Well, yes but for a newbie it wouldn't be recomended. Even for a pro it wouldn't be either. Reason is that mix matching all that crap would be a bitch to tune it right. If you ever seen a properly done, multiple sub and amp system, they are all the same thing. Like my big d2400 amp I sell, it is set up to run Master/Slave so that way you'll know you have constant power and frequencies to everything. Otherwise, you'll always be messing with crap trying to tune it.
If you really want to use what you have, you'll have to pair up things that match together in their own enlcosures.
