Upgrading stereo, need some advice

Agree with that.  Amp the rears no matter how little respect you give them.  There are cheap amps available for cheap rear speakers....or better, four-channel amps that you can cheapen on the 3/4 end.

Keep this in mind:  you won't be making your own decision...when it comes to speakers...until you listen to them.  Problem is, sometimes you have to listen to them (and thus make your decision) after you buy and install them.  If you have just nowhere to go to look...

I can't remember this, but since I want to amp both front & rear 50wrms speakers, do I need to look for 100 x 4? or 50 x 2, on a 4-channel amp.

or would that be basically the same thing?

thanks. i couldn't remember.

would this be a good amp for those speakers?

here is another one I'm interested in, but would like a second opinion, as well as the first link.

I know Fosgate is a good brand name, but never experienced their equipment.

sorry for the triple post, but here is another one i'm looking at.

I heard both good and bad reviews about HiFonics, but I would like some extra opions.

Thanks again.
