I am thinking about picking up a 18" Kicker, looking to aim for 4k because I hear that is the best for daily use.
First off lets talk about H/O alternators
I hear something like alternators having 'dual' or something like that in them where they put out A LOT more than normal ones do?
I am looking to dedicate a alternator to the Sub or should I include the speaker amp on it too?
I hear a lot of people arguing you will never get like 200-300 amps at idle, makes sense to me, hell even dropping my truck into N I can see the voltage meter go up a tiny bit. But I was wondering what a good alternator I should get to power roughly 4k(I know I won't be running these straight off the alternator)
Think you have to get isolators or it won't charge each battery properly correct?
About how the power goes, will it always use up the alternator first, then start draining from the battery? Or can I make it so it just drains the battery and the alternator charges the battery? Not sure exactly how the power works in a car. ATM, I don't need an explanation for this, just an answer/tell me what is best to do.
Now for batteries
I see some people with these subs or other ones with higher voltage batteries, like 16V ect. what does this do? Is it better to do it like this?
I dunno if any batteries come with volt meter, but it would be nice to see how much my battery(s) have left in them, where would I put this in the circuit for more accuracy?
Looking for some recommendations for batteries, and how many you guys think I should have to run these subs. Of course I am ok with turning them down a little to let the battery charge, I don't want my ears to blow up, I won't be even pushing the 4k much I don't think, I just want it to be able to take that much occasionally for a decent amount of time, not some batteries that are going to die from being discharged regularly.
Not really that much wiring questions, just maybe what gauge I should run from my Alternator to Batteries, and what speaker wire I should use?
