Finally back to car audio.

Well, after being without my own personal vehicle until today I have been disconnected with car audio.

I am purchasing a Mazda 626. My budget is low due to being in school most of the year and wanting to pay of the car payment in 3 months along with student loans etc...

I'm not setting a specific budget as I can always just do the high end or low end.

As of now the plan is for

1 AQ SDC 2.5 12"

Lanzar Opti6.1

SS PX1.1300

SS PX2.420

The HU is a Sony that is a few years old. I thought since I already have it and since it works why not..

Wiring will be KNU Fleks 1/0

Any better Idea for 600$ total or less WITH wiring? Or maybe should I only do one part at a time and spend a total of a few hundred more.

For a daily setup no upgraded alt and standard size class battery for the car, I should be okay with around 1000 total watts? that is 80ish amps peak. Basically what could I push it to? I believe the stock alternator is 80 or 90 amps.

So basically, what is an estimate for continuous draw, and what is a battery capable of recovering from when your output surpasses maximum input.

Sorry for the long post, thanks for any input!

Depending on a number of factors, you can generally plan for 1,000W - 1,400W RMS on a factory charging system with an 80-100 amp alternator. It would be wise to do the Big 3 upgrade regardless. Some of these factors are the efficiency of your amplifiers, if you're going for lots of bass or just want it to sound good while being able to crank the volume, and how well you complete your power and ground connections. You won't know until you get your equipment in and running because the math makes it seem impossible for an 80 amp alternator to power the audio system and the car.
