I have 2 12"alpine type are subs that are dual 4 ohm and a kenwood amp that is 500 watts at 2 ohm and 300 watts at 4 ohm. Can I hook up my subs to get a 2 ohm load and how? It's a mono amp. I can only find wiring diagrams that show a 4 ohm load and a 1 ohm load . Or should I get a amp that is 1 ohm stably? Can some one please help me.?

If you have 2 4 Ohm speakers, and wire them Parallel(plus to plus and minus to minus)
You will have a 2 ohm load.
