too much power, or you may be pushing the amp too hard...what are the speakers and what amp?

maybe your speakers are rated at 49 watts rms and that extra watt is causin some problems

ok i found out they only distort when there is bass playing so like if there is a section on a song with no bass then they dont distort. as soon as the bass comes on again they distort any help?

Well everyone is going to make fun of you, so I am going to actually try and help you with this issue, because not everyone is a self-proclaimed car audio genius. All the other people on the board that like to make fun of everyone else and act like jagoffs knew nothing until they got to this site, now that they have read a lot of "bona fide" information posted by people they don't even know, they consider themselves experts and make fun of anyone who asks a question that seems noobish...Anywho....

First thing, I would check the High Pass Filter on your amplifier, make sure it is in the "HP" setting, then, while listening to the music that makes them distort the worst, gradually adjust the crossover higher until the distortion stops. If you have to go above 100hz on the crossover, then you need to turn the bass boost down on the head unit.

Many will tell you that you really shouldn't use the HU to "boost" the signal of any frequencies. Only to make "cuts" i.e., turn down certain frequencies. If you don't have enough bass, add a speaker designed to produce bass--a good subwoofer. Maybe you already have one, we don't know, but don't rely on door speakers to provide you with any real bass below 80hz for average speakers...If you do have a sub and still feel the need to crank the bass up to +3, maybe you need another sub. Keep the low bass out of your door speaks, and let the subs handle it, that is what they are made for.

Well, every system is different. Some subs play well up to 50hz, some play well up to 100hz. Are you sealed or ported?

Basically you are confined to setting your High Pass filter for your speakers to the lowest level at which they can still play loud without distorting. If it's 70hz, great. If it's 110hz, not so good, but if that's all they can handle, that's what you have to live with, or get better speakers. Turn the bass down on the HU first. GET THE BASS OUT OF THE SPEAKERS! Then adjust your Xover for the speakers. If you need more bass, boost the bass on the sub channels of the amp if you have too. Doing it from the HU is sending it to the speakers AND the sub. If you have a sub output with variable output, keep it up high as long as subs are not distorting. Run the Low Pass Xover for the subs a little lower than what your speakers are set at. If the speakers end up at 90 hz, run the subs at 75hz or so. A little underlap is okay since the crossover will let some bleed thru still to fill that gap. But get your speakers set first, then adjust the subs to match...

give us the full detail of your system so we can figure out whats needed...we have the same hu...also dont expect alot of bass coming out of your door speakers thats why u have subs they only play certain frequencies cranking them too loud will only cause damage to the speakers you have to level match everything:)

ok yeah thanks guys im going to wait until the morning to change some settings.


my complete setup:
HU: alpine iva-w200
amp: rockford fosgate p400-4
speakers: rockford fosgate punch not sure which exact model
subs: rockford fosgate 12" p3s 2ohm
sealed enclosure
i have one mid and 1 tweeter in each door
and i have one tweeter in each pillar by my windshield

i think i will be able to fix it after dftnz7's advice

thanks to all!

correct answer

my bet is a HU.
based off the only info I had

lol....50x4:laugh:

haha nah dude i dont think that is the problem lol

NOT NECESSARILY SO


First thing, I would check the High Pass Filter on your amplifier, make sure it is in the "HP" setting, then, while listening to the music that makes them distort the worst, gradually adjust the crossover higher until the distortion stops. If you have bass boost on the HU or amp, turn it to 0.

corrected.

finally we get a full set up! If the HU has HP on the outputs that would help too, there might be adjustable slopes also. I would use the steepest slope possible on the front speakers.
