We can get ya hooked up
Since the subs say 2 or 8 ohms, they would be dual 4 ohm voice coil. Wire the two coils on a sub in paralell for a 2 ohm load, or in series for a 8 ohm load.
What brand are they ( it )
is there one sub, or two
do you have am amplifier already?
what is the wattage rating on the amp, and on the subs.
the stock stereo amp will not really do a good job pushing a sub. It just doesn't put out enough RMS power.
and as far as the ohms go for the sub to work, they just need to be matched up with what the rating on the amp is.
If you could provide a link to the subs you purchased, and to the amp you have ( if you have one ) that could also help
I would have posted here for ya sooner, but I just got home from work.
