Should I run 4 or 8 ohm mids?

[QUOTE="keep_hope_alive, post: 7831436, member: 576029"] it's not active if the 6.5's and 8's are on the same channel. and it is not advisable to give all 3 the same signal. having three speakers playing the same signal - yet each a different distance from your head will sound weird and poor. the effect is called comb filtering - a form of phase interference. you want to bandpass the 8" to handle midbass only. then let the 6.5's handle midrange - of which you only want 1 mid per side. if your question is if you should run two channels of the sundown at 1.33 ohms or 2.66 ohms, i vote the latter to make the load easier on the amp. later, when you have enough amp channels to do what you ultimately want, having all 4 ohm drivers is fine. but the real issue is that what you are planning to do is flawed. you're welcome to try and find out for yourself. maybe you'll like it. hell, people like Bose. running tweets active isn't gaining much. you don't need to T/A tweeters. you just want level control and crossover flexibility. you run tweets active when you have spare amps channels to play with. i would re-work your plan. run the tweeters off a passive crossover on the same channels as one 4 ohm 6.5" dedicated for midrange. then run a 8" midbass off the other channels, bandpass. this is a tried method that works well. when you have 6 amp channels, then run the various speakers individually. lastly, you don't want mids and midbass sharing the same airspace. the midbass will pressurize the mid (out of phase) and distort it. more speakers mounted on a door panel looks neat, but sounds quite poor. you want one driver producing midrange per side. you can double up on midbass drivers since the wavelengths are long enough that phase interference isn't as much of an issue when they are side-by-side. my buck-o-five [/QUOTE]
