Help wiring amp & head unit to leisure battery

[Tom Keyte]

Hi, thanks in advance for any help. I've added a leisure battery to my van, using the wiring in this video: https://youtu.be/oOQHe_cZtI4?t=1044

I have this amp: https://www.caraudiocentre.co.uk/product_m-pioneer-gm-d8704_p-41014.htm and this head unit: https://www.pioneer-car.eu/uk/products/deh-s3000bt
 

I'm assuming the head unit will be fine if I wire it in to the fuse block (this one: https://www.amazon.co.uk/gp/product/B01IVRC9RA/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1).

Should I re-wire the permanent or ignition switched terminal from the back of the head unit to the fuse block.

And my main question...

For the amp, Should I be connecting that via 16mm cable straight to the battery (or to the isolator switch in this case) and does it need its own fuse.

Thanks

Tom
