Amp suggestions for big radio's

[stang]

Hi all I'm looking for amp suggestions for a couple big radios. I have a RCI 6900 f25 and a RCI 2970 (on the way) Now I'm looking for a good amp for one or both of them. My base station will likely have the 2970 and with the Sirio Gainmaster antenna I am running I am limited to about 500 watts. On the other hand the 6900 will probably go in the Jeep I drive daily. I'm thinking I'll put the uniden PC122 in my other jeep with the texas star 350. Since they seem to work well together. Doubt I want to go much above a 4 pill so I don't have to worry about changing the alternator etc.. But I do want good clean amps with AB bias for sideband use. I also want to make sure whatever amp(s) I do get can handle the power of the radios without locking up like the 350 does being driven with the rci 6900.

I'm thinking I would like to get two alike or at least by the same manufacturer so the spare parts could be interchangeable.

Which brings up a second question what kind of spares should be kept on hand. BTW I live two miles down an old logging road. ROUGH is an UNDERSTATEMENT.

I also have the 2970 getting a switch to turn the internal amp off in case I want to run either barefoot or with a larger external amp. It's not the new 2970n2 it's one of the older models.

Thanks in advance for any pointers you may be able to give.
