Adding an amplifier to factory headunit (did search)

[Jodienda]

Hello everyone,

I did a search on the forums and couldn't find the exact answer I needed. I noticed that most people who add aftermarket amplifiers to the factory head unit are using line level converters and splicing into the factory speaker wires. I wanted to take a different approach and not cut into any of the factory wiring in my Yaris. I found this and was wondering it it would work in the 2007 yaris hatchback: http://www.scosche.com/scosche_carau...8&ItemID=TA03B

I was watching diy network the other day and the guy installed an amp to a factory head unit by using two "pigtails" that actually fit into the factory head unit. He wired the line level converter to one of the pigtails, and then wired that pigtail another pigtail that was plugged into the head unit. Finally, he wired the factory harness into the pigtail end that wasn't connected to the head unit. Anyone know where to find these by chance?

Oh, I bought my car about a month and a half ago due to having a new job where I commute 100 miles a day. With less than 3000 miles on it, I'm getting a steady 38 miles/ gallon with 80% highway/20% city. I drive 70mph on the highway. It's a bayou blue HB 5 speed manual, with the power package (60/40 split seat, rear defroster, power windows/mirrors) and the all weather package. Unfortunately, my area didn't have any like that with the alloy wheels so i'm rockin' the steelies for now :(.


Thanks!
