^^^ that would be a great amp for the price but the ap1800d will put out more and i assume you're looking for an amp for the dc level 4 xl in your sig.
Audiopipe AP1800D
PLANET AUDIO TQ1601D
Audiopipe AP1500D
Hifonics Bxi 1608
all of these amps will do rated. the audipipe amps and planet audio amps will do rated at 13 volts
if you need 2 amps get two audiopipe ap1500's with 4 dual 4 ohm dc level 3's so you can get a 1 ohm load for each amp or just get 1 audiopipe ap3000d and get 4 dual 2 ohm dc level 3's so you can have a final load of 1 ohm. audiopipe makes great budget amps
then of course i could get a more powerful amp for my re audio hc 15 and build a nice ported box for it and i'd be putting about 1800 watts to one 15 ported. but idk what will get louder 2 15's sealed or one really nice 15 ported?
well if i could see what the fuses are rated at then i could get an estimate but if i win it for that price that would be awesome even if it didn't do the full rated power
i just wanted to know if this amp would do rated http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=110572637687&viewitem=&sspagename=STRK%3AMEBIDX%3AIT
i couldn't find any info on it at all
ok what would be 2 good 15's that would work well in a sealed enclosure. budget is around $250-$300 for both subs i'd like the subs to be able to handle anywhere from 600-1500 watts rms total (300-750 rms each sub) the more power they can handle the better.

maybe 3 of those? i've used them and they get loud off of nothing they can handle about 4-600 watts rms
or
try and get 3 fi ssd's fully loaded
