Understanding amp vocabulary..

Well I'm now in the market for a 4 channel amp to drive my 4 pioneer speakers. My pioneers are 4 channel, 220 watt max:
http://www.bestbuy.com/site/olspage....6&type=product

I just had a few questions, so I can pick out the right amp for these speakers. First, what is all this 2/3/4 channel mess with the speakers?

Next, can someone explain the following to me (it's from the Kenwood amp which Best Buy sells for $199):

640W peak output @ 2 ohms, bridged
180W RMS (continuous) x 2 @ 2 ohms, bridged, 1kHz, 0.8% THD
90W RMS (continuous) x 4 @ 2 ohms, 1kHz, 0.8% THD
60W RMS (continuous) x 4 @ 4 ohms, 1kHz, 0.8% THD
Does this mean.. I would get 90 watts per speaker if I split it between 4 speakers? I'm so confused.

If someone wants to recommend a good amp for my speakers, please feel free.

Thanks.
Dan

What is the rms rating of your pioneer speakers? It probably says on the back of the speaker. Use the rms (continuous) rating, not the max rating. More than likely your speakers are 4 ohm speakers so if you were to use that kenwood amp from BB, you would get 60 x 4 @ 4 ohms meaning that each speaker (4 of them) would receive 60 watts rms. If you were to bridge the amp (making it into a 2 channel amp), you'll get more power (maybe too much) but you can now only run 2 speakers. It all depends on your speaker's rms rating. If I explained something wrong, step in and help me out. Hope that helps.

oh and you said that your speakers are 220 watts max, it would probably be 110 rms. Find an amp that will push up to 110 x 4 @ 4 ohms rms but you should be fine with a good 50-75 rms @ 4 ohms pushing clean power. Don't go for pyle, pyramid, rockwood, and other crap.

That helps, thanks a lot. The speakers are actually only 50 watts RMS. So I should be fine with that Kenwood..

Does anyone know the RMS rating for the stock bose speakers? I just don't want to feel like I got worse speakers than my stock..

Right now I'm a bit discouraged with my speakers, especially since the Bass punches so nicely with my dual 12" rockford's, yet my music isn't all too loud. Will an amp like that Kenwood show a good difference?

Thanks,
Dan

Soundstream Van Gogh 320.4

^^^ These are better than the kenwood amp for $200 from BB if you don't mind buying ebay.

A good amp will definately make the speakers sing louder and clearer. I have no experience with your pioneer speakers or any pioneer speaker in general so I can't tell you how they will sound.

Im pretty sure you can't use bose speakers because they run at a different ohm rating or something like that.
