I bought an after-market harness adapter to wire my stereo to a 1991 Ford F-250 pick-up, the prior owner of the truck installed different speakers and now I have power going to the deck, but no sound from the eakers, what do I do?

If you have not cut them yet, DONT. Go to cartoys or ebay and look for adapters. If you have cut them then go to autozone dot com and make a free account and then logon and put in the year and make and model and then look at the free repair guides to see if the schematic wiring diagrams have the information on the stereo.

check the fuse behind the stereo and in your fuse box first off and make sure the power wire/ignition wires are on the correct pin. do this with a test light for verification. also check the ground wire. after you test and connect these 3 wires, the stereo should turn on. Your wiring harness may not be done correctly so visual verification with a test light would be the best thing before starting a car install. If this still does not work and the stereo you took out did, it is a malfunctioning unit.
put back the factory stereo if the car works then you have a model that depends on that head unite you will need to use a factory stereo by pass harness to solve this problem when you install you after market unite.this is a common issue with newer factory stereo's if putting back your factory stereo does not fix this then check all your fuse's generly there are more then one fuse box in newer cars
Yes there is an adapter. It will help you from getting a big headache. The wires will match from the stereo to the adapter and all that will have to be done is use an installation bracket. Plug and play. Trust me spend the approx. extra $40 dollars for the installlation kit and installation harness. Both can usually be bought at an autoparts store or even wal-mart.
I am currently undergoing this as well. There should be behind the instrument panel on the right side a harness for the old steroeo, but if it has been removed the hardwiring is pretty straight forward. My first step was finding which wires go where. Pull out the speakers and see what's there. That sould get at least eight of them out of the way. After that it was trial and error for me. I have a wriring diagram for my truck but there have been so many accessories over the years you can't tell what's what. Black should be ground. Yellow is Accy. power and Grey is constant power supply. Good Luck!
Red(is power, Orange(is led power Black(is ground Their should be a bunch of other wires with light colors that are your speakers. If this info don't match. Buy a power tester and ground it and test each wire.
