Although the Crutchfield harness adapters make life easier, I would go with a complete new install, that way you can use more power. You really want to use better gauge wiring, higher power amps (15W is lame for a sub). PLUS, what few people realize, the OEM radios decrease bass with an increase in volume (to protect the speakers, I guess). If you get a DIN after- market unit from Crutchfield, you will see a major difference. I have a 2000 Taco with an after-market deck connected line-level to two amps under each seat, after-market component 5.25" speakers in doors, and a non-powered Bazooka behind the driver's seat. So I know thereof what I speak...it kicks butt! So bottom line, IMHO, is to convert to after-market with Crutchfield. Won't cost you your first-born and you can't beat Crutchfield's tech support (no,I don't work for them). Good luck
