Hello
Question if I take my 15" Tempest 8 ohm Dual voice coils .
When I wire the sub in parallel then I run my Nady xa-900 amp in bridged mono does the sub see that its a 4ohm load .
The amp is rated at 900W @ 4
Thanks
usually ch1 plus = plus ,ch 2 plus = minus
if the amp has a bridge switch it should be on that,if not ypu should reverse polarety on the second channel.
a manual would be helpful
