    Which size is better for rear speakers with no amp? 4" or 5 1/4"

    I'm getting a new head unit but will not have the money for front components and an amp for awhile, if not ever. However I do want to replace the rears with some <$100 coax speakers to help clean it up a little.

    I will stay with something that recommends no more then 30 to 45 RMS and my head unit will probably run 22 to 23 RMS.

    Is it even worth getting new speakers? Should I go 4" or 5 1/4" speakers?

    Thanks

    yes, get the new speakers. I dont know if you've seen what the factory speakers look like, but they are cheesy!!! Anyway, with proper modification, 5 1/4 should fit just fine. Any well known brand with a rating of 40-60 watts should work out fine. However, I think it is ten times more important to have the best front speakers possible. Even to the point of leaving the rear one's stock.

    You can get cheap decent speakers for less than $100 a pair... like these :-

    Alpine SPS170

    Alpine SPS 100A

    These would sound pretty good with your new head, obviously the more you spend the better sound gets, (until you hit the law of dimininshing returns)

    godd choices ludecrous. However, I have to stay with my initial observation that the FRONT speakers are the MOST important.

    Thanks I will for sure do the fronts first. I know the stock speakers are crap I just don't want to put anything new into the fronts that I can't power correctly.

    I'll probably hold out for some infinity components and an amp.

    Thanks, for your help

    Yeah front speakers are the most important, in my opinion, too. I can hardly hear the rear speakers with my sub-woofers blaring.

    are you sure that 5 1/4" speakers will fit? I know that they will sound better than 4" Speakers no doubt. Usually the bigger the speaker, the higher the sensativity rating is, the more sound you get out of them for the same amount of power. You also have stronger midbass.

    **edit**
    It turns out that even though crutchfield says 4" front and back, infinity claims 5.25" front and back. I plan on going with infinity kappa components up front (factory location) and infinity kappa rears.
