Clarion or Konaki?

Well, if you're going to get CVXs, you'll need more power. 700w is only enough for one, really. I said CVRs because they'll do a good job of making the most of the power you've got now.

I'm running both of mine on only 638 watts RMS. That's what my amp tested at @ 2 ohms. They behave more like SQ subs with that little of power going into them. I'm able to accomplish walking bass lines with clarity!!! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

EDIT: I'm sure my 720PRS comps have a little to do with that too though...

measure how much im pushing that is.

No, thats a total of 700w. 350 per sub.

cvr's are great budget subs, and can get very loud when ported. I had 3 10's in my mustang with 1200 watts rms to them sealed and it still got very loud

I used to run 2 12" CVRs. They got decently loud off of 600 watts, but they didn't play very cleanly. That's why I upgraded to the CVXs and kept the same power.

ok. i thought it said x2 channel. my bad.

 

[AudioEnthusiast 10+ year member]

ok. Thanks for the insight. Im very picky when it comes to audio. especially about the clarity.

and im running 2 jbl gtos and when i turn the gain, lpf and bass boost up they look as though they might bust. ha.

how much power am i really running? any ideas? what do you use to measure how much its putting out?

Well, assuming you've got a 2 ohm load, use a multimeter and a 50 Hz test tone at 0 dB to measure the voltage your amp puts out, square it, then divide by 2. This will be the power your amp is putting out at 2 ohms. This is by no means clean power. You would have to use an o-scope to see if it's clean or clipped.

You should be getting approximately 37.4 volts if your amp is actually capable of 700 watts @ 2 ohms.

 

[AudioEnthusiast 10+ year member]

sorry for not specifying but there 4 ohm.

 

[AudioEnthusiast 10+ year member]

Thanks. do you do the same thing for a 4 ohm? and what if i dont have a 50hz frequency. Can i use a song with a decently constant note?

 

[ejschultz 10+ year member]

I am assuming you're running the amp at 2 ohms with 2 4 ohm subs? Am I correct in this assumption? Otherwise, you will divide by 4 for a 4 ohm load. The general equation for figuring out the voltage you should be getting is V=sqrt(PZ) where P is the power and Z is the impedance of the load per channel.

Oh, and for the test tone, Audacity is a great, free tool. You can make a 50 Hz test tone at 0 or -3 dB pretty easily in it.
