I have a class d amp that is 650 rms @ 4ohms, 1300 @ 2, and 2000 @ 1. I was looking at getting 2 fosgate 15" power series stage 2 subs, because they will work in a ported box with 2.3 cubic feet of air space per sub and also because I see I can get them on ebay for around $350 each, but now after reading comments on various post on different sites, these subs don't sound like such a good choice. I want to wire the subs so that I get a 1 ohm load.

I have been looking at jl 13w7's also, but the cost for 2 is kind of high in my opinion. I have read some favorable comments about resonant engineering xxx model subs, but wow what high price. Also, have read some comments in support of adire brahma subs.

What I would like to know is what 2 sub combination(can be other brands) would give me great sound quality and high spl using 2000 watts and not a huge amount of air space, if I decide to compete?

Thanks!

First of all is this a true 2000 watt amp by a reliable brand? if not then more often than not you may get 500 or so watts out of it a quick way to figure it out is to multiply the fuse in the amp by 14.4 then multiply that by .8 this will give you a realistic rating based on 80% efficiency of the amp (I know someone will have an issue with this but I'm just being quick). Then before deciding on subs if this is a real 2000 watt amp your current draw on the car could be up to 150 Amps or so This is quite a large load which a stock charging system will have trouble with you should look at upgrading the big 3 (do a search here to find out what that is) and also look into a high output alternator to keep up with that current demand.

IMO....more realistic is taking the total fuse X 13 X .8

14.4 is hard to keep stable without some heavy upgrades

Also, are you REALLY looking to compete? If you were, you'd be willing to give up VAST amounts of space - (generally) necessary for huge output, especially with two woofers and "2000" watts. (What amp did you say it was, again? Audiobahn?) 4.6CuFt is a "not a huge amount of space" enclosure to you? In a '92 CIVIC!?! Did you know that the difference in output (SPL) between 2 ohms and 1 ohm will be less than 3dB? Did you know that 3dB is a barely discernable difference in either lowering or raising a system's output? By making that amp work as hard as it can, it's whole life, it's not going to last nearly as long. It will run hotter, it will make more distortion, it will have less control over the woofer cones by virtue of lower damping factor. Are you wanting vented enclosures? I see that you are... This'll REALLY come into play there... You want the DF to remain as high as possible.

Also, if you're gonna compete, you're gonna HAVE to get an HO alternator.

Just my two cents!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Good call Azn 13 is probably more realistic.

It is a Hifonics Brutus 2006D, which from all reviews I have read on sound domain, it does output what it claims to in wattage at each given ohm rating.

My other 2 amps are a PPI pcx2200 and a PPI pcx480.

Thanks guys for the helpful comments!

I don't want to be a a nay-sayer, but I don't think that Brutus amp puts out 2000 amps. I am not saying it isn't a good amplifier, but Hifonics amps don't always seem to put out the described power. Well atleast in my experiences. The give you a good bang for the buck though.

That's my opinion. Take it, leave it, or correct me.

yeah Car Audio Mag revieved the Colossus I think and said it does put out rated power....AT ABOVE 10% distorion. But at 1% distortionit does not put out rated power
