It all depends upon the impedance of the drivers and what the minimum load that the amp can handle. what equipment did you have in mind?

So your thinking of doing 2 completely different subs on the same amp? That isn't a good idea, if they were both the same sub on the same amp i'd say go for it. Or 2 different subs on 2 different amps and you'll be good to go.:T

I would most certainly choose a different setup, even though the subs have similar T/S's they are 2 different subs that will react completely differently putting an unknown strain on the amp or possible failure of it. Your best bet is to choose 2 of the same subs.:T

I generally feel that if you need something above 500W or want to power multiple drivers (especially 18") - it's a good idea to consider an amp like a Behringer 2500/4000.

I feel that above 500W it becomes less cost effective to use a plate amp.

I have no experiance with any of those brands but have heard good things about the o-audio and the Bash but being that the ED is the more powerful of the 3 that is what i would choose. I'm a firm believer in having more power then needed (when used wisely).:T

Good point but some setups or just personal prefrences require a plate amp.:T

Choose a driver and cabinet design and what you are looking to get out of it (music/movies) and we can help you abit better.:T

Jim is right, that it is easier said then done but with the proper knowledge and tools it is simple to equalize gain on 2 seperate amps. I would suggest for simplicity just getting a more powerful amp that can deliver the power needed for the subs you have in mind however.:T

Hi, I confirm you should get a standard 2 channel rack amp powerful enough for the biggest sub, then install the amp (or not) in one of the cabinets and connect each cab on each output of the amp. This will allow you to setup each sub at the right level without any risk of failure from the amp as if you connected the two subs on one channel only. As you use a powerful 18, I'd suggest a (real) 2x500RMS under 8ohms minimum. :nerd:
