Hey everyone, I'm looking forward on installing a sound system in my 04 FX35. Got power acoustik vertigo 1,800 and another vertigo 2,200... I'm still on planning mode and looking information about what battery and alternator I should get... So far I'm looking on installing AGM battery but my question is why I shouldn't have it combined with my stock battery? I'm thinking about putting an isolator also.
Any suggestions and opinions are welcome. Just get a high output alternator or 2 of the same batteries or one AGM battery with the stock battery and a isolator?
