2 x 10' Subs in Custom Made Boxes [WA]

Gents, 
  
I have for sale 2 x 10' Subwoofers in a fully enclosed custom made Box. Its designed to sit behind the passenger and drivers side seats. The boxes have been made to utilize as much internal space to get the best possible tones. The benefit of these boxes, compared to most other one's I've seen is they allow the seats to recline all the way back. There is no interference with the seats at all! 
  
Pictures supplied of the boxes out of the car and also in the car. No amp supplied as it broke. 
  
Prefer local pickup as they are not the lightest items in the world. Would like $100 for the Pair or swap for 2 channel amp (Suit 70W RMS)  that will fit under the car seat no problem.
  



 
I'll subscribe to this post as I didn't previously so forgot to reply.

They are an Alpine Driver....I dno't have the exact make/model with me at the moment. The boxes sit inside the cubby holes. However they appear to sit on the top. You can see a bump in the box design here is you compare pic 1 with pic 2/3. The benefit of this is they don't move at all once placed in the holes, and no extra tiedowns are required. It also gives extra volume to the box, which is somewhat limited usually.

Are they universal  or left right sepcific?
 
Are the boxes the correct volume etc for the subs?  Do they sound good?  I could grab one and chase can have the other.  I would need passenger side.  Which suburb are you in?
 
Might have an amp for Pete, would need to search for it to see if I have it.
 
Cheers
 

Arty, they are left/right specific due to the contours of the bucket space that they fit into. I'm sure you could mend these to suit whatever side wyou wish tho. (See the notch at the bottom of the boxes) With regards to volume vs speaker, I have no idea, these were the ones that came with the car when I initially purchased it. They sound ok, but certainly don't rattle the car like my current 12' sub. I'm not sure if this was due to the amp I was running them off at the time. I've had them out of the car for quite some time now.
 
I'm located in Bassendean - near Midland.

Arty,
 
I can attach it to my cars current amp for you to listen....I'll just disconect my current sub.
