System:
HeadUnit:Alpine CDA 9851
Front Speakers: Eclipse SP8954 5-1/4" 2 Way Point Source
Rear Speakers: Eclipse SP8974 5X7" 2 Way Point Source
Wiring: Stinger 1/0 from front to Stinger Distro block, the to two 4 gauge wires. Ground is abprx 10" Stinger 1/0 to distro block where it splits up into two 4 guage traveling aprx 4" to each amp. 2 sets of Street Wires RCA's. One set for subwoofers, hooked up accordingly to hu, and the other set for all 4 speakers (Hooked up to front speakers out put on hu(3 sets of pre outs)). 16.5' long rca's. 2 Street Wires RCA Y-splitters
Amps:

Profile CA1200 (450x2 RMS @ 2 ohms), and Profile CA1000 (75x4 RMS @ 4 ohms) (These models are now lcalled like CB or CE or something i duno but still the same as CA) (I NEED NEW AMPS! BUT HELL THEY WERE NEW AND FREE!) :)

The Problem: Well i was messing around today with amp settings etc because i noticed the fronts not nearly as loud as the rears. So i made sure my left and rights were hooked up right via rca's etc and sound tests. All that was go, left sound plays left speakers only visa versa. I then checked to make sure everything was wired correctly and for the most part i'm 100% sure it is. I then checked my hu settings. All are at like basicaly 0, bass is at 3 @ 80 hz, Treble is at 3 at 1.2 khz, Subwoofer is at 12 (0-15). Balance, and fader are @ 0. And defeate, and bbe are off. My gains on both speakers is 75% of the way up and each are set equal with reares down just a tad bit. When i turn it down more they sound crummy and loose alot of their potential. Also same with the subs, that gain is up @ 75% with bass bost @ 3 db, crossover @ 80 hz and Filter on low pass.
i think the gains are up too high, but they were set according to how they should be set, i followed instructions, lol and double checked w/ crutchfield. Turned volume up 75% of the way and messed w/ gain till distorts about to happen. Then down a tad from there.
Also when i play a 1 hz, to 22hz even though i can't hear it (don't no of many people that can :) ) the speakers, only noticed it on the rear right one, seem to hiss and make sort of funny noise if i turn it up to about 19 (0-35 volume). Sort of like a sine wave sweep noise up and down rather high pitched.

Any idea at what these problems migt be caused from?
INeed more info? Just ask!
Thanks guys i have a few ideas as to the problem but wil let the more exp. take a shot :) !

I'd try swapping the RCA inputs for the front and rears (put the front's in the rears and vice versa). If that doesn't do anything, try swapping the speaker outputs. If it is neither of those, then there is probably nothing you can do with it being the speakers themselves.

Tried that, tried both, i swapped rca's nothing, tried outputs, nohing.
So you think its my front speakers?

Well, it may just be the nature of the speakers. Are they a lot quieter than they used to be? or just too quiet?

i never noticed them being any louder than they ever were. The are just too quiet i guess you could say. I duno they sound great and everythig still.

Think maybe my amps have lot to do with it?

They could be partly to blame, but they would have to be putting out less than they state for it to really matter. If you have anyone close to you that you can use their amp to test, try to do that and see if the speakers behave differently. (don't take the amp out and all, just run a long speaker wire from the other car to the *unhooked* leads from your amp.
