    horrible distorting...

    Installed my amp yesterday to power my rear speakers, its a 40x2 rms to 50 rms speakers which were formerly powered by the headunit. It sounds nice with no bass, but when any low frequency gets played it distorts horribly, worse than before the amp. I've messed with the gains, and some headunit settings, what else should i check? bad connection somewhere? I expected lower distortion...not more. Please help.

    What speakers and amp do you have? Sounds like you just have lower quality equipment. Try turning the bass all the way down and see if it still distorts. If it stops, turn it slowly and when hear some distortion, go back a few notches and leave it alone.

    most speakers are not designed to play the lower freq. spectrum....most likly need to have a high pass filter set to block the low freq's if possible......

    Well, I'm using the sonys that are in my sig and the pioneer amp that is in my sig, they aren't great but they suffice untill June 1st But anyways, I know that those 6x9s aren't going to get sub-quality bass, but when I was powering them with my headunit, the bass was alot better than what it is now.

    The problem is that they're 6x9's....the oval design is conducive to distorting, especially when you push them to their limits. Your HU wasn't providing quite enough to power to make the distortion incredibly noticeable, but when you made the jump to 40 watts, that distortion becomes much louder and much worse. You should set an HPF on the speakers at around 80 or so, set your gains properly, and dont turn up the bass on your HU settings. That's about all you can do...but there's only so much you can do with 6x9's

    hm...never thought of it like that gauntlet. The problem with that then would be i would be getting NO bass whatsoever, considering i only have 3.5"s in the front. Maybe i should just hook them back up to the headunit and wait till i get a sub.

    Just turn the gains down on the amp. Your amp can send cleaner power to the speakers than your head unit can.

    i've tried that, the only thing it seems to do is lower the volume of the speakers the amp is powering, it still distorts.

    i know they were the first thing i ever bought to upgrade my sound in the car, unfortunately it was also before i knew anything. i would upgrade, but im saving for a sub instead and after that i may take them out. or maybe buy some circular speakers and put em in the baskets.

    All 6x9 speakers don't distort. You can still have 6x9s if you want.. they can generally get louder and deeper than 6.5"s in the same price range. If you like the sound from a 6x9 don't not get them because your cheaper quality ones are prone to distort when you send em 40 watts.

    No. All 6x9 speakers will distort when they reach full excursion.

    subs are a bit of a diff. story.....but yes i velieve the hexagonal subs would have a tad bit more of a problem recreating the freq's than a round sub.....

    Almost all speakers will.. What I was saying is that if he likes the sound from a 6x9 he should not be repelled from them because his lower quality ones distort at his current listening levels. He will not have that problem if he has a better speaker.
