Quick amp question

[09civic 5,000+ posts]

Alright im only 16 so dont hate on me too much im just tryin to learn...so lets say i have 2 subs that are dual 4... If i wired them both to 2 ohms and i want at least 600 watts out of each sub, what amp should i get? Not brand wise but just an amp with enough to push that. I know what to do if im just workin with one sub but whwn it comes to two... Im lost lol

You cant wire two dual 4ohm subs to 2 ohm. Only 1 or 4 ohm

if you wired each sub to 2 ohm, and paralleled them to a 1 ohm total, just find something in the 2k-3k power range @ 1 ohm, add one or two extra batteries, 0/1g wire at the least, bla bla bla...

There's plenty of amps out there that are going to put out 600 RMS @ 4 ohms. That's what you're going to want. You'd have to do some electrical upgrades to wire the subs down to 1 ohm, not to mention, you wouldn't need to do that as it's usually for higher powered systems. The Alpine MRP-M1000 is a decently built amp that will give you 600 RMS @ 4 ohms.

so i can wire them both to 2 ohms making a total of 4 ohms so i have to look at what the amp does at 4 ohms?

Essentially. With a pair of dual 4 ohm subs, you can either keep the impedance at 4 ohms by a mixture of series parallel wiring, go down to 1 ohm by all parallel wiring, or go up to 16 ohms with all series wiring. For the amount of power you require, wiring to 4 ohms is your best bet. There are plenty of wiring diagrams online available for free if you don't know exactly how to do it.

alright thank you.

 

[ejschultz 10+ year member]

Yup, no problem.

And for reference...

Pretty much how to wire anything.

So if i wire to 4ohms...imma need a pretty beast amp ha

 

[ejschultz 10+ year member]

Not necessarily. Most amps that'll do 1000 RMS @ 2 ohms will do about 600 @ 4 ohms. I don't think you'll necessarily need something too beastly for that.

alright. one more question. lets say i had one sa 15 d4 and this amp: NEW POWERBASS XA-1500D 1500w RMS MONO AMPLIFIER+AMP KIT - eBay (item 350400304338 end time Jan-30-11 18:09:58 PST). (not saying im buying it) and wired to 2 ohms...it does 1000 at 2...would that be a little too much to push to that sub for daily use?

That sub takes what? About 600 RMS IIRC? I'd say if you don't turn the gain too high, you'll be fine. Someone, I'm sure, will correct me if I'm wrong on what that sub takes. I'm not looking it up because I'm posting this from my iPod. Rule of thumb though, it doesn't hurt to have too much power on tap, as long as you don't abuse it. In otherwords, regardless of equipment, you can use an amp that supplies more power than the driver will handle as long as the gain is set accordingly.

yes it it 600 rms. everyone says they can take double but i dont wanna beat the **** outta it

that same amp will work with 2, 4dvc subs as well. wireing them up @ 1ohm. that amp is stable @ 1ohm. so 1500rms to both subs will give you 750each.
