I have a 10 inch 800 RMS sub @ 3 ohms.

had an audiobahn 1801x amp but sold it.
now i need a new amp. any suggestions???
i tried the alpine m500 which is 500x1@2ohms and it isn't as loud as the audiobahn which was 560X1 @ 2 ohms of course the alpine is a class d and the audiobahn is a/b.

any suggestions are appreciated.

Class D and Class A/B make no difference in how loud things will get.. this boils dwn to a matter of how much U wanna spend.. a JBL BP1200.1 would push about 800Wrms exactly at a 3ohm load..

THANX,

that amp seems perfect for my application. appreciate the help.

btw. why am i still a newbie. i've been a member since november last year?

I never look at member status..some diamond members are worse than newbies... you are who you are..not what a ranking on this says ..

i've heard class d amps have a better chance of frying than a a/b amp is this true? also heard that you should NEVER hook up an amp at 1 ohm even it it says its 1 ohm stable. why do they make 1 ohm stable amps then?

So, I downloaded the manual for the JBL 1200.1 and noticed that it can draw 117 amps.
How will that work w/ my stock alternator?

YUp..music only represents a 33% load with most rap and dance.. about 45% with Bass CD's..Also, you'll only be putting out 66% of that as you'll be wired to 3ohms..

thanx again.

still, 25-30 amps is a decent pull for our alternators... you gonna be using an amp for highs?

raoh

yeah,
i have 2 a/d/s 250mx's amps pushing front components and rear coaxes. plus the jbl 1200.1 when i get it, and i'll have 1/2 farad cap to start plus i'll get more if i need it later.

I figure i'll run the amp till it dies then i'll get a bigger one btw any one know where to get a good alternator?

before you go and bye the 1200.1 what kinda sub is it?
it could be some pyle thats says it can handel 800 watts but can only handel 250

raoh

its an Audiobahn alum10x 800rms. not the best, but not exactly crap either.
i'm sure it probably can't handle that but i can always turn down the gain or the nonfader on my head unit.
personally i think that my sub @ 800wrms will be too loud for me, but its nice to know if i want to thump...I can.

LudlamTheory

go with 1 farad

raoh

i'll probably go 1.5

since i already have a 1/2 i'll just buy another 1 farad.

also, do you think one company's caps are better than anothers?

i mean its just a capacitor right, how do you make a crappy cap?
