Subs + Amp = Loud!?

Question

What is the best way to insulate the trunk of my car to stop it from rattling. I know about dynomat, but is there a better or cheaper way get it done?

Answer 1

Dynamat and similar products are your best bet, along with going around your car and finding out where there is rattles and fix them, but a cheaper alternative to dynamat can be found at your local hardware store, I do know that at Lowe's or Home Depot it is called Peal and Seal, Peal and Stick, or Quick Seal. It is acutally made for roofing, however it is made out of the same materials as Dynamat and is alot cheeper, and does the job. Check it out, usually in the roofing or lumber section.

Answer 2

Try tightening down anything and everything in your trunk. Make note of any wires or cable shields that may be vibrating against your trunk and either tape or pad them. Remove the back dash of the car and check your speakers for movement/tighten. Recommend padding the backdash where vibrations could cause noise - use foam cut to fit, making openings for speakers - check for third brake light shielding vibrating against the window - use weatherstripping to prevent rattles. Check your license plate - remove and place cardboard cut to fit behind license plate - tighten all screws - use top and bottom screws if applicable. Check your spare tire and tools for loose pieces and parts - check clearance between spare tire and bottom of trunk - use foam to pad if it will help. Check your trunk lid - should be able to see the trunk frame and the trunk skin - again, look for gaps or spaces that may vibrate and cause noise - make shims out of cardboard to dampen the noise. Check brake/turn signal/reverse wires for vibrations.

You might also be able to use insulating spray foam (Home Depot) for doors and windows to fill small gaps and spaces.

Try to orient subs and ports (if ported sub enclosure) appropriately - backdash, back of seats - to see if vibrations change. Consider sacrificing the bass for fewer vibrations. Can you fold your backseat down when you don't have passengers?

Good luck.

Answer 3

there is no really a way to stop rattling from the trunks of cars produce by the bass produced by subs........some of that stuff you can spray on will be expensive and it wont stop it completly and you will spent some money on it.
