i have a 1.7 sealed enclosure and put my cvr in here and i thought it wasnt going to give it bass but i couldnt believe it. great buy!. just be careful on over filling your box they recomend only half of the box is filled with it. and cheap for more bass.!

Review written by Aj from Haltom City Texas
truthfully i didnt compare the sound of the bass with or without the polyfill, i just read up on what its supposed to do and it supposed to make the box think its bigger than it really is so im just guessing it works and also for $3.99 it was worth it i only used abouthalf the bag in about a 1 cubic volume box in my single cab dakota so u can do a very large box with this bag it goes a long way and if it does what people say tis well worth it expecially when you have limeted space like i did.

Review written by Paul from Cadillac, MI
It's awesome and helps give a more "full" sound to a smaller sealed box, so if your short on cash and want more sound this is definitely a way to go. But, as someone stated earlier make sure to be careful when placing it in the box and not to "over stuff" so that your subs won't over heat and end up costing you more money.
Ordered one car stereo through Sonic, had some questions about the included installation accessories which were answered quickly and more importantly accurately. Was so happy with the purchase I ordered another one for my wife!
