Have two a/d/s 10 inch subs and need help with a solid amplifier...??

Need more info. How big is the box, sealed or ported, if ported what's the tuning frequency? Is there a model number for the subs?

We need the specs of the sub so we can determine the best size box for your needs. This for home theater, correct?

If you use only one sub you'll have to wire it for an 8 ohm load since the Bash 500 can't handle a 2 ohm load. The amp will do 250 watts into 8 ohms with one sub or you can use both subs, wire them for a 4 ohm load and get 500 watts from the amp.
