ARC Amps? Help!

So heres the set up...'08 DCLB TRD Sport

Arc 10 sub...in MrMarv box.
HAT Clarus 6.5 components up front
HAT Imagine 6.5 rear
MrMarv baffles for speakers

The question is:
Do I go with the ARC XDi805 5 channel amp for all?
Or...
Go with two separate amps? ARC Mini's KS125.4m and the KS500.1m

Raammat and Ensolite have already been installed on all four doors and rear wall. HU will be the Alpine IVE-W535HD.

Thanks.

 

If location or space isn't an issue for mounting the amps I would go we multiple amps. Performance can be a little better but if the 5 ch. amp ever needs service the whole system is down until you get it back.
Just out of curiosity, what power, ground, battery terminals etc. are you planning to use? I'm also gearing up for a system like this.

 

I'm not sure yet on the terminals etc but have looked at Stinger per a friends suggestion.

 

Defenately go with seperate amps if you have the room. If you are not trying to beat the doors off and just want clean sound, go with the 5 channel. It will get the job done and will take up less room.

 

So...
Decided to ditch the drivers side rear plastic storage area also and now will have sub and amp rack across the entire back. Decided to go with two separate amps.
Arc Audio
KS 300.4 and KS 300.2 for the sub.

Thanks for your thoughts and advice.
