Uhhh....Infiniti is made by Nissan. Just like Lexus is made by Toyota and Acura is made by Honda. I've checked before and Infiniti wanted almost $800 to replace the alternator in my car. Hell, I've done it once or twice before (shoddy wiring along with a capacitor wired up wrong caused the alternator to try to charge up a completely dead battery) and I am now able to do it within 20 minutes. I am going to be adding some more accessory lighting and an air-ride suspension system so it may just be worthwhile to get a H.O. alternator now.

Oh BTW....here is an animated gif I made of my car at night. Enjoy!

dude, that is awesome. I need to see your ride sometime because I am curious about your neons. Where is that Rite Aid at? Do you live outside of portland?

That Rite Aid is in Milwaukie (SE Portland) area. If you have any questions or wanna see the neon lighting up close, just e-mail me at q45guy@attbi.com //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

ok. now i am confused about this whole electrical problem now.. I unerstand that power equals voltage x current.. however, is this for max or rms power?

example.. JBL 1200.1.. 120 amps worth of fuses in it (i believe it pulls 114 at max).. so, 120 x normal volts from battery, 12.8 = 1536 W.. now, if the amp is rated to put out 1200 watts, and this formula is for max power.. then, the amp is definitely not putting out 1200 rms..

is there something that i am missing??

Efficiency = 1300/(114 x 14.4)

Efficiency = .792 or 79.2% //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Ok, so if you round that to 80% effecient.. then, 80% of teh 1300W is 1040W.. so, a 80% effecient amp ratd at 1300watts is only pulling 1040 watts rms?

An amplifier (Amp A) that is rated at and does 1300 watts and is 80% efficiency would put out 1625 watts if it were 100% efficient. In other words, Amp A makes 1300 watts with the same amount of current as the 100% efficient 1625 watt amplifier //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 

Voltage x Current x Efficiency = Power

ahh.. now i see... thanks Jmac..
