Wire crescendo pwx to 2ohms?

[j4tk]

I am planning to get a new amplifier for my crescendo pwxs. Was going to get a ppi900.4 and thinking about running them at 2 ohms for the 150rms @ 12v. Is this sound okay? Had them running on a hifonics 1200.4, but it blew out on me.

OK, I had to look at your profile to fully understand your question. Looks like you have 4 of the 4-ohm PWX 6.5's and you want to use the ppi900/4 as a two-channel amp and run the PWX's in parallel so each channel sees 2-ohms. Correct?

The most power *per speaker* would be to run each of the four 4-ohm speakers separately on each of the 4 channels. You will get 100wRMS *per speaker* or 400W rms total.

If you run the PWXs in parallel for 2-ohms and only use 2-channels of the PPI then you will be getting 75w *per speaker* or 300 W total.

You cannot run the PPI bridged because it is only rated for a 4-ohm load when bridged.

would there be another amp you would recommend that puts out matched watts for the speakers?

There are a lot of choices for the same price range as the PPI 900/4. I'm sure many here will chime in.

Can you please confirm my assumptions above - are your PWXs the 4-ohm version? And you have 4 of them - right?

Yes. Sorry. I have 4 of the 4 ohm PWXs.

Yes. Sorry. I have 4 of the 4 ohm PWXs.

I am partial to ARC Audio and JL Audio 4-channel amps but you may have to hunt around to hit your $200 price point (what is max budget?).

If you are willing to run two of the PWXs in parallel at 2-ohms, then run a good 2-channel amp, unbridged - you will have a lot more choices.

About 200$ is right. I'm still waiting for a little more cash to come in. Going to be buying some subs and fab a box. which will cost me about 350$

he can connect them pwx's in series mode

They are 4-ohm speakers. Not sure why he would want an 8-ohm load - would result in even less power.

ahh nvm! didnt read the thread right
