As they say "necessity is the mother of invention". Without the money for a proper setup (they (The Man) overcharge us (consumers) in Australia) my dad and I got his old speakers and amp and wired up something that sound like the real deal.
This instructable requires some (not much) knowledge about wiring speakers (plugs and whatnot)
Step 1: Equipment and materials
Amp (nothing fancy)
2 main speakers (pick these up cheap from garage sales/ flea markets or family)
2 car speakers (I used a $20 set)
Speaker mounting for main speakers (optional)
Drill / screwdriver
Saw (regular or plasterboard type)
Step 2: Arrangements and connections
Step 3: Mount!
Step 4: Enjoy!!!
