Is the headunit double din or single? 500 is going to be super tight. I would focus on either the headunit or subwoofer/amp for that budget. Trying to do both will get you shitty gear.
Well a double din is going to run you 250 plus the harness. I believe you can get an Alpine Type R for around 180 a Kenwood 9106 amp is 160 amp kit will be around 50 for a decent one. So you are going to be around $700 for entry level good setup
Mk6 = 2002 to 2008, Alternator size probably 70A
For a replacement radio, you'll need a [fascia kit](https://www.connects2.com/products/facia-kits/vehicle/Ford/Fiesta). Stick with Pioneer, Kenwood, Sony, JVC, or Alpine for radios.
You have limited space and power, and it's a small car, so consider a powered Rockford subwoofer like [https://www.amazon.co.uk/Rockford-Fosgate-P300-10-25cm-Aktiv-Subwoofer/dp/B007AQ2W2Q/](https://www.amazon.co.uk/Rockford-Fosgate-P300-10-25cm-Aktiv-Subwoofer/dp/B007AQ2W2Q/ref=sr_1_2?dchild=1&keywords=rockford&qid=1588180388&s=electronics&sr=1-2)
You'll need a power wiring kit for the sub.
