Need advice on battery / wiring.

Ok, i have completed a Big 3 upgrade using 0/1 AWG and im using my stock alt (120 or 150amp) in my 09 Fusion SEL. Im running 0/1 AWG from under my hood to the trunk for both + / - lines. I will not be using an isolator as i dont play my radio if the car isnt running (heard its fine if you dont use it while the car is off) It will be ran to a 2nd battery in my trunk that will be there just for some extra juice. From the trunk battery it will go to a 1farad Rockford Cap than to my amp.

My question is will the 2 below batteries be sufficient for my everyday car needs plus the stereo?

Amp - Rockford Fosgate t1500bdcp
Sub - Kicker L7 15"

Under my hood will be this battery -
Kinetik-HC1200

In my trunk will be this battery -
Kinetik-HC600


Now it appears to be sufficient, but i dont understand the amp hours stuff, but im looking for long term use of these batteries (2yrs+).

Amp-hours (AH) is the total capacity rating of the battery. Standard for all AGM batteries. Don't worry about that. The Kinetics are rated to total amp load on your system.

@neo_styles ; so than those 2 batteries should be sufficient for my needs? also, thnx for the headsup in my help thread about posting :)

No prob. Noobs helping noobs = flames but I'll take my chances.

I can only speak from my knowledge of basic electrical theory, but I could forsee an issue using those differently-rated Kinetics without an isolator. Since they have different capacities, you could end up with one acting as a load on the other which could be bad.

Please correct me if I'm wrong, anyone

Here's where I'm coming from. Dug this up from a random page online:

It will definitely reduce the effective capacity of the set as a whole, perhaps not quite to the lower of the two ratings, but very close. You will also be over-dischargeing the lower capacity battery, which isn't good.

A similar argument applies to charging. Overcharging a cell will overheat it, reducing its useful life.

@neo_styles ; so if i get an isolator for the above batteries i should be fine?

Yes

Lose the cap and you should be fine.

Many of years and many of batts and I have never used matching batts in a setup.. Issues = 0... Isolater is not needed unless u plan on playing with car turned off. ^^ loose the paper weight.
