rockford fosgate 800a2 and subs?

i bought 1rockford fosgate 800a2 amp,  1 farad cap, for about 140 from my fren... i was using 1 JL (dunno what kind)and 1 jbl gt122... i know its bad to have a mix subs... my jbl is down... and right now i looking for some subs that can handle my amp... my friend told me to buy 4  Rockford Fosgate RFP4212 Speaker... is that good?? and how should i connect it if i get the 4 subs...

anyone who uses this amp as well??

any suggestion... or other subs that i should check out

thanks...

I would suggest just 2 he2's....do to the fact that if they are dual 4ohm (?) your amp is only stable at 4ohms mono at 800x1 and if you were to try and wire 4 he2's 4ohm, you acheive a 2ohm load....so I would go with just 2 he2's wired in series/parrell:

I've used that same amp and 2 HX2 12's dvc 4 ohm and tallied a 144.9 db from a sealed box. So 4 4ohm 12's should absolutely wail, choose the subs properly, make the box properly and especially important is to ensure a good ground with as low a resistance on the ground return as possible.
