First of all I'm not looking for ground shaking bass but I would like an opinion on getting the bazzoka tube and puting it in the back like stock or

getting a tc 10" inch sub, take it apart since it has the stock harness amp and sub, then jam it into an ed design underseat sub?

the bazooka per ebay would come out to about 150

and the tc sub would be 150 + the ed design enclosure of 85 more if I want the ed subwoofer SQ10

I like the plug n play option of both of these

 

you can get a powered sub and shove it under your seat for about the same amount of money or there abouts

 

I've looked at the infinity basslink II and it wont fit

Any others that might?

other wise should I do an upward or downfire sub?
