Speaker and amp combination advice please

[RussellJ]

Hello! I am new to the world of car audio! And I just want to ask if the following setup is wise/works at all without damaging anything! Be kind, as I may have jumped the gun with excitement and bought the wrong peripherals. But wanted to see if you guys think this will be fine to set up or a big no-no.

HU: Already exists in the car (Toyota GT86/FRS/BRZ) Sony XAV-AX1000

I've highlighted the power ratings. My worry is that the amps are too powerful for the speakers. I've done some maths (I think) and I could be overpowering my speakers.
Advice would be much appreciated.

Thanks and I hope you're all doing well!

You only need the four channel amp. Run the front speakers on channels 1/2 and run the rear speakers off of the Headunit. Then power the sub with channels 3/4 of the amp.

Thanks, Bobbytwonames. Will try that when I get to the build. Would I still be able to balance correctly from the HU when it's powering a pair and the others are connected through RCA?

If I went down the original route; amp power would be fine on these speakers?

Thanks,
J

If you go the other route then just buy a mono (one channel) amp for the sub.

Not too much power.

You could buy very powerful amps and turn the gain down as well. It's way safer to have too much power than not enough. We are all big fans of 'headroom'.
