HiFonics BX1500D Current Draw

[BonusBobo 10+ year member]

I have a 1993 Ford Explorer with a stock alternator. I want to get a bigger power supply than what I have now (~800W) for my brahma 15. I was thinking a HiFonics BX1500D because it's somewhat affordable on ebay.

My question is regarding the current draw and the strain I may put on my electrical system. If I got one of these, would I need to upgrade my alternator or buy a new one? Recommendations on products, or ampere levels are welcome.

Find out how big you current alt is, then email johns@maxxsonics.com and ask him about the current draw of the amp...

ok, that helps. But how much more amps do I need for other accessories such as my 4-channel amp (usx4065), headlights, etc.?

4065 - probably around 20 or so

The rest of your cars electrical system - I'd say around 40 or so, to be a little generous

I emailed him ,100 amps at 1 ohm, for anyone that else wants to know

Who's "him"? Is that a HiFonics guy?

Thanks a lot, though, that helps a good deal.

yes, John@maxxsonics.com said that

1500 + watts output with only 100 amps of draw is impossible...

even if the amp was 100% efficient.. still be a bit over 100 amps..

I figured more like around 120. Steve (ss3079) said 180A, which I didn't expect at all.

180 may be the MAX draw, which is not always the case.

yeah, understandable. What does your 800.2 do at 1-ohm? I looked on the avionixx website but still don't really understand.

its not 1-ohm stable. At 4 ohms, it puts out around 900-950 watts. Hopefully i'll get around to benching it some day. I'm not sure what the current draw is, only that my lights don't dim //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

That's basically all you need to know though, right?

OK guys, I think I'm gonna buy it. Speak within a day or two or forever hold your peace.
