no for real thanks alot it helped i was really confused about the whole second battery thing my other question is that i just replaced the alternator with a remanufactured oem one (short on funds) otherwise i would have gotten a bigger one or have had mine rewound. but my question is that if i put a second battery in the trunk (most likely a yellow top) will that be too much for my alternator to try and keep charged? (i have a large Red top in the front) also with a second battery would it help to run an additional 4-1/0 ga wire to the + terminal on the battery in the trunk? i was bored last night so i did the "Big Three Upgrade" i used 1 1/0 ga wire for all of the grounds and i put a 4ga wire from the battery to the alternator because that was all of the wire i had left i tried to fit two 4ga wires on the alternator but couldnt so i settled with one better than nothing i guess. i guess im just nervous to plug my system back in i dont wanna fry another alternator and battery and get stuck at sheets again for a half hour but i am going to remove the cap and just run my + wire straight to my amp for now. thanks for the help guys!
