View Full Version : Should this blow out my right rear speaker?

11-07-2008, 06:58 PM
I just got a a new head unit and 4 speakers installed into my Honda Accord exactly a week ago.

The faceplate is a Alpine CDA-9886:

The Door speakers are Alpine SPS-600:

The two rear speakers below the window are Rockford Fosgate Punch P1694C:

I turned off the HPF and have the bass at about +3 and the treble to about -2 to balance it out. I keep my volume at about 18 and maybe 20 sometimes if I wanna hear the bass a bit more with some rap or something similar. As of lately though my right rear speaker just doesn't produce any sound. When it does, its all crackley and sounds horrible. So I took it to where I got it installed and they said HPF should be on and it was too much bass for the speaker to handle. I decided to go to another car audio place, and they said that couldn't be it at all. They said there is not enough power to cause that. So basically, who do I believe, or what should I do? This setup wasn't cheap and it shouldn't be going out this soon.

Any thoughts and ideas are highly appreciated!

you need a hpf, they are not meant to play those frequencies. only 80+

you need a subwoofer, ill sell you one

So is it bad to have HPF turned on with only these speakers in my car? I want to feel at least some bass, that’s the whole reason I got the RF. The salesman said that RF would give me deeper low’s (bass) over the Alpines. The only reason I have Alpine in the door, is because I guess the RF were too big and wouldn’t fit in the panel.

you're not going to get low bass out of those speakers, they're simply not made that way. if you want that low bass you have to get a sub, even a small 10" sub can produce that sound.

now you certainly can blow speakers with less then the rated power. this happens if you push your amp past it's clipping point. when you start clipping your signal, you're pushing much much more power to your speakers. now it generally sounds like hot garbage when it goes through your speakers so people tend to not clip for long, but if you were trying to squeeze out extra bass then it's possibly you let it clip for too long, pushed too much power, overheated and thus blew the voice coil.

but you should be running your high pass filter. right now all the frequencies are going to that speaker and it's trying to reproduce those. but it's not made for that, especially at high volumes.
