Like it's been said it's not possible to have the coils on a sub test fine separately then have them read like that when connected. You do have the subs disconnected from the amp while testing right?Trust me ive rewired them 4 time. + to + - to- + to + voltmeter side, - to - voltmeter side.
Being dual 4 subs in parallel would be 2 ohms per channel, which your amp probably will support. It can support it for sure if it can be bridged. And your amp could've smoked a sub if you pushed it hard enough into clipping.
