I just purchased 2 kicker comp 10 in subs, with a mtx 300 xd 1 channel amp, They sound horrible, almost like they are blown, they are 4 ohm's, should they be 8 if I am running 2 of them? I have n ot played with speakers in a long time, so I can't remember what ohm's they should be.

Most car audio is 4 ohms . home audio is 8.
Cant give you much more advice from Mexico though.

depends on wiring. the LOWER the ohm rating, the harder it drives the amp. example: an 8 ohm load on the bass amp i have drives the amp to produce 220 watts, whereas a 4 ohm load drives 380 watts. More power yes, but it also stresses the amp more, runs less efficiently and creates more heat.
as for wiring, take two 8 ohm speakers, wired in parallel (both positive and negative leads going to the output jack) creates a 4 ohm load. Wiring in series (positive output jack to positive terminal of one speaker, that speakers neg terminal to other speaker positive, that speakers neg to neg side of input jack) creates a 16 ohm load. when dealing with speaker pairs, parallel wiring halves the rated ohm, whereas series wiring doubles it.
the same for component systems. two 8 ohm speakers hooked to one side of the amp produces a 4 ohm load, as this is parallel wiring.

In the past, car stereos were rated to run on 4 Ohms. But to be sure, check with Radio Shack or a stereo specialty store near you.

8 ohms is best make sure that your complete system is 8 ohms or 4ohms to include your receiver and amp higher ohms going to lower ohms can blow your system or make it sound horrible

Car stereo's are typically 4 olms and home stereo's are 8 olms. Check to see if you amp has an olm switch on it and make sure is set to under 8 olms
