Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

INSTALLATION
Figure 3. Mounting the GTO8626 and GTO6426. NOTE: The GTO8626 and GTO6426 speakers are designed to be installed under factory grilles. Consequently, no grilles are packaged with these models. Figure 4. Mounting the GTO626 or GTO636 using the supplied grilles. Figure 5. Mounting the GTO626 or GTO636 in 165mm speaker locations. Figure 6. Mounting the GTO626 and GTO636 in standard speaker locations.
NOTE: The GTO326 mounts similarly.
Rotate tweeter so it is angled toward the listener using the UniPivot� (patent no. 6,002,780) feature on the GTO526, GTO626, GTO926 and GTO8626.
NOTE: The GTO626 and GTO636 use an adapter to fit a variety of different 6" openings. Select an appropriate adapter ring and secure it to the vehicle using the sheet-metal screws provided, then attach the speaker to the ring with the machine screws.
