I have a 2002 astra which has a mid range and tweeter in all four of the
doors. Next year I'm planning to buy an MP3 player the equivalent to the
Alpine 9815 (only reason I have not bought one of these already is because I
heard there is still a delay beween mp3 tracks, hoping this will not be the
case in next years model). Anyway I don't want to modify the car too much so
was wondering how easy it would be to keep the original speakers but cut out
the low frequencys to them and add a sub or 2. I'm thinking if the original
speakers are only fed with the frequencies they are designed for they will
probably sound ok. Anybody got any commets on this, is it a good idea or
not?
