I have a pretty simple question- I did a little search not much help, and I dont trust many guys at the lil car audio shops here. I want to put in better sub, maybe like a W7. I have seen a few on this site with that done, but they had a separate optima battery. How does that work, when the battery dies, is it hooked ot the alt or do you remove and recharge it separatly. Is it needed or would aalt recoilling/ rebuild (high volt) be a better option. Thanks for the help in adv.

 

Its going to depend on your overall system. How many amps are you using right now? What is your current car battery? any info you can give will help.

 

What kind of battery are you running in your car now? And let me get this right, you want to have one 12? a w7, correct? What type of amp. I would recommend if you're only running one 12, to get an optima for your main battery. I just got a yellow top deep cycle. And I'm running 2 x 12's. Also, if you are concerned about the load, throw a farrad cap in there. I just picked up a 3 farrad capacitor with a built in fuel cell.

 

That sounds liek a get plan, b/c I didnt think i would need two batteries on my car for just one 12. I am going to go with the JL amp if possible the price is alil factor I hope to get it for less than 6 new. But thanks for the help
