car or home?

i would try to find a good 400 wrms amp you can afford, overpowerd subs are so much more fun than underpowerd.
do your homework here,

is the sub 8 or 4 ohms. cause i get the dhm108 and i could only get it n 8 ohms. so i got the HIFONICS 1500D it puts out 250 watts at 8 ohms!!! it was the biggest amp that was for a good price. i got it online at sonicelectronix.com. but i've been ont their site lately and i haven't been able to find it. and it's convient because u won't have to buy another amp if u want more subs? this thing will run 4 of those subs easily with plenty of power. which is what i plan to do. i'm currently running 2 of the DHM108s in a WO and it sounds insane.
