i have a 99 honda civic and everywhere i look it says that it uses 6.5" speakers. so i bought a pair of eD speakers but they were to big. the factory ones are about 6". i was just wondering if all 6.5" speakers are the same size and what is the mounting diameter i keep seeing... i was looking at some 6.5" diamond audio speakers and i had the mounting diameter as 5 and some odd inches...there is no way the 6.5" eD speakers are gonna fit...so should i just get 6" speakers??? if so they are kinda hard to find...especially at the 100 watts rms range..any suggestions???
