IAM sure this has been asked. Replacing center speaker 4x10 to a plate with 3.5s in the center. IAM thinking of putting four 3.5s in dash. two in the corners and two in the corners of dash. Wire them in series. Also getting 6x9s and brackets for rear. I found a website which repairs your stock radio. And does a conversion to output 45x 4 @ 4 ohms. I have a 1984 GMC with AC. Is the room to make this happen. Not really interested in kick panel speakers or cut up my mint doors. IAM sure not ideal setup. But would be a lot cleaner imo.
Planning on jbl. Gx302 in dash. And jbl GTO 6x9s in rear.
Any pics of center hole with AC truck for reference would be helpful. Love this site.
