whats the replacment speaker sizes i need for from and back doors of a 52 scooby?

 

Sure its something like 4inch. You swopping them cos they are broke, or u doing a upgrade?.

If an upgrade, you really are wasting your time and money, becasue they are way too small to hear any real difference, save your cash for the fronts!.

 

im upgrading been told 6 inch front components

 

Fronts are 5.25, you can fit 6.5 though.

Rears are 4, as above I wouldn't bother with the rears. Spend the money on better fronts.

If you fit components they are much better amped. If running from the head unit get coaxials.

And sound deadening really helps!

 

the fronts will be amped eventually and what are coxials?

 

They don't have separate crossovers like components, they do mids and highs from the single speaker. They are therefore easier to install and require less power (crossovers use up a lot).

Components will generally sound better as the tweeter can be mounted in a better location - high frequencies are more 'directional' and don't work well in a footwell. I guess the main driver would interfere a bit with the tweeter mounted in it coax style as well.

Components are a much better option if you are amping them, but need to be installed properly to get the best out of them.

 

I should have added - components require more power (as above) and even the best headunits can't provide much. Outputs advertised are peak, so 4x50w actually means about 4x15w in real terms. Most components will need >20-40w minimum. By turning your headunit up to compensate for the lack of power, you can damage the speakers.

HTH.
