The two front door speakers and 2 dash speakers don't work, the front center speaker that is mounted over the top of the navigation screen works. The 2 rear door speakers and the sub woofer work.

Could be either, a setting on stereo head unit, fader may have been turned so that sound is just coming from select speakers.
Or could be your front speakers are not wired up or there is a fuse blown.
Note: clicking from turn signal does not come from stereo speakers.

Assuming you do not have factory tweeters then either is acceptable. Use whichever is easier to get to...door speakers if mounting tweeters on door or cd player if mounting on dash.

It would be helpful to know what vehicle these speakers are in? But just guessing I would suggest checking your crossover.

there is an amp usually built into the factory head unit or mounted in the dash behind the head unit. I would try running a new wire straight from the back of the stereo to the speaker and see if it works. if it does then you have a broken wire and need to run new ones

Thank you for using FixYa, have a nice day.

I have a auto repair shop and a customer has the same problem my genisys code scanner pull a radio communication code U0199 which is lost communication with door control module A. I will further diagnose this system and post later hope some of this will help you with yours

Not sure if you had a sedan, hatch, or coupe but here is the info you requested. Front door speakers measure 6.5" with a top depth of 1.75" (you have no depth problems here but any larger than 1.75 and you might have to cut out the factory housing.)

If they are door or kick panel speakers, you have to remove that panel to extract the speakers. Then measure them with a ruler; better yet, make a pencil outline of them (outside rim) and also where the mounting holes are. Then, when you buy new speakers say at Best Buy or some such, you will get the proper size, mounting and DEPTH. Unless you want to build all new mounting enclosures, you have to be sure of all the size measurements so that your new speakers will fit.

Wiring them is easy. There should be instructions. Speaker wires do have a + and - side, and if you cross them, the speakers will work but won't sound as good. Also be sure you have the POWER to drive your new speakers. Buy speakers of the same "impedence", measured in ohms right on your speakers.

Also, in here you can find the 1997 Honda Civic Service Manual.

Easy job, good luck (remember rated this help).

Top of dash must be removed. 2 bolts vertical in glove box 4 screws in defroster ducts, Remove 2 outer A/C air deflectors and 2 center deflectors. Be careful. Remove screws BEHIND A/C deflectors. Remove vertical screws along width of dash near speedo etc. Remove dash top and disconnect wires. Hope this helps
