Well it looks like i'll be going with an 8" sub for now, i ordered a ct sounds tropo 8" 2 weeks ago from amazon but they never shipped it for some reason, i asked them to cancel on friday but they said it was too late, it was shipped today so they tried to reach dhl to intercept the package but couldn't so they'll refund me the money and let me keep the sub... wow now that was unexpected.
Guess i'll return the sundown and see how this 8" sub sounds, i'm sure it'll be loads better than the dinky oem one.
