Here goes, Ive got a 1995 Pontiac Trans Sport (i know it sucks) but its all i have until i can get my 1997 Saturn SC1 repaired (just got a promotion to assistant manager and it has been sitting in a garage since i crashed it a year and a half ago) so everything i have audio wise is in the van at the moment.
Setup thus far
Pioneer DEH-3700MP Deck Kenwood KFC-1669S speakers
and just i just bought 2 Kenwood 12's in a box from a friend. (he bought the used for 150, then his mom gave him that money back and said get rid of em because she didnt want him to have 2 subs in his car, so then i bought it off of him for 40 bucks

)
I dont know what model # the subs are, I know only the following, 350W RMS, 700W Peak, 12", dont know anything else (dont shoot)
What i want to know is how powerful of an amp do i need? im not trying to impress anyone here by having the greatest sounding system, i mean that combined 700W RMS and 1400W peak will be way too much for a van let alone a Saturn when everything gets transfered back to it. So i just want something on the cheap, amp wise.
Ill take a picture of the box incase someone is good enough that they can figure out the model of the subs (in a bit that is)
