Because I do, and I'm in a constant quest to make it stop rattle.


Anyone have any opinions besides dynomatt? I've dynomatted the entire bottom of the trunk area (spare tire space), and a good 75% of the top, and I'm lost on ideas to get rid of the awfulness.


Pictures of it.

 

bump for advice.

You want some advice? Here's some. Stop bumping your thread after 26 minutes... This forum doesn't move that fast...

Isolate where the rattles are coming from and work from there. Don't just stick pieces of Dynamat (not dynomatt) arbitrarily... That's just wasting it.

 

Dynamat does not prevent rattles. Just reduces it.

For your trunk you want to do more than patchwork. Use a full sheet across the areas, works better than just covering up holes and vibrating points. Dynamat also makes larger pads (Dynapad) that is much thicker and will reduce vibration even more.

When you apply the dynamat, I suggest using diluted paint thinner and clean the area. Use a heat gun to get the sticking agent (monkey snout!) really tacky. Use roller and apply the sheet to the area. Roll the sheet so that bubbles will be removed and this will push the dynamat into the crevasses.

There are plenty of other methods that are your backyard trick, but very risky. Expanding foam is one for instance. The foam will reduce vibration quite well, but applying the foam can expand the panels beyond the welds.

 

Yes use full sheets. And layer. And unless you get dynamat extreme for under $2/sq.ft then goet another brand that works just as well and is only $1.60 to boot: http://www.edesignaudio.com/ed...id=52 shipping on a 60sq/ft roll is about $22 which is still cheaper than dynamatextreme

 

Do a better job covering with padding. You need to pad your trunk lid better, behind the license plate cover, and inside the fenders. Pull your carpet out and go to town.

A problem with Del Sols is the trunk is "sealed" from the pass. compartment almost completely, what I do will all Del Sols that we do a sub in trunk is to cut "vents" through the fire wall from the trunk into the pass. compartment. 94

My co-worker did that with his trunk and it expanded into his trunk lock. LMAO

Anyway, first thing I noticed...along w/ other responses is that "patchwork" dynamat won't help....like B18C said, you're just wasting it.

This is probably why I don't do big sounds anymore....I don't want to have to get extra **** to prevent rattles.

I thought that the fenders on the del sol were hollow and the only thing stopping them from being a passage into the car were the carpet/plastic on the inside of the car?

 

That's correct.

 

thanks guys, I appriciate the help.

 

dynamat "bulk pack"

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by JSPECSIR &raquo;</TD></TR><TR><TD CLASS="quote">dynamat "bulk pack" </TD></TR></TABLE>

Dynamat xtreme specs:
Thickness: 1.7mm (66.92mils)
Butyl
Cost: $2.77/sq-ft (bulk cost for 36sq-ft is approx $100 street (around $200 retail), this doesn't include shipping)

eDead v1se2 specs:
Thickness: 1.524mm (60mils)
Butyl
Cost: $1.60/sq-ft ($22 to ship 60 sq-ft roll)

If you like to pay more for something that does the same thing, we won't stop you.

Heck for the regular price of Dynamat xtreme you might as well get the newest eDead UE, which is 120mils thick, $3.50/sq-ft.

 

dynamat is too damn heavy.

i work at a stereo shop i dont pay " normal" prices. thats why my car with all the nice stereo stuff is double layered pretty much everywhere. but i do see your point, ive just never heard of those brands. the only other one ive seen is fat mat. good find

 

JL does make a sub enclosure that sits in the cargo space behind the seats in the cabin. this would solve your problem.

 

Ditto the above^^^... http://mobile.jlaudio.com/prod...=1403 94
