ported box for 2 15" audiopipes

well going from 135 to 300 each will get you at least 2 or more db's.

 

the big three in some situations can help...it can raise the voltage that your amps see making the amp work not as hard and more efficient

I'm loading up a couple vids of the 12W6 and 400-500 watts

one is a 10Hz Tone....sounds like a helicopter lol


the other is a 35Hz tone...both are the with engine off amp seeing about 12.6 volts

 

Duralast Gold Group 65

 

well mine is like 1000CA and i think 875 CCA

I always say just get the biggest battery you can afford

reserve capacity is good too...i forget

Here is 10 Cycles


Here is 35 Cycles


Here is 40 Cycles

 

yeah...fairly simple.

read the sticky about adding another battery in the electronics section of the forum

 

why would you do that??

if it fits in the battery tray than the swap should be simple.

Most factory batteries are just big enough to start the car and run some accessories...unless you have a big truck

 

really either batteries will work fine

the only major difference between a starting battery and a deep cycle is the thickness of the plates.

I'd go for the yellow top though...it is warrantied for audio use also.

i'd keep the battery you have now and add an optima in the back
