Do I need a crossover?

[temuchan 10+ year member]

I just wired my door speakers ( two 5 1/4 and two tweeters ) up to a 50x4 RMS amp. This amp lets you highpass two of the channels and lowpass the other two, so I put the tweeters on the highpass channels.

Now my 5 1/4 speakers rattle with certain songs, especially ones with lots of bass. Do you think I should get a crossover ( I'd be open to passive or active ) to stop the speakers from playing so low? Or do you think I am giving them too much power? I have the gains set at about 3/4.

What is the highpass freq that you have on the tweets?

 

[temuchan 10+ year member]

the highpass is at 80, its just an on or off switch.

With the tweeters only wired on that highpass, they're toast already. That highpass was meant for the mids. Chances are good that the mids are in bad shape if not already blown.

there are a few tweets can be crossed as low as 80hz. I call them mids.

the values you set them will vary based on the brand. If you have a response sheet you can set for the ideal. Otherwise, do it by ear and follow the guidelines below.

the highpass should be set for well over 2k

mids should not play anything under 70-80 and play no higher then 2k (low-pass at the same value as your highpass).
