JVC Amp or Other Recommendations?

[Honda]

disconnect speaker cable from amp, set multi meter on lowest resistance setting, put one probe on your ground one on a speaker wire, if you get a reading that's not infinite your gonna have a bad time.

how are the connections made to the speaker? ie did you solder the joins between factory harnes and your speaker wire and properly terminate the end of the wire with spade connectors.

When trying to get the resistance should the headunit/engine be on? The sound only occurs when the engine is running- and do I have to disconnect the ground cable from the amp?

I've connected the speakers by:
- cutting the harness out. Leaving 4 stripped wires.
- 2 of the wires were DIRECTLY soldered onto the speaker
- The other two remaining ends has been duct tapped
- Today, I've just overloaded the terminals with duct tape. I even went to the extreme of duct tapping the door metal just incase there is a loose end. I think it made it somewhat better Need to play it more to notice-
