Well that depends on whether or not you wired them in series or parallel and whether or not they are single or dual voice coil. Search around for how to wire series and parallel. Series will give you 8 ohms and parallel will give you 2 ohms. BTW that amp puts out the same power for 2-4 ohms.i have 2 10" subs hooked to a 500/1 amp. the subs are 4 ohm each, since they are hooked to a mono amp does this mean they are now running at 2 ohms each
since the amp is mono i ran one speaker wire from one to the next, and then up to the amp, they are single voice coil, i am trying to figure this for tuning, to set the gain voltageWell that depends on whether or not you wired them in series or parallel and whether or not they are single or dual voice coil.
