can you install a subwoofer to the stock 1999 rr deck?

 

it shouldnt be that difficult, you can tap into your rear speakers for the audio signal, you just need this part that i belive is called a crossover but dont quote me on that just go to your local audio store and ask them. after that its just like any other sub install. it wont be as clear as a aftermarket radio but every one that i know with this setup is more than happy with it. hope i was some help.

 

should look into a line driver. the one my friends running is the Cache Cloc'd. Plug the speaker wire in one end, and out the other comes RCA outputs. also you can grab the remote from the line driver too. so everything right there in one spot.
