I own 2 Alpine MRV-100M Amplifiers, which produces100W into 4 Ohms and 150W into 2 Ohms, and I wish to run them to 4 Clarion SRW 2541 SVC SUBS, which run at 4 Ohms each and the enclosure (sealed) has 1 pair of line inputs.
I wish to wire these subs in Series/Parallel, (if there’s a better way, tell me) which would produce a 4-ohm load. I understand the wiring, but now, when I add another amp it becomes a little unclear. Does this 4 ohm load get reduced into 2 when I add a second amp?
I want to use both amps, but I risk causing damage to my subs if one amp goes, right?
Nor, will not have as much power if I only use 1 amp to power these 4 subs?
Any suggestions? Thanks in advance.

You shouldn't connect the outputs of 2 amps together to a single output. I think those subs are 200 watts RMS, so perhaps you would want to either get:
an amp thats about 800 watts RMS @ 4 ohms
1.a class d amp that pushes about 800 watts RMS @ 1 ohm
2.(this would be the most useful I believe)
3.add another set of terminals to the box so each terminal would be at 2 ohms and each amp their own terminal

oops, sorry my labels are wrong (it's late and I'm supposed to be doing homework)
1.a stereo amp thats about 800 watts RMS @ 4 ohms bridged
2.a class d amp that pushes about 800 watts RMS @ 1 ohm (this would be the most useful I believe)
3.add another set of terminals to the box so each terminal would be at 2 ohms and each Alpine amp has their own terminal

thanks man. the best idea would be to get 1 amp. The system is working right now but its wired directly to each sub and spliced from the inputs connections.

IMO, the single amplifier would still be best to ensure that all subs get the exact same signal at the exact same time without worrying about any kind of differences that a dual amp setup could possibly have (just a personal preference). Oh yeah, your car link isn't working for some reason.
