Literally out of your mind and your buddy above you just tried to tell a guy that wasn't getting proper air exchange to his subs to fire them in a different direction.When I say something, take it to the bank. Don't think I'm guessing about it. Don't bother referring back to something you read on the internet somewhere. Write it down and remember it.I was one of the first 25 people to sit in the buick Grand National. I helped build Lanzar's white explorer. I put together transmission line box designs still being built today before CAD was being used to do it.I'm only saying this once because I was there when the book was written, and I'm not arguing about it so this is the one post I'm making on this:You are misusing the capacitor. It's hard to properly use something if you don't know how to use it. It has nothing to do with what voltage your system runs at, that is what your battery and alt are for. Capacitors are filters. Farad caps are useless to bass heads and were never intended to be used with any type of SPL/DB Drag style system. A capacitor does not supply constant voltage to the system, that is what the alternator and battery are for. Farad caps are made for people who play quick, sharp, punchy music such as rock for instance. The capacitor absorbs the initial voltage spike from the amp which is very quick. The capacitor charges back up and supplies the system on the next jolt. It is not made to supply constant voltage needed by the SPL vehicles. It is only for micro bursts which have nothing to do with how big your battery and alternator are. We are combating an initial bouncing spike.Voltage spikes have a "bounce" to them. They go negative in voltage, then back to positive. The only way to absorb the negative is to add a capacitor. The capacitor absorbs the negative side of the spike. The flip side of the spike is a potential surge on the other side of the bounce. *If this were a digital circuit we'd use a de-bouncing switch to avoid false triggers.The problem comes when trying to tell a bass head what a capacitor is for. It's an SQ thing, don't worry about it. SQ systems (and I mean real one's not "look I bought an EQT") need solid voltage and no line spikes which can induce noise into the system.A good rock and roll setup like the OP wants, will do well with a farad or two in line. OP, Have fun and enjoy! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif</blockquote>
