Please help the new guy, 5 channel wiring for comps and sub

[shortbuss45]

I finally bit the bullet and decided to put something together for my truck. I am going with an Alpine cda-9857 head unit, Rainbow slc 6 1/2 components up front, an old but new JL Audio 12w07 single coil in a sealed box, and an old but new Alpine MRV-F352 5 channel amp. I am not trying to win any events by anyyyyyyyyyyyyyy means just an upgrade from the 3 speaker am/fm pushbutton radio original to my 80's Land Cruiser.

My question is how I should wire this up to get the best possible use of this amp. It calls for 8 gauge wiring would 4 gauge be better? Should I bridge the first four channels for the components and run the fifth for the sub or? How should the sub be wired (it is 6 ohm) Should or can I bridge 3/4/5 together for the sub? I know my knowledge level is novice but asking questions is always the best way to get better. How many watts are gained RMS and peak when the four channels are bridged for the components. Should I utilize two sets of rca's for this install. Thanks to all in advance. Here are the amp specs..

Power output RMS Continuous power for (12.0V, 20 Hz-20kHz) (ch1-ch4) is: 30W per channel into 4 ohms, 40W per channel into 2 ohms, 80W bridged into 4 ohms.

Ch5 for (12.0V, 20 Hz) is: 100W 4 ohms.

Power output RMS Continuous power for (14.4V, 20 Hz-20kHz) (ch1-ch4) is: 50W per channel into 4 ohms, 60W per channel into 2 ohms, 1200W bridged into 4 ohms. Ch5 for (14.4V, 20 Hz) is: 150W 4 ohms

Use 4ga. wire. Bridge channels 1/2 and 3/4 for your rainbow components, and run your w0 on the sub channel.
