I posted a while back asking where the best place to tap into the factory stereo was and got some great help. So this weekend I finally installed the sub.

It's a 10" Pyramid sub with a sony xplode amp. Definately not mind blowing equipment, it's juststuff I've had for a really long time. At some point, I will upgrade to some nicer stuff, but for now, it does an ok job.

My one thought, I have an 8" Rockford Fosgate sub that I forgot about when installing this, since the size of the box is so small, do you think the 8" would sound/perform better than the 10"?

 

I would look up the specs on that pyramid and the rockford, what's the recommended airspace for a (I'm assuming sealed?) box for each of them. Then figure out what the volume of your box is, with those numbers you can figure out which sub will operate better in the box. (If I had to guess I'd say the Rockford)
