Hey all 
´
First of all I can tell you what I have in my car..
2x Infinity Kappa 12" 1400W Supwoofer.. I have
2x Infinity Kappa 6" x 8" 2-Way 300W Car Speakers
2x Infinity Kappa 3-1/2" 2-Way 105W Car Speakers
And the Amplifiers are:
1x JBL 700W 2 channel for the Sub
1x JBL 600W 4 chennel for all the speakers..
But the problem actually here are the subs, they take too much power from the main battery in my car.. I'm going to buy battery, one of those batteries whicn gather the restovers from the main battery.. So that my Car Audio System doesen't directly use electrisity from the original battery.. But I don't have so much understanding about batteries and electrisitiy.. So i'm not sure whish of these bettries I shold buy.. But I'm thinking of an Optima Yellowtop 5,5 75 amp and with an start amp of 1125 EN.. But I'm not sure if one of those is strong enough to provide electricity for my car audio?
