vbrad511 Posted November 12, 2010 Report Share Posted November 12, 2010 I've got a Pioneer head unit that advertises 50w x 4. I've got a pair of boxes with 6.5's and tweets in each. Can I trust this pioneer to fire these? Efficiently? Link to comment Share on other sites More sharing options...
AutoBodyGod Posted November 12, 2010 Report Share Posted November 12, 2010 No... Manufactures should be hung for falsely advertising. I would bet your Pioneer probably puts out 20x4. Link to comment Share on other sites More sharing options...
starquestG54B Posted November 12, 2010 Report Share Posted November 12, 2010 it will power them. i have done this many times and it sounds good. it will work dont worry. a amp is only needed if you plan on running a subwoofer Link to comment Share on other sites More sharing options...
Burton Posted November 12, 2010 Report Share Posted November 12, 2010 (edited) I wouldn't. A typical rule of thumb I've always followed is that any truck box or component speaker set that has an inline crossover needs to be amped. Most of those style of speakers usually like to have at least 100W of "true" power. 50W per channel deck power is realistically about 20-25W at best. It might do it, but not efficently. You can damage speakers by underpowering them just as easy as you can do it by overpowering them. Edited November 12, 2010 by Burton Link to comment Share on other sites More sharing options...
speed racer Posted November 14, 2010 Report Share Posted November 14, 2010 head unit power ok if ya just want sound but if want good sound and volume.Even a small amp of 30watts per channel better than a deck w 50x4.esp if gonna have a sub of any kind.you'll just keep blowing up those trying to keep up.

When doing that, pay attention to the nominal (or RMS) wattage and the peak wattage. I believe most head units advertise in peak power, meaning the most power they will supply. All this being said, for the best efficiency, I agree with the other guys that you'll want to go with a seperate amp. Jake Link to comment Share on other sites More sharing options...
