I used all Stinger RCA plugs and wiring. I spend the extra cash to get the Expert series RCAs. I used 4 guage power wire for the main line and to both amps and 16 guage for the speakers from the amp to the harness. I will use 12 guage for the subs. I did not want to splice into any wires but I did not have a choice with the radio. When you get the JBL system, the wire harness for the radio does not work where the radio resides. Instead, you can plug the harness at the rear where the facory amp plugs are at. You have to cut the ends of the harness as shown to allow the harness to plug into the factory plug. I coud have run all new wire to all the doors but the factory wire is good enough to power all my speakers. Also saves alot of work and keeps things neat. I also used a Stinger 1 Farad capacitor which I placed under the amps in the facory storage compartment area. If you own a Tacoma, you know how limited the space is for any sound components. I wanted to show the capacitor but there was no room anywhere. That is why I had to bury it under the amps. After all the wiring was routed I made an amp rack out of plywood to mount the amps in. I then covered it in black carpet to keep things looking clean. Because of the limited space, I decided to use the new PDX series amps. I used the PDX 1000.1 for the subs and the PDX 150.4 for the MB Quart components. I also used the MTX RT-X02A crossover to fine tune it. The bass boost button on this crossover makes a HUGE difference in sound. I could have just left things alone after hooking up the amps on the amp rack. After all, the seats will cover them anyways. That would be too easy! I decided to make a fiberglass cover for the amp rack to give it an extra touch. One more full day of work just to make it different. Here us the amp rack and cover finished. I used grey carpet to match the factory carpet. Also notice the fused distribution block I used. It is a Stinger with blue LED amperage and voltage display.
