2000 watts :lolg: :lolg: :lolg: :lolg: :lolg: :lolg:
I also had 2 Pyle 12" subs. I had them in a horn loaded enclosure with a 150 watts going to each and they too rocked big time (til one blew).
What your friend has is a CRX and that car has an extremely high "cabin gain" when it comes to bass notes.
You have two quality subs and if you want their "full" potential you will need to spend a tad more. I recommend a JBL 600.1 which will run both subs at a 1.5 ohm load which is just fine with that amp (I run two 18W6's off a JBL amp). I bet you can find one for $225 or less, try
http://www.ikesound, I've had good luck with them. :cheers:
PS, if you build a good enclosure for the subs, your system will kick your friend' butt in SPL and espically sound quality. :smash:
