One of my vehicles is a 97 EX coupe and I can tell you some common pitfalls with this vehicle.
1. It has a weak alternator. Depending on your stock alternator it will be between 70 and 85 amps. It is hard to determine because Honda uses either the Mitsubishi or Nippondenso depending on what was available when your car was assembled. Also, changing the alternator is a royal PITA. Not hard, just time consuming because you need to remove a bunch of stuff. This is especially true if your replacement alternator has an overdrive pulley on it!
2. You have an Electrical Load Detector circuit. What this does is ramps your alternator voltage back when there is no load on your electrical system. It is a nice pretty square box inside of your under the hood fuse box. In other words, if you get a HO alternator, it's output will be controlled by the ECU based on your electrical system's load. I went with a reprogrammed ECU to do away with the ELD circuit, but, my vehicle will not pass an emissions test now! Lucky for me they don't do that in my parish (county for the rest of you)!
3. You don't have jack for mounting depth in the front doors. Conversely, if you use MDF spacers, you can't use the factory grills to maintain a stock/stealth look without a lot of customization.
4. Your doors have molex plugs. It is challenging to find room to run two sets of speaker wire through the driver's door if you want to run an active setup for your mid and tweet. Right now I am running passive, but the wheels are turning for when I run active. I may just pull the fenders and drill new holes for the door speakers. I need to fix a dent in my passenger side front fender anyhow...
5. Removing the rear deck speakers is a beyatch. If you run rear speakers, I suggest mounting them from the bottom of the deck so you don't have to disassemble 40% of your interior just to get to them again.
6. You don't have much space under the hood for a decent sized battery. I used a Kinetik HC1400.
I think I covered all the fun and games you will encounter. Good luck!
