Ok he said they where Rockfard fosgates Punch AT's. Does that sound right.
I searched high and low and haven't found any Rockford sub called the AT, even WinISD's data base doesn't have anything close to that. All Terrain speakers, sheesh

.
Regardless of model, find out what impedence they are, 4ohm, 8ohm, 4ohm DVC, etc. That's one of the biggest deciding factors in picking an amp out for them. Power handling is also important, although if you go with too large an amp it's no big deal. Avoid cranking it till distortion and the subs will live forever
(unless the sun eats the surrounds or something like that).
Anyway, the amp I have is an older Rockford DSM 200ix. Very top of the line back in the day. It's rated as:
100 x 2 @ 4 ohm
200 x 2 @ 2 ohm
400 x 1 @ 4 ohm
After searching around I found most actually benched high 500's to low 600's. The guy I got it off claimed the birthsheet (that he doesn't have anymore) was 744 rms. I don't actually believe that, but they are underrated.
It's missing the end caps, but I found them at
www.4caraudiodeals.com for $15 a pair. The guy I bought it off has them, but kinda isn't living with his wife anymore right now and doesn't want to do a full house search to find some stupid caps.
This amp goes from about $90-$130ish on Ebay, I'd like to get $100 (and you don't have to pay shipping!).
This is a pic of my actual amp, it's sitting on my desk now..

Sorry for making this an ad here, but I figure you may be interested and it's a pretty good deal (I need money!!!! The Toyota needs a timing chain!!!).
