1500 RMS too much?

Will my old 4 guage power wire be enough for the BX1500D I'm getting? Also do you guys think my 120amp alternator can support it?

I'm fairly new to car audio to, but im sure 4 guage is a little small, I've got a 1000 watt RMS amp and run 1/0 guage. My altenator can keep up fairly well in stock form at higher rpm, but it sucks at an idle. Maybe somebody can back me up here.

What amperage is your alt?

THE BX is the brutus hifonics right? if so they are rated below what they say they are and 4 gauge should be fine.

dont look to hifonics for that then.

try kicker, directed, orion, etc etc etc.

yeah all those brand Johnecon listed. you will see a difference in price too. that brutus is like 200 max new. the kicker 1200.1 is around 300$ yeah it sucks i know i had one

****it, well I know kicker's are underrated as I have that KX600.1, but I thought Hifonics were too... I already payed for a BX1500D... SOB

their not THAT overrated like audiobahn tho

that bx1500 will prob make 1300rms actual watts ease and 1500rms with a good electrical system

4 guage should be fine. Look into changing the wires under your hood though with 0/1ga and you should be fine with your existing alternator.

K cool thanks. I'm pretty sure the wiring under the hood is pretty big already, but I will look tomorrow. (My car has a lot of shit to power with the air ride system, power seats, windows, locks, sun roof...) Then again all that probly doesn't need 1500 watts LOL

Oh well I guess that's not too bad if I'll be getting 1300 rms or so, that'll push the XXX, I still will feel like I'm not getting all I could be though //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

actually I think your running 8ga from the battery to ground and Alternator and 10-12 ga on your engine to chassis ground. Something to look into. Will help your car all around charge better

Oh, and thanks for that link rukus, I think I'll do the big 3 tomorrow, I thought it was a bunch of expensive shit... but it's just wiring //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Ask Jmac for the technical explanation of it, but you wont hear a difference in 1300 and 1500, so dont worry about it.
