Yes, many cars and trunks have better horns.
Make sure you pull a set of horns
from same car.
See my Cave, Horn
Save the brackets on old horns.
(88 only have 1 horn. just add wires.)
Buy used get good 12v battery to test before
Cut wire(s) to horns because may have different plug(s) and may need to splice them. Some horn have 2 wires... When true the coil may or not be grounded thru mount bracket. Check either/both wire isn't connected to horn case etc. Example: Horn was mounted to plastic need ground wire but may still ground to mount hardware when use in another car. If you connected + to wrong terminal can fry fuses or worse mounted in Fiero.
Caution: Buying aftermarket horns often don't last even when made w/ well brand like Fiamm from local parts stores. Most are made cheap and not like OEM parts that Fiamm also makes.
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
