I just bought an old motorhome and am planning on installing 4 Pioneer 330 watt 6x9s and am unsure what kind of amp I need. I have a very cheap deck, but figure that won't matter if I get the right amp that can power all four speakers. Please if you have any help for melet me know.

Thanks,
Christopher

you'll need a 600 watt 4 channel amp so there would be 150 watts per speaker which is enough for 6x9's
