It's really going to depend on what car it's fitted into, and how
well
(ie. whether speaker positions are well damped, etc), but you should
get pretty good results. The only thing you may find is that, because
you're using relatively small 13cm drivers, they may not produce
enough output to compete with the sub. That's probably going to be
limited more by the actual speaker size than the head unit's output
though.


It's just a small car I have not got it yet but am going to by the end
of Feburary. Probably a new style corsa. But I do not know what
components would fit in a corsa If the 16.5cm ones fit I would get
them for same price.
Would the Alpine SPR-176A 16.5cm components be a better option then as
they are bigger, or should I get an additional amp to power the 13cm
components.
I've read 6x9's are not a good idea as it makes all the sound come
from behind you, and the 6x9's try to compete with the sub and then
makes the bass sound worse. This is why I decided on more expensive
components but if these wont be able to compete with the sub what do
you suggest?
