i have 2 6.5 momo's (MMC 6500) in my front doors. rms for them is 240. they might have 70 going to them continuously. why whenever i start getting loud do they get distorted? is it my door panels rattling? something with my head unit? any possible solutions would be great. they should not sound that bad for the quality speakers they are.

Well rms for those is actually 80 watt and 180 peak

What amp are you powering them with does it have a x-over or banpass option so you can tweak them a bit or have you tried with you Hu?

Also how r they installed and is the door deadened?

80....i was told it was 240, guess i should have checked the box :graduate: the only tweaking i have done is to mess with the eq on my head. the only way it gets better is when i take out the bass most of the way. im gonna go out now and play wih the amp and see what happens though.

Set a high pass filter to around 80hz on your HU. Your amp should have one if your HU doesn't..

Also make sure that the amp isn't clipping.

Yes, follow the advice of others and check your gain settings on the amp and make sure you are running a HP filter of around 80Hz to those mids.

swapped over to the hpf and set it at around 80hz and they still sound like ****. theres no way that my amp could be clipping bc its 50x4 and its wired with a 4ga. stinger kit. it has to be the install. there is a lot of rattle and extra noise that shouldnt be there so im going to take it back and get those guys to fix it. not really confident in their work since it sounds this bad right now. is there anything else i might have overlooked?

yeah i went and checked it out and saw the actual rms and max but that just shows for sure that there is no way that i could have blown them. and they arent clipping so it has to be the way that they are mounted into my doors.

dont think that they put anything to deaden them in my doors. when i find out for sure what the problem is im going to state their name and leave a reviem so no one in my area goes there to get work done

Well did you ask them to put deadener in your doors, or just to install the speakers?

i didnt tell them to deaden the dorrs but i did tell them to install my stuff and make it sound good. if you are working at a car audio place the biggest source of advertisement you have is your reputation so there is no reason that he should have let me leave with my speakers rattling and sounding like s**t. if the problem was there him as the specialist should let me know that i need something to deaden the sound, especilly when he knows that i am new to this. the right answer is not to turn the gain on my amp all the way down and try to cover it up. I dont know that he was trying to cover it up so dont quote me but it seems pretty shady at this point.

i really think that he wasnt trying to put a lot of effort into the install and he was getting tirede bc it was the last one he did that day and didnt finish until like 615

This doesn't mean your amp isn't clipping. Recheck your gains, sounds like thats your problem. You might also be clipping your head unit. I myself would check gains, high pass filters, and connections before going into deadening, clay around the speaker, and MDF rings. Here is the gain setting tutorial, I highly suggest reading it: http://www.caraudio.com/forum/showthread.php?t=63933 Good luck.
