The cables are long enough and all the loops can be easily reconnect. The fuse has been interposed at the red cable ... So everything is ready for installation.
In car audio forums I had read much about wiring, because the speech was by then min. 16mm² and best more ... that was me then but too expensive. It may be that you> 20mm² then needs at 500-1000 watts RMS, for my 300 watt amplifier + Sub have then 10mm² passed easily.
To RCA cable, I can only say that I would have noticed anything negative. It just does the job and at a reasonable price.
All in all, a top product for beginners. I can only recommend!
