I have 2 alpine type r swr1243d 4ohms and a kenwood 9105d amp. How do I hook it all up to get the full 900 rms at 2 ohms

With your 1ohm stable amp you can do parallel on both voice coils and both subs to amp. Positive and negative terminals are internally bridged. So you can hook one sub to each set of terminals.

The only safe way to connect those speakers to your amp is the second picture on the link provided below. If you had dual 2 ohm drivers you could achieve the 2 ohm load you desire. You have dual 4 ohm drivers, your choices are 1 ohm or 4 ohm.
