Adding an amp and 2 more speakers to boat system issues?

[EIC001]

I currently have a Sony Mex-M100BT. It has a built in class D amp at 40x4 RMS. I have 4 6.5 kicker coaxial speakers (65RMS and 4ohm) hooked up to the head unit. I want to add 2 8in kicker speakers (150RMS and 4 ohm) to a kenwood M3004 4 ch amp (50x4 RMS and 150x2 RMS bridged). My plan is to bridge the two 8in speakers to the sub and keep the 4 6.5 speakers on the head unit.

Are there any issues with this setup or any help in getting it to sound right?

Thanks for any help or insight.

u good, bridge 2 channels to each sub (as long as the subs are single coil)
