I Just got this 95 Honda cicic 4dr ex. I put a 12 inch type r alpine a 600 watts amplifier v12. the trunk is rattling a lot any help
also I cant seem to get it to sound just right I also have a alpine head unit

 

I would first try some type of silencer. Dynomat is good, tsunami silencer I found is pretty good, there actually is a whole bunch of different brands that will pretty much do the same thing. I would first try ebay before you go to any retailer and make sure it has the foil back, ive found it works a lot better then any normal universal kit. After you buy that, lay it in the inside of your trunk lid, and if you have any door panel shack, lay it there. This should decrease if not remove all of the rattle.

 

*AHEM* check the sticky at the top of the section
