rpm drop.

ok, i installed my L7 and, i was playing it lud and, i noticed that my rpms dropped a couple hundred. the lights in the cab dimmed and, my head lights dimmed. i have heard that caps do and, dont work. i do have one in my room, laying around. i do not have the big 3 done. my qestions are, should i go ahead and, order a new alt. or, how about a yellow top? i just have a regular old battery in there now. should i replace it with a yellow top or maybe get two yellow tops? new alt? i dont have a ton of cash so yea.

thanks for the help.

i think ill do the 2nd battery then new alt. this brings across another question. with a 2nd battery i know my the frsit battery i run a positive to the new one. now do i run a newgative to the first to second? then go ahead and hook up my ground or, do i need to run the negative between the batteries?

U want ur negative on the main one grounded (hopefully u did big 3 already). Then run a 2nd cable from the negative on the main battery to the 2nd bat. Or if u dont have the space to run a 2nd line from ur main bat u can just ground the 2nd one somewhere else.

Also dont just get the 2nd bat. Make sure ur ready to get a new alt as well. Unless ur playing ur music realtivly low alot.

will i notice a difference in performance? such as it being louder clearer?

Should, because when ur lights dims it means there's a voltage drop. So with everything grounded and the upgrade ur amp should be seeing a current thats alot more constant, so it would be able to put out a more power cuse the voltage isnt dropping. I can't really say if it'll be louder or clearer, but ur amp should be putting out more power where ur voltage use to just drop.

will it be night and day better? no but you will notice your amp not getting hot and your stuff wont dim nearly as bad. if you had a term lab you could see a difference in your score. http://www.kinetikaudio.com/manuals/khccells.pdf on page 8 has a diagram of an added battery (i dont have a screen capture otherwise i would copy and paste it)
