View Full Version : Speakers hitting factory grilles

So today I noticed that when I'm listening to a more "punchy" song like RHCP Aeroplane, my Focals hit my factory speaker grilles on my front doors (cutting the factory grilles out is not an option for my car). There's no distortion, I just noticed it when I was sitting and listening to music. I decided to put my hand on the door and I can feel it. I turned them down a little, but they still manage to touch on a song like the one I mentioned. How bad is that for the speaker?

Well, I urned them down a little more and set the crossover a little higher. I guess I can sacrifice midbass from the front doors to protect my speakers.

They didn't stop hitting the grilles until I got the crossover to 200 hz at 18 dB/oct. Definitely no more midbass.

I has a similar problem when I had a 1/2 in wood adapter, but don't hit anymore since i got a 1/4 plastic adapter off ebay.

You could build a trim ring around the surround and put weather striping down between it and the door panel. Might make the panels bulge a little bit, but its better than crossing it over to 200hz.

I'll try reverse phase and if that doesn't work, I'll try to make some thinner adapters.

Is reverse phase bad for the speakers in any way? I can reverse the phase for the speakers from the head unit without making any physical changes. The only downside to it is the tweeters will be reversed too if that even matters.

why the hell would reversing the polarity help? Reinstall with a thinner baffle if you can or trim the insides of the door panel.

Someone previously mentioned reversing the phase may help. There's no way for me to trim the inside of the door panel, I guess I'm going to have to try a thinner adapter for them.

^^ I mentioned reverse phase, yes a thinner adapter will help.

build kick panels....probably would sound better and no loss of midbass

I wish I could use kick panels in there. The way the floor and factory kick panels are, there's absolutely no room for them.
