There are lots of threads here discussing the installation of Metra or Scosche kits for aftermarket radio. I'm sure you can find them by a little searching/browsing.
Shortly: the main problem is the Taurus radio is divided in two parts of which the amp and radio (RCU
) is in the trunk, display with buttons plus CD or cassette mechanism in dash. An aftermarket radio requires more wiring work than typically, that's why it tends to be more expensive.
Adding an amp plus sub is easy and safe if you know what you are doing. You only need to run power wires for the new amp and if the amp does not have high level inputs, you need a relatively cheap adapter that drops the speaker level to line level.
If you are after good sound quality, here's what I would do:
- replace all the factory speakers with two way systems, either component or integrated
- add a 4-channel amp for the new speakers. The factory radio only has 4x6W but it is otherwise decent (unless you want more bling
- add a separate amp + sub. The sub amp needs to have proper adjustable low pass filter for tuning the bass response. It does not hurt if the 4-channel amp has adjustable high pass filters to match the sub low pass.
- if you are really into tweaking the sound, add a parametric EQ or use amps that have those built in.
