6 channel tri mode on 100.4 questions as well as comp questions

[SuBXeRo 1]

I understand the concept of bridging and individual channels and the impedences that the amp handle. What i dont understand is that load that would be created in a 6 channel tri mode on the 100.4. I am planning to get this amp and rainbow slc 265.25 ng's for my fronts and rear doors and they are 4-ohm comps. Np with that but i was peaking at the manual and noticed you could do a 6 channel tri mode and if i added mid bass or subwoofers, what wattage and impedence would be put onto the amp. This is a concern because i don't want to ruin any speakers that i add.

I am really trying to create a good sounding system, i care more about bass created by speakers than having to add subs because i would have to do an IB or put a box in which i dont want to do if i can help it. I have had subs and my taste changes time to time and right now, a good, clear, responsive system is what i want. I am replacing my front comps and adding comps to the rear doors since i have a woofer mount i only need to drill for the tweet and then i have 2 6x9's in my rear deck. the 6x9's in the rear deck i was going to nix i think and just do the front and rear doors but from what i understand the rear deck works well for midbass.

Thoughts?

get ready to hear why you shouldnt install those rear comps. also, I would have to bet that if you were running 4 ohm loads to each channel with the comps, and also ran a bridged sub off the same channels, and it was a 4 ohms sub, the 4 ohms would be "split" between the channels. so it would be like paralleling the 4 ohm load from the comps with the 2 ohm load from the sub(half).

thats gonna be something I have to look up cuz i forgot the formula, its easy with similar ohm loads, but I dont know off hand how to do different ones.

I believe if you ran a pair of 4 ohm comp sets, and a 4 ohm sub on the same channel it would be 1.33 ohms, which Im pretty sure the SA amps wont do, dont think many amps do that. of course they probably would handle it if setup properly, but not under warranty.

better run a 4 ohm DVC in series or an 8 ohm sub so you can have a 2 ohm stereo load.

well i looked in the manual and it didnt really explain any of it just said 4-8ohm load which isnt very descriptive. What is the reason for not installing the rear comps?
