Answer 1

Errg, the easy answer is yes, but it will suck so bad you will probably cry. You could either cut out a speaker, or wire in the sub in parallel with a back speaker, but it would sound like c**p, and you will be asking too much of that head unit, your going to need an amp. Not a huge deal, send from the Headunit to the amp, All that needs is a power cable, dont forget an inline fuse though or it could get ugly.

Answer 2

No you need an amp. For that sub you need an amp that produces 200 RMS @ 4 ohms (yes ohms are important).

^that amp should work well because its rated for exactly what that sub needs to run properly.

Since your new to car audio i would see about having a friend who knows car audio install that amp and sub or go to the local audio shop (please not best buy or circuit city) and pay them to install it.

hope this helps.

NO

all subs will require an amp because there are no radios that have the necessary RMS wattage to power a sub-- if you hook a sub directly up to a radio you run a HIGH risk of damaging the sub and the radios internal amplifier

too little power can also damage your subwoofer — in fact, it's actually more common than damage caused by overpowering.

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

when the amp (or radio) does not have the needed RMS wattage you will send it into clipping

Clipping

Clipping occurs when an amplifier is asked to deliver more current to a speaker than the amp is capable of doing. When an amplifier clips, it literally cuts off the tops and bottoms of the musical waveforms that it's trying to reproduce, thus the term. This introduces a huge amount of distortion into the output signal. Clipping can be heard as a crunching sound on musical peaks.

that causes distorted sound which will damage your subs (because distortion is the main cause of speaker damage)

so you could fry the radios internal amp from asking too much from it and melt the voice coils in the sub

Answer 4

It can be done,but useless...Subs are made for low notes only,you need a amp with crossovers to drown out the highs,this cannot be accomplished without a  amp.
