Ok I have a slight problem. When I first bought my 89 IROC and put the stereo in it I could play it for at least 3 hours at like 3/4 volume and still be able to start the car (see components in signature), and when I used to have my 64 Falcon with an almost identical setup the same thing was possible, but now it seems i can't do that any more. If I run the system for more than an hour I can't start it. Just sits there and clicks. Anyway I replaced the Battery when i bought the car a year ago with a DuraLast with 800+ cranking amps from autozone, and then I replaced it again 2 months ago (lost water). So I'm at a loss here. I know that my alternator is not fully up to par, I had autozone check it for me and they said it was charging at like 85% or so, but I figured as long as when i'm driving down the street at night with the lights, fog lights, heater, and stereo going and when at a stop the bass hitting doesn't dim the head lights then i'm fine. Anyway any ideas would be appreciated. Thanks in advance and sorry this was so long.

Your not only killing your battery, your killing your amp too. If you want to continuously listen to your tunes with the car off, then you'll need to install a second battery.

A second battery will not help. Especially if you have Orion HCCA Amps. They are not regulated which means they will run at whatever voltage they see between 12V and 14.4 Volts. These amps like 13.3 to 14.4 Volts otherwise they will get hot!!! When you run your stereo whith car engine off you are running your amps at 12 volts or less depending on the condition of your battery. The HCCA Amps are pretty bullet proof but they can be damaged.

You should not play your system loud for very long with the engine off.

It sounds like you having a problem with getting a decent battery. Dont buy cheap batteries. They will only cause you grief. For the best performance buy an Optima Battery and buy a 1 farad Capacitor. You should also get your Alternator rebuilt.

Anyway, how does that 10" Alumapro sound?? I hear they are the Bomb! With that HCCA Orion Amp I bet it hits pretty damn hard.

I have driven 4 12" JBL Pro series in Parallel on a HCCA225 (400watts). They kick major a**s!!
