First things first, the previous owner had cut in a DIN style radio and removed the old radio with the knobs...which isn't necessarily a problem....especially now that they make face plates to cover them up....though not as nice looking as if the knob cutouts were still there....but the faceplate matches perfectly with the existing dash in the truck.
The Hermosa radio gives you everything you'd need in a classic truck like this; Am, FM, (2) Aux Inputs, USB and Bluetooth. I installed the Bluetooth cable into the glove box without cutting any holes anywhere.
Next in line is the Quadraphonic 4x45 Amplifier that's got a nice hide-away design. Made some custom brackets to mount it behind the radio, up and out of the way and tuned it so the customers gets clear highs and mids at all volumes.
That powers the new 6.5" speakers in the kicks and the existing speakers in the dash....which when setup with a high-pass crossover filter, these work together as a quasi component system.
To fill in the bass, the 8" powered subwoofer fit under the bench seat without a single issue and provides plenty of bass in this single cabin area. There is a bass-knob I put under the key solenoid so that his keys will hide the fact that he's got bumps underneath until he turns it up.
Without going completely aftermarket with no budget, this Retrosounds package is exactly what music should sound like at the budget range you're in. Yes, it could sounds better....but it could definitely sound worse as well.
If you want really good sound and have it look like it came that way from the factory, then this is the route I'd suggest.
