my port right. http://www.uploading.com/files/CFXVZ5QA/Sl...ulator.xls.html
