yea you will need an adaptor - the adaptor can allow for 13cm or 17cm speakers in the front... I'm gonna do the back ones put some 13cm's in there Alpine Type R woohoo!

i heard if was 6.5(17cm)

so would a set of 13 or 17cm £30 speakers, give me a noticeable improvement. and don't say nope dont get them get a door build wiv £200 worth of speakers. cos im on a budget. cheers. also do i need an adaptor to fit new speakers or wot? and wot is the largest that will fit in a standard door

of course it will, aftermarket speakers are much better, you get what you pay for ;)

door pods

6 1/2 inch speakers at full pelt :D

yeah i just fitted a beasuty of a headunit and i feel i cant enjoy the full power of it using standard speakers,so it will definately improve it then

yes, the standard ones have cardboard cones and are crap, even cheap ones would make a difference

DEPEND ON WHAT SPEAKERS THEY ARE BUT M,OST DEFINET YES EXPECIALLY IF THERE ALPINE OR ROCKFORD.
BUT DEF GET COMPONENTS MUCH BETTER

would changing the standard front speakers on my corsa b sport, make a noticable diff??
