Separation

also could it have anything to do with me removing my rear 5.25's? should I put my rear fill back in?

No, it wouldn't be a cause. A lot of people do not have rearfill.

It sounds to me like the first step should be to upgrade the front speakers. And see my comment on sound deadening; If not done it should be. After those two steps are accomplished then start going thru the list of things I previously mentioned again.

This is, ofcourse, assuming you are interested in upgrading your stereo. If you're not, that's fine. But with those speakers (which I'm assuming are co-axials and not components) then it's going to be a bit more challenging to get everything sounding great and blending well.

That'll probably just draw even more sound to the rear. Anyway first thing I'd do is play with the crossover. Try a steeper slope as well as a lower xo frequency. When you get the best blend you can stop. Next step would be phase adjustment. If your amp or hu can't do continual phase adjustment then simply go to your amp and switch the positive and negative speaker wires. Then relisten to your setup and see if the bass sounds better or worse. Keep it whichever way it sounds better. Then do the same to your midbass. At that point my last suggestion would be simply turn the sub down. Usually the last step works 99% of the time and is usually the culprit.

I did turn the sub down. and my fronts arent amped soo yah

but thanks fr the advice

and if i remember corectly the OP didnt mention anything about having a gap just that the bass is coming from behind...two different things in my book, dont know for you all

And the issues we mentioned are the best way to fix that problem.

Time alignment is not the only way, or even the best way, to fix sub integration issues.

again, if xovers are set correctly eq-ing will help but u still cant change the fact that the sub is in your trunk not up front.. changing the phase on the midbass wont do much good in that matter...in anycase ill agree that we disagree

Crossover selection is critical to proper integration....someone might think it's right when it can be improved upon in either frequency or slope selection. Changing phase of the sub or midbass' certainly can help. Level adjustment & EQ are just as important aswell as proper sound deadening. Time alignment should be the very last thing....and isn't necessarily always needed. I never said it would never help at all.....but you place it far too high on the priority list and seem to ignore other more important factors.

im not placing it too high just from my experience changing the phase doesnt do much good in the matter of sub imaging....setting the xover correctly most definately yes, but reversing the phase on the mid bass drivers gives a certain muddyness to the sound i cant pinpoint...reversing the phase on the one on the drivers side made a difference true, reversing the tweets gives a certain depth to the stage but all of the reversed just sounds out of place for me...

i read that the OP has a 5'25(13 cm) front system, maybe thats why the lack of the lower midbass or the sub sounding way in the back, i dont know but the more i write in this thread the more i get the feeling the xovers all screwed up so maybe check that out first?

Set the LPF to the subs lower than 80Hz as that can help to make it harder to localize the sound. Mine are at 63hz and blend very nicely and sound like they're up front. But when I crank it up and they pound the back of my seat, then it "appears" to be coming from the back again.

Sounds like you have far too much substage for a couple of little coax's up front. Improving your front stage would help a lot.

Wow did this get complicated for something that should be fairly simple. Now that we have all the info I think it's pretty obvious. 5 1/4" speakers run off a head unit aren't going to be able to keep up with the sub setup. Turning the gain on the sub amp down (like you've done) will help. Changing the LPF lower (like mlstrass recommended) could help too.

Eventually you may want to consider getting another amp for the fronts and upgrading the speakers to something that has more midbass. If you can fit 6 1/2's in the doors I'd go with those. When you do the upgrade consider sound deadener for the front doors and try to seal them as well as possible. That'll make a better enclosure for the speakers.
