even if they have the same or similiar TS parameters?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
sounds good.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
Good point but some setups or just personal prefrences require a plate amp.:TI 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.
thanks nickHi, 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:
