Value check on a few items

I have been out of car audio for a year or two now and decided to sell my equipment. Problem is I have no idea what anything is worth anymore and was wondering if you guys could recommend how much I should sell some of these things for.

Fi dual 2 15 inch SSD with copper coils

Diamond audio D3 800.1 amp

Kicker 0 gauge wiring (Its been used)

I still have some rainbow comps that are not working correctly too but I want to try and fix them and keep using em.

truthfully i would put the ssd's @ 100 a piece, dur to the newer ones are better and sell for less than 200 new.

the diamond audio i would say $120-150 as back in 2008 people were selling them for 170$ used.

and the wiring, maybe cannot say as i don't know how much you have

Cool thanks
