question for audio experts

amati5 · 07-02-2004, 04:18 PM

I have a mid level audio system and whey playing high bass music, it vibrates and buzzes the stuff in the side pockets like my kids' head phones. If I remove the door panels and add some rubber washer under the speakers' screws (I did this to the dryer and it runs like new

, will that help? I plan on getting felt lining for the side pockets but I think rubber washers is the cleaner solution.

Thanks

nope you will need to mat the doors with some sort of sound deadener on top of the metal--that will kill all rattles (dynamat, b-quiet, or some other cheap derivative from home depot)

rubber washers and felt will help, but smoke is right, some sound deadener is really what is needed. the dynomat IMO is overpriced, go with the cheap stuff, it's almost as good and WAY cheaper.

Sound deadener is great! I usually accentuate the harder areas and plastic to metal areas with an undercoating spray that you can get in most auto parts stores.

I usually do the back of the panel that covers everything too... but just be careful of openings in the door metal, as it can get on the window. Same with the back of the panels, it can spray through.... usually masking tape works for that. For the metal doors, just make sure the window is up.

But that's really for a true audiophile that doesn't like any rattles or vibrations. Haven't done it to the titan yet, but it'll happen soon!

Thanks for all the info. I didn't see the replies before the weekend and added some rubber washers behind the screws, didn't help much. Some of the rattles actually come from the speakers themself couldn't handle the base. I think the stock speakers are too weak for the (stock, mid level) amp. I may upgrade the speakers and use sound deadener.

thanks

edit: I meant bass.

No, it's more like the oem amp is too weak. Upgrading your speakers will do little, if not sound worse without more power.

I removed the door panel and looked at the speaker when the cd was playing (song with high bass) at medium level. I saw the woofer cone's ring vibrated badly and made the distortion sound and assumed the either the amp is too powerful or the woofer cone's ring is too weak.

Both the amp and the speakers suck. The amp is not too powerful, it is underpowered. I have been advised if you merely replace the speakers, you will stand a good chance of ruining the new speakers because of the underpowered amp. If you turn the fader to the rear speakers, you will note that they suck in the extreme.

yours and Sam's post are quite the reverse of what I've been understanding (which is not much, btw). I've always thought that if the amp produces at certain output level where the speakers can't handle and that's when they (the speakers) start to buzz. If you don't mind, please explain a little more in details.

I don't listen much to the audio system but I want a matching amp/speakers.

Sammy Sandbag · 07-07-2004, 02:41 PM

Underpowered speakers distort or clip, causing the uncontrolled movement of the cone. Common misconception is that when you crank the volume and it distorts, it is because of too much power. However it is usually the opposite, where there isn't enough clean power to produce the sound clearly at the volume setting. Clipping causes the voice coil to over heat and will eventually ruin your speakers. The oem amp in the mid grade and RF models is very underpowered and this is why you get a distorted signal at mid to high volumes. Simply replacing the speakers will not solve your problem, and as bestatchess pointed out, you will probably only ruin the speakers.
