Lol commodore be careful of boot rattle

Dont want to hi jack thread Juice, but while we're talking car stereo's.........
Why do some CD's play in my old Prado, and some nothin', zip, ERR1!
What is the best way to clean a car CD player, tried the old compressor blow out/in!! probably not the answer right?
Thanks

Yes, it's worth doing.

I use the sheets of foil backed bitumen sheets that Jaycar used to sell. I stick on the inside surface of both the outer skin and inner skin. It's very easy to apply, you just press them on and they stick. Also pull out the back seats, and put them on the wheel arches, and other bar metal surface I can see.

Then you should cut out sheets of MDF to block all the service holes in the inner door skin.

Lastly, I pull out the carpet, and lay 3/4 inch thick felt over the entire floor of the cabin, then re-install carpet and seats.

I've given people a lift in my car, and without them knowing what I've done, they've commented on how quiet it is inside the car.

Tweeter placement can be critical. I had my tweeters on long lengths of cable and stuck them on with blu-tack, trying several locations before finding the optimal location and securing them permanently.

I watched a TV show on the Rolls Royce factory recently, and basically their sound proofing was almost exactly what I've done.

Has old mate not heard of the ford taurus and the AU falcon?? 2 of the worst cars ever made

Mind you I always had a soft spot for the T series. They always sounded pretty tough

No the dynamatt will not increase the bass at all ever . . .what it does do is stop the panel from resonating and reduce road noise



it will not put your speaker in a better acoustic environment that is dynasorb



dynamat will improve the overall audio experience by improving (reducing) the background noise



have it in my commodore and i have fitted it to many customers cars

. . . . you need to cover about two thirds of any panel to be 100% effective - If you are on a budget then placing patches directly behind the speakers will make a considerable difference and you can add to that latter if you like.


It is usually cheaper to just buy a small pack of dynamat rather than the speaker pack (per square foot/meter)


. . . . .wipe the surface clean with meths first to ensure good adhesion you do not want to end up with a melted pile at the bottom of your doors after hot weather (happens more than you think people stick it to the dust layer instead)

as others have already stated the cheaper products are not as effective, they work but you get what you pay for


Also if you're getting splits for the front end of the commodore take of the panels at each end of the dash and place the crosovers in through there to reduce any chance of induced engine noise.


tip- if your mounting the tweeters in the factory position then at the crossover set the titanium ones at -3db fabric ones to 0db/+3db

one cheap way to improve the sound from your speakers is to source wooden speaker mounts to replace the plastic ones mdf is fine and most audio shops will have them readily available for commodores

oh yeah +1 to what Harrow said all good info

Thats awesome, thanks for all the advice.

Im going to have to stick with the standard head unit as its got the IQ system and is all tied in together.
I'll get the bulk pack of dynamat and after doing the doors ill have some left over.
I've got splits for the front so the tweeters are going where the stock pretend tweeters are.
Was thinking of making mdf mounts anyway as the fronts are 17cm and a bit bigger than the stock ones, but I'll do it for the rears also.
Just hope the sound out of the IQ system is up to it


Hey VB Man, does your Ford loving live in, want my old Cougar. (Im talking about my car not my ex.) Actually if he takes one he can have the other for free. Its been around the block a few times, high mileage, temperamental, noisy, prone to breakdowns and looks a bit tiered. The fords good though.

Nah, he's already got one of both of those
