Hey there, frequent reader, rare poster, but anyway...

I am in the market for some 6.5 component speakers and am having trouble deciding between diamond hex, boston sl60s, and polk mmc6500... but anywho thats beside the point. my question is, would it be possible to power just my rear alpine coaxials with headunit power and maybe get a two channel amp to power the components in front? At first, i was going to get a 4 channel, but being a SQ nut, am leaning towards just getting a two channel to effectively power the components up front. what would you guys recommend? 4 channel and power all four speakers? 2 channel and really let the components sing? other?? help is very much appreciated, i know you guys know your stuff!

thanks again guys,

Joe Milner

sorry for the double post, (can new users not edit or am i just dumb??)

As far as the component choices go, I like to listen to rock and acoustics mostly... I would like to be able to achieve the best SQ possible, don't care much at all for SPL. I understand theres no better tool than your own ears when choosing speakers but i was just wondering which of the three i've listed you guys would recommend? I know theres hundreds of redundant threads regarding component suggestions, but i was just wondering.

Thanks again for you time

The speakers you posted are far apart, you're gonna need to tell us what your preferences are with regards to mellow vs. bright and the sound you're looking for from the midrange driver. Also, what's your budget for your components?

Grab a 2-channel, run the rears off your head unit. No need for a 4-channel

are they? well i kinda like a mellower tweeter, something that won't fatigue the ears with overpowering highs... my budget is around 300... and i was pretty set on an alpine amp since i have one powering my sub and really like how cool it stays. I was looking at the vpower line but i don't think they come in 2 channel. Would i see a considerable drop in sound quality if i bridged the 4 channel into 2? also, i have an alpine headunit that pushes 18x4 watts. i don't think its possible to run 36x2 to the 6x9s. That'd probably fry my HU right??

alright, well im pretty well set on the diamond audios... i listened to them today and really liked the way they sounded and the fact that they handle so much power caught my eye. Anyway, i was wondering how much power you would recommend feeding to these? i'm not sure if i should get this amp...

it'd be nice to save the fourty bucks and get the 300, but what would you guys recommend? do you think 150x2 would be enough?? from what i understand, hexs are rather power hungry. thanks guys

also, this amp has separate crossovers for front and rear channels. Would i have to make sure to set them both the same if i do bridge it? jeez, everyime i post a message, i think of a different question... why can't i edit??

*EDIT*... sorry for the millions of separate posts! just figured it out
