i just ordered a JL Audio A1800 which puts out 1000 watts rms at 2 ohms.
which seems PERFECT for my 2 alpine type r’s which run 500 watts rms at 2 ohms too.
UNTILL i started to read the find print
it says 1000 watts rms at 14.4 volts
and 800 watts rms at 12 volts
im like DAMN i need to go check my car voltage
i go and check and to my dismay its rated 12 volts
so does that mean im going to be robbed 200 watts when i turn my system up to the max??
all the stuff is coming in the mail soon so i know im not going to turn it back. its just i really dont wanna spend another 500 on a alternator / battery upgrade or would i really need to do that to get the most out of my new system??
thank you in advance
i own a SUV 2004 mitsubishi endeavor if that helps out on car size or alternator size
when your car is running, the alternator is charging battery and if your alternator is working properly your battery will be 14.4 volts, but if your using your headlights or rear window heater etc your volts will possably be down to 13.7 volts.
You can get external regulators for your alternator that will up the voltage going to your battery, not sure on the cost of them, but could be a good idea to insure you are getting maximum performance from your alternator

you wont know the diffrence about it. Yeah if you spent 500 buck for new alternator it wont be a problem. And damn you should get JL 500/1 or 1000/1 it a little better then the a1800, because the 500/1 and 1000/1 dont matter what is the ohm or the volt is, it still give it max out put aslong the volt it obove 10 volt.

You won’t notice a 200 watt difference as it takes double the power just to get a 3dB gain in volume.
Besides, you can set the gain to get the full 1000 watts,
The purpose of the gain is to match the signal volts RMS coming from the source (CD player, etc.) to the input of the amp to prevent clipping (damage by over powering).
Here is a guide that will help you set the gain correctly http://www.datafilehost.com/download.php?file=6d26c621
You’ll need a multi-meter (AC voltmeter), Microsoft Excel and a way to burn an audio CD from an MP3.
If you don’t have Excel, use this link http://www.box.net/shared/nkkw1dhk4g
