The sub requires an amp of some sort and the LT does not have the factory amp. Also the stock head unit does not have the outputs to send the amp the sound, or the accessory wire to send signal to the amp to turn on. There are ways a round that, and if you want to get into that we can.

to get sound i will just run a line output converter from one of the 6x9s in the rear deck, i would only need a simple amp to run that sub wouldnt i?

Factory pioneer sub is actually 2 cocentric speakers tuned to 2 seperate low frequency. I read somewhere 200Hz for center and 50Hz for outside, so you will need to seperate channels. I personally line converted my 2 6x9 into a 4 channel amp returning two channels to speakers and sending the low pass channels to the subs.

It sounds like two channels is not the right terminology. It would actually be more like a crossover frequency in a low-pass band of a crossover. Like a 6x9 3-way has three individual speakers with a crossover across the full range. Subs work in the lowest bands of the spectrum, so you would crossover below the amps crossover. I know that was actually more confusing. Bottom line, a 2 channel amp would not really cover this. A crossover is what you would require to split them, unless the speaker has it's own built in crossover (which would actually make more sense).

yea that was confusing, so if i got a 4 channel amp, nothing fancy it would be easy to run just the sub if i wanted to

Don't wanta confuse ya any more but you want a 2 channel amp for sub amp...not 4 channel unless your running the 6x9 off the same amp...
Get a crossover for the low freq. most amp will have this already...
An a RCA line converter to the 1 or 2 of the rear 6x9's (running 1 RCA is mono or 2 RCA is stereo which ya won't notice that much of a diff) they make RCA converts that will turn on the amp by the power going to the rear speakers..
And here another confusing part will ya run the subs in parallel or series? That's if your running 2 subs or dual voice coil subs?
