hi guys, can anyone tell me if i should upgrade my stock battery if i am putting in a audio system? my setup will be nothing too powerfull just a JL 250/1 and a rockford P4004 which ithink is 200Wrms .. so total of 450Wrms comin from the two amps.. I also have coaxials,components, and a alpine deck (dont know if this info is relevant). I am sorta on a budget and dont want to spend an extra $100 on a good battery so just wanted to know if it is necessary??

 

With the equipment you've listed, upgrading wouldn't be required at this point.

 

no need to my friend.

 

I would say no, but be forwarned that RF sucks a TON of juice for minimal results..Not exactly efficient friendly.

 

hmm.. really.. no wonder i hear that RF's output is usually higher than what they say.. I am also concerned because i have an aftermarket warranty and if my alternator or any electrical go.. they will blame it on my audio system.. so i am worried about that too.. another question..with my setup .. how long can i play my music for with the engine off? i know i shouldnt do that but if i am waiting for someone only for few mins.. should it be fine? or the engine always has to be on? thanks for your advice guys

 

I'm running a what is in my sig....I have listened to the music with the car not running for about an hour before without the car dying. The real test will be to go to the local drive-in movie theater and see if I can listen to the whole movie.

 

my RF power 451s amp sucked a crapload of juice from my 3rd gen...enough to cause a bit of dimming. the amp only put out ~480 bridged.
