Does anyone know the value of memphis audio items i am trying to sell some.

[YarisSedan]

So I have a memphis audio EQ model no 16-EQP4

2 subs 12" studio subwoofer

1 amp PB400

trying to find the value to sell them on craigslist but from i can gather is the pricing is set by the venders. So it makes it difficult unless i go to one of the venders in my bay area that sells memphis and see what they charge new. Was wondering if anyone here knows thier value new and what would be reasonable to sell them used.

Depending on what i can get for them i am thinking of putting in the amp and wiring it up to 1 of the 12" subs for my car.

I would do 2 but to me that seems too heavy and kinda overkill for a little yaris.
