Let’s Talk aftermarket Head Unit
To pair an aftermarket head unit with the premiere sound system found in my 2003 Volvo V40 I used the following parts:
*Autoleads PC9-414 Wiring Harness Adapter, $34 (dynamicsounds.co.uk) [+/- $50 w/ shipping from UK]
*Metra 70-9221 Radio Wiring Harness for Volvo 99-06, $13 (amazon)
*Metra 40-VL10 Volvo Antenna Adapter, $5 (amazon)
*Volvo Genuine Part – Box, 30613741, $26 (volvopartswebstore.com) [comes w/ rubber mat – no need to order separate mat like I did]
I then paired everything with the Pioneer DEH-6300UB, which has four pre-amp outs that I coupled with the PC9-414 adapter. Lots of instructions for wiring on google. To connect the 70-9221 harnesses to the Pioneer harness, I used insulated butt connectors and have had no problems (no soldering necessary).
**The blue wire from the PC9-414 adapter did not fit in the female port on the head unit. To power the amplifier and subwoofer, I spliced the blue wire from the adapter in with the power from the head unit. It probably would have been better to splice to the cigarette lighter, but I went with ease of access. If no power is supplied to amplifier, then the sound produced will no longer be ‘premiere.’
Any questions – let me know. This post is the product of many hours of research. It took quite a bit of time to make my dream a reality, but I can now play music from my iPhone through the car stereo! Cool thing about the Pioneer head unit – it lets you decide whether or not to control the music through the iPod/iPhone or the head unit.
