The mounting depth is quoted as 69.5mm. Anyone know if these wll fit in a coop front doors and anyone know if they are any good? Probabley be choosng a small alpine amp with alpiny head unit too.

What you folks think??
cheers mike

should go in easy mate, alpine head units are [sound wise] as good as you will get the amps are clean and punchy well detailed [value for money, and bullet proof], shop around a bit on the speekers they are a decent set up but you mite get better for the same money/or save on those
