oibone what year is your car and what size alt do you need 180 or 200amp? Up the wattage meaning a larger amp.

between the IDQ and perfect either way, but save your money and get the ID Max, if you are looking for one, I have one sittin in my garage.

Here is a guy that test benche a 1500D

"now... to finally settle the questions about where the brutus bx1500d sits in terms of power output.

1172 rms at 12.5 volts at 1 ohm with 126A current draw.

will it hit 1500 rms at 13.8? i don't know. but with 126A of current draw to pull 1172w out of this amp it doesn't matter to me. lol. i don't have the big 3 done."

That's a big current draw. 128 amps damn. That's not that great.

What can the stock alternator produce? 80 amps? And, at about what wattage (rms) will you need to upgrade your alternator?

[eddiem67]

Well lets say your stock alt is 100amp, and you add a 500 watt amp, that is an additional 50amps of current required, so you would need a 150amp alt. The stock amp is already supplying the need of what the car has. So basically add up your current draw and add it to the stock alt, this will give you a ballpark requirement of what alt you will need. the largest factory replacement you can get is a 200amp, anything bigger will be a larger case and may need to minor modifications.

The max amperage of the alternator isn't the most important factor. Quite often the larger alternators recharge at a much slower rate. Look into every detail of the alternator you're going to buy. From what eddiem67 wrote the 1500BD can only produce roughly 1300 watts and draws a hell of a lot of current. What you saved in buying the Brutus amp you'll spend in electrical upgrades...

[oibone781]

not all amps draw out the same current, just because it is a 500 watt amp doesn't mean it is going to put 50 amp draw on the alt. The rockford 1001bd puts out nearly 1200-1300rms and only has like a 60 amp current draw on the alternator...

[mauibuilt59]

Is a higher current better? Because I know in home stereos, the high current receivers are louder than the regular current ones. Does the same apply in car amps?

[OHWJaJae]

No. Higher current per watt just means it's more ineffecient.

[finese1]

That's why I was stressing the inefficiency of the amp. Power is cheap but quality and power isn't. What is your goal when you guys buy amps just bang for the buck low THD% or efficieny? Or maybe a total package.
