system in J30t

Im looking for information on whether i can install some subs i have in my J30t without having to go with an after market Head unit. i want to keep the interior stock, including the head unit. If it is possible and if anyone know how i need to install this please let me know as i have been looking for this information for a while now.

thanks ahead of time for anyhelp anyone can give me,

i don't see why you'd need to change the head unit for a system.... consult your local audio place... they usually will tell you that it can be done with the origional oem, but they recommend an aftermarket because well... it's cooler.

It may be as simple as splitting off the Bose amp leads going to the rear speakers since that's where most of the bass frequencies go to.

The Bose amps are physically mounted to each rear speaker magnet. Take the input wires to the Bose amp and split off (don't disconnect) to go to an amp/sub.

The Bose amp inputs are low-level so you should be able to split the leads off to another amplifier which would in turn, power your sub.

i would recommend a better battery... those 12"s will slam though... no doubt on that... why not hit 15"s?

Low impedence input at amps are as follows
left side= white wire{+} and black /white wire[-}
right side= white wire{+} and black wire{-}
these are at the amp connector on each speaker{rear}.
