I have a Pioneer p9300 hu, 2 4x6cfp infinity kappa and 2 6x9 kappas(silver color 693.3i).

Will an rms 100x4 4ohm amp be alright for this set up?

Thanks

It'll be too much for those speakers IMO. You don't power regular speakers at 100 per rms, it just isn't the way to go. They are designed for ~50 or so, I nice 50x4 would do you fine.

Would it be wise to power a speaker,say with 75 rms, at 75w?

Hope this question makes sense.

Thanks again

power them at what they are rated at.

I have posted this several times.... Amps are rated at full gain....So if you are not (I hope your not) running your amp at full gain you will never receive that rated power.... Just remember the less you turn your gain up the less distorted your speakers will sound. That equals clean tunes. The amp I have running my SPR-174A's is a MRP-F200 rated at 40w X 4 12V @ 4ohms RMS but 100w X 2 12V @ 4ohms. I bridged the amp out at 100w X 2 and have my gain all the way turned down and the music that plays out of the speakers are very pleasing. The amp never runs hot either. No distortion at full volume at all. That is my two cents. I hope it helps you out. IMO wattage doesn't blow speakers, freq does unless you have a monstrous amp running stock speakers.
thanks,

the //////\LPINE SPR-174A are rated at 40w rms and 160w peak.

This is funny. I've always read, and this is from reputable sources, not just some clowns who say they know audio, that you should buy all the power you can afford. The amount of power in your system affects more than just the peak output of your system. Several years ago, Carver conducted an experiment in which they tried to reproduce as accurately as possible the sound of a pin drop. They stopped at several thousand watts and though the sound reproduction improved with every application of added power, they never EXACTLY reproduced the sound. This they say, proved that power is essential to good sound reproduction and not just peak power. Just my .02.

Your safest bet is to look at the speakers' recommended power ratings. As long as you stay within those guidelines you should be fine. You run into problems when you pump too much wattage to those speakers and they blow. I assume you already have the speakers and are deciding on how many watts. If you thought the speakers you had didn't handle enough power, you could get ones that could handle more power. Then in turn the new speakers would be A) loud enough and B) handle the increased wattage. My Eclipse amp has 85x4, and dont really even know where the gains are set, because of where the amp rack is mounted, blocking the gains. Needless to say the Focal components scream. I am left many times getting out of my car with ears ringing. BTW... I listen to mainly hard rock (Nickelback, Metallica, Creed, Pantera, & Korn).

by the way folks, Kappas are rated at 90 rms and 270w max..But what kind of impendance do they have? If you run them at 4ohm you gona be fine, if 2ohm it maybe a bit too much..What kind of amp is that?

Thanks guys for ALL of your inputs and advice, they are very much appriciated.

For the speakers I have decided to give this a try.

PPI Precision Power PCX-480 / 4-Ch Amp.

It has 80w x 4 @ 4 ohms, within the rms 100w and 110w speakers

What do you guys think,

best regards,
Mike

Whoops

I made a typo, I have the infinity kappa perfect 6.1 not the kappa 4x6's.<------ my old ones

Perfects are rated at rms 100w and max 400w.

The kappa 693.5i 6x9 are rated at rms 110w and max 330w

(www.infinitysystems.com for more info)

That should be fine. But like AZN2DMAX indicated clean power is not the most common cause of voice coil meltdown. I would feel safe using 250X4 RMS if I could afford that much clean power. But if I could afford that much clean power, I wouldn't have infinity's.

Thank you FREEDOG....
