[QUOTE="dirtbagz89, post: 4903615, member: 578535"] I found this companies website that sells amps...they explain how to determine if your vehicle's alternator can provide adequate current to the amp. [URL="http://www.quantumaudio.net/amperage.htm"]http://www.quantumaudio.net/amperage.htm[/URL] Now using what they say my setup would be like this: 2008 Pontiac G5 stock alternator = 105 amps 105 divided by .40 = 42 amps available Amp current demands: Keep in mind I am looking into buying 2 Dual 4 ohm 12" Alpine Type R subs... both are 500 RMS for a total of 1000 RMS. Now I have a couple amps I'm looking at...my budget is about $200 [URL="http://www.sonicelectronix.com/item_11795_Kenwood+KAC-9104D.html"]http://www.sonicelectronix.com/item_11795_Kenwood+KAC-9104D.html[/URL] 900 watts wired at 1 or 2 ohms...so 900 rms divided by 1800 peak is .50 (50%) Fuse value on amp = 30a x2 = 60a 60a x .50 = 30 amps [URL="http://www.sonicelectronix.com/item_8177_Kole+Audio+KX1-2000D.html"]http://www.sonicelectronix.com/item_8177_Kole+Audio+KX1-2000D.html[/URL] 900 watts wired at 2 ohms...so 900 rms divided by 2000 peak is .45 (45%) Fuse value on amp = 30a x2 = 60a 60a x .45 = 27 amps [URL="http://www.sonicelectronix.com/item_8403_Kole+Audio+KX1-3000D.html"]http://www.sonicelectronix.com/item_8403_Kole+Audio+KX1-3000D.html[/URL] 900 watts wired at 4 ohms...so 900 rms divided by 3000 peak is .3 (30%) Fuse value on amp = 30a x3 = 90a 90a x .30 = 27 amps So is this website correct or no? So I would be alright buying these amps using my stock alternator? [/QUOTE]
