Check the fuse for the radio - check inside the car first, driver side console - then the fuse box under the hood.
A 97 Mitsubishi Eclipse will produce a knocking sound if the ignition time is set incorrectly. This results in the valves opening at the wrong time.

You need to get a special wire harness especially if you have infinity sound system. See "related links".

You blew out the right side speaker
Could be a bad CV joint. It would make a popping noise.
Dead cell in the battery or corroded or loose battery cables.
bad cv joints check under the car and see if there is a rubber boot on the drive shaft connection to the wheel
A Mitsubishi Eclipse GTS is the model above the GT. The GT and GTS have similar motors but the GTS has a higher compression ratio, and a different intake. The GTS model also comes with all the bells and whistles such as leather interior, 7 speaker sound system, power seat, 17'' rims, front and rear disc brakes, and so on and so forth. I hope this helps.
It is behind the radio. So you will need to take out your center console and radio to get to it. It should be a little black box. If your turn signal still make a clicking sound, you can put your ear near it and hear the clicking sound.
By installing the driver for your sound card.
For me it's sound like you have problems with the right door. Check the rubber/palstic parts around the door.
