so if i get the bazooka sub oem all i need is the wiring harness to connect it to the stock head unit?

 

I believe so, I think toyota just jacks up the price so high because it's one of the only cars with an option of a subwoofer. I was thinking about doing it myself too, but decided to go with the factory installation. Full warranty covers the sub i think if it blows

 

how hard is it to run the wiring harnesss?

 

its 100w for 500 dollars that a little high u can get one with more watts for less money...

 

can you change out the sub

 

break that down for me haha
