Need ohm/rms Answer - ASAP

[guitarman626 10+ year member]

Ok, i'm powering three 4-ohm DVC subs, each with 300watts max RMS.

So I obviously need 900watts RMS total from an amp.

I'm going to wire my subs, bridging them down to my amp. This will give my mono amp a 2.7-ohm load. (as shown in this diagram)

I have two mono amps in mind, one with 1000watts RMS @ 2-ohms, & one with 900watts RMS @ 2-ohms.

My amp is going to have a 2.7-ohm load, causing the amps' 2-ohm RMS wattage to drop slightly from the estimated max.

This means that the 900watt RMS amp will not fully power my subs, while the 1000watt RMS amp probably will.

The 900watt RMS mono is $100 less than the 1000watt RMS amp.

So my question is, will the 900watt amp likely show definet, noticable difference than the 1000watt???

If its not going to be a big deal, and you probably wouldnt be able to tell a difference, then im going with the 900watt RMS mono.

Thank you for any replys!

no it wont be a noticeable difference....what exact 2 amps are they, and how much are you looking at spending?

no, not that noticable

 

[benchambers80]

depending on accuracy of ratings obviously

The 900w rms is a kenwood KAC-1904D or somthing like that, and im not sure what the 1000watt rms is, but I was just at best buy and i couldnt decide which one.

anyways, the kenwood is $300 and the 1000watt rms is $400.

so you guys think i should just get the kenwood?

neither one of them are probably putting out rated power.

Dont go to best buy //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

well ive read several reviews on the kenwood, and ive heard mostly good things; and even with a lower rms that they say it can push, i should have atleast 700watts rms at 2.7, dont you think?

plus $300 is a pretty good price, or isn't it?

x2. I work there, and I'll tell you first hand. Stay away from the car stuff. It's a waste of time, and money.

saz-1500 will be @ 350 shipped, and you will be much happier, and will have a quality amp

If your willing to go used you could snag a hell of an amp for half that price.
