Rule of thumb thread.

[Sanitarium]

i watch my voltage

if i drop below 12.5 volts, time for another battery, if my idle voltage drops from having to charge batteries, i add an alternator. if i want to be able to burp at 14+ volts, i add even more alternators. remember unless your alternators can supply enough amperage to run your vehicle AND your amps with overhead, then your voltage will never stay in the 14+ volt range, you are at the will of your battery bank at that point. Adding more batteries can slow down the drop though.

0.75-1.15 for a medium range or lower 10

1.0-1.25 for a high power 10

1.0-1.5 for a medium range or lower 12

1.25 - 1.75 for a high power 12

2.0-2.75 for a medium range or lower 15

2.5-3.5 for a high power 15

4.5-5.5 for a medium range or lower 18

5.0-6.0 for a high power 18

12-16 square inches of port per cube NET if within those specs

if going bigger with your box, you can safely base your port on a box within that range even if that means your new box has 10 square inches of port per cube.

oh

and peal and seal is so awesome that i built a nuclear bomb shelter out of it.

sundown nuthuggers are going to treat their great middle range subs as if their $900 neo subs with 4" voice coils

DC nuthuggers are going to treat their level 3's as if they're level 5's

AQ can't get low < lol

RF products are 300% markup at the dealer, stay away unless 50% off or better.

Kicker/rf/alpine/JL audio nuthuggers are usually the kinds of people who tell stories about their buddie's windows breaking out and hopping quarters 10 feet of the roof while doing 160 db out of the trunk with 1 15 on 1200 watts.

haters gonna hate

bitches gonna bitch

If you thought of it, someone else thought of it already.

T3 nuthuggers... nvm, everyone hates T3 - enjoy waiting a year for your subs.

Blowthrough tunnels like the lows.

Your thread's been done, don't matter what it is.

Any arguement you give can and will be ignored.

There will ALWAYS be someone offering you a ridiculous trade/offer for audio that you're trying to sell/trade.

i'll think of more later.\

edit: one more

Someone will take my post too seriously and get massively butthurt.

get a extra battery after 1500 watts

get bigger alt after 5k

Rule of thumb..... mods> you and i..

If you have a question about math hwk 2+2 and n8ball says 2+2=5 just written it down and move on
