Replacing Symphony HU - new HU up to the job?

Hi guys,

I was given a Vibe Pulse Alloy 3 Series active sub and a wiring kit for it and I was going to attempt to connect it up to the standard Symphony HU myself using the RCA adapter (complete novice), however, the Eonon D1310 HU caught my eye on Amazon and I was wondering if the 4 x 65W would be suitable to run all of the standard speakers in my Fabia. I have heard there are eight speakers so would I need to find a HU which has 8 x ?w, or can I run the speakers in parallel?

Thanks,

Glen
