I have those for you right here.

all the squabbling aside, if you are putting in any sort of extra bass, you are going to want to do it the right way. If you are keeping your factory radio and speakers, you use what is called a line out converter. What that does is take the signal from your back speakers via piggy back leads into a converter box. The higher end boxes come with gain controls to boost the signal from the speakers. You than run RCA cables from the converter box into the amplifier. You will need to find a constant power source to run to the amp for the turn on lead. It'* recommended you put a switch of sorts in the line somewhere so you have the ability to turn the amp off and not drain your battery. Next you need to run the power and ground cables. Keep in mind you want a fusible link NO MORE THAN 18 INCHES from the battery. The ground should be as short as possible on completely bare metal, no paint or rust whatsoever. What subwoofer and amp you choose depend on how much bass you want. If you want tight accurate bass, a pair of 10s in a sealed box would be good. If you want loud, booming bass you'll want a pair of 12'* or 15'* in a ported or bandpass box. Keep in mind that you want your amp RMS rating to equal that of the total RMS rating of the subwoofers. Also you want to watch the ohm rating that is going into the amp from the subs so you don't blow the amp or the subs or both. (I've done both before and trust me it'* not pretty) You'll want to be sure you have solid connections and don't over crank the gain so it sounds good. Any questions pm me, i'd be more than happy to help
