I wouldn't be talking about my little 3 in a public forum if i was you.

 

which battery would be better knowning this is canada... the kinetik battery only has 750 CA but this motomaster eliminator battery has 875 CCA

which one would be the best buy to run a 2000 rms amp to? and still give me a start in the winter?

the little 3? Where are these spots usually located on a domestic unibody? I can't spot any obvious areas.

 

About 3 or 4 small AGM batteries would be nice to replace a capacitor.
