the W7 is pure bass...

if you have the stock sub still working and a new sub in the trunk, the air the bigger sub pushes will push and pull on the stock sub, cancellation effect.

i tried it, also a 10' and a 12' wont work together, unless u got some crazy install work done.

 

wow good stuff lol. but idk how i can get that sub out from the back especially when my cars a lease and i dont think im keeping it.

 

oh then i dont know either.. haha

 

haha is there any good subs that include vocals with it as well or no?

 

subs are not designed to do vocals.. too high of frequency ... most vocals are between 2-4khz whereas subs are designed usually for 120hz or below..

i just unscrewed my stock sub and unplugged it. i had my shop design the port for my sub to be upwards facing so the port points to the hole left by the removal of the stock sub. i'm using a jl 12w6v2 .. i do get rattle when i crank the bass.. but for non-mirror shaking bass levels... i have no discernable rattle from the drivers seat.. from the outside, i can hear some very minor rattling but its not very noticeable..

obviously if i crank it.. then theres quite a bit more rattling.. i just don't want to dynamat my car since i keep adding weight to the car..

side note: has anyone else noticed reduced handling since installing a sub? it seems to me that i have quite a bit more body roll now that i've put in the ported sub. (i have stock suspension so far) will the underbody bracing/sways help a lot with the body roll?
