The OP, Bobbi, has an 08 Impala...

And I have no rear... The only speakers behind me are 4 18's... lol

I have a pair of Tweeters for rears and 4 10s isoberic style ... lol

I think rears area good thing if done corectly. So far shitbrick I think your rears are set up fine. Who ever said that the mid should give the "impact" ( I think thats the word he used) and the sub gives the "body".... very good way to put it. You need to have the punch and sound come from the mids, and the fill or "body" from the sub. You should not be able to point at the sub when listening. Its just kind of there. Yes you will have to tune a bit after the swap, but time wont change... much. I think that some drivers acctually can give you a more natural sound than others, and some can give better dispersion, with that, time will come into play. The math is the best way to get started on your time, but from there you do need to just push and pull the distance (time) to get it right where it needs to be. Just like with an SPL build, the math will only give you ballpark, after that you build, rebuild, re-rebuild,re-re-rebuild until its just right. The other thing is, when you tune your car, don't sit there for to long. Do it for a while then walk away. Come back to it a bit later, because your ears will get fatuiged and you will start to hear things that arnt there and you will get confused. Also on the recone, do it. Back to the SQ of it... The other thing you could do is drive here and let me tune it lol. Also get a dash mat or try a towel first to see if reflections are a factor with your tweets in the pillar. Other than that, I really don't know much about SQ....

I'm relatively new to the SQ side of car audio but there has been some things I have learned.

Swapping a set of speakers will in general make a significant difference right away. However, for SQ it will of course take some tuning. Before a swap the ideal suggestion is to decide what aspects you are trying to achieve. Sometimes putting effort into relocating/building the speaker locations may be more beneficial. Skittles can chime in here with what he has done. Staging height,width or depth are each tricky. To get a center without losing your width, to get the feeling of the sound at your eyes with placements in your feet. I believe that you should be able to achieve a decent SQ set up without going to a 3-way but, it may also be an option you may want to consider.

As for the subwoofer, its relative location should not draw your ears attention. However, its presence must be known. This really comes down to tuning and frequency choices. The blend between your mid-bass and sub-bass should be seemless and compliment each other. As if the mid-bass (which should be located in your front stage) should give the initial "ear" impact and the sub to carry out the "body" impact.

With a full active 701 you have a great control on your system obviously. The rear fill sound like you have a good control of keeping it where it needs to be. From the little I hear rear fill won't solidify your front stage but, correctly adjusted will help with ambience and realism. Personally, I haven't been that bold to try using rear fill as the front stage alone is a headache. I don't know if I was any help but, its my .02

you may be fairly new to SQ, but you are a trained SQ judge, so your opinions and advice should be respected.
