The b 13 code is displayed for you next service with the dealer. It informs the dealer what type of inspection the vehicle will receive along with its oil change. It will be reset by the dealer, however, you can reset it by holding down the push button by the speedometer and then turning on the key till the dash lights come on. Hold the button until the b service light flashes then release it and then push and hold again till the b service light resets

Sound a bit like a poor power connection in the back to the radio, could be the plugs has worked loose.

If you don't have or can't borrow the keys needed to extract the radio from its housing, I'd have thought more or less any auto electrician / radio fitter / garage could check it out.

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).
