?

Ok I have a triple sub enclosure the sides are at 1.14cu ft the middle is 1.4 how do I measure a reduction to had a 2x4 or what ever to bring it down to 1.25 or match the other holes at 1.14

Its on March 1st 6pm and into saturday

the 1st part of my test is a 97- to 100 minute kubadachi (horse stance) endurance

thats a long time in kiba..

Gonna be a long hard test.

I was thinking about doing the Big 3 and was wondering since my battery is in the trunk of my car..alternator up front if theres a different way of doing the upgrade..suggestions and or pics would be great cars is a saturn ion 03'

ive got 2 Type R 15s and Hifonics BXI2610d amp slames pretty hard righ now but want to see if i can get more power for the amp

ok the issue im having is my car would just die..i get power but the motor wont turn over.. i wait 15 to 20 mins then it starts right up its been fine now for a month but for the last 4 days in a row it has died on me..ive had it looked at and and tested (diagnosis) check and it said nothing wrong with the alternator, battery (brand new), starter ect. what else could it be?

I just got the hifonics bxi 2610d amp going to run two alpine type r 15 s (dual 4s)

the amp does not have an on board external fuse any ideas on if i should run a second one just for the amp it self other than relying on the fuse by the battery..if so what brand how many amp fuse..? thanks in advance
