Has anyone fitted a subwoofer with a standard radio. Thinking about doing it to my focus. It's a diesel so I'm not sure about wiring power as sometimes you can get interference. My old fiesta I had an aftermarket headunit and amps ect ect but I've never fitted sub with standard radio. My radio is a ford 6000cd. My car is a zetec model and it's 2010 if that helps as I think there are a couple of variations of the radio?

Many thanks

Its do-able - i think the CD6000 has line- outs and even if it did'nt, you can tap into the hi-level (speaker) outs via an adaptor

Diesels are less liable to get interference (no ht leads etc) and often have beefed-up alternators and bigger batteries (more electrical power), sp are generally better for high-power ICE

The safest and best way to take the main power (+) off the battery via a high-amp inline fuse with heavy-duty cable to the amp,which is constantly on. The amp usually has a "signal power line" that switches the power on/off, via the head unit

the anp gets earthed to the good ground (thick, heavy-duty cable)

The audio output of the head unit is connected to the audio input of the sub amp via a screened audio cable, normally very long, so it can be routed/ tucked away out of sight

Something like this you may need....

i've used this from halfords to connect my sony oem unit:

wired up my Vibe Sub/Amp combo and its fine.

I'm getting mine done by AudioWise, Eastkilbride.

They said they can do it with the normal head unit but it's usually not AS GOOD as with a third party unit (but since mines is the new model, they can't really change it yet!)

but he said what they can do is use a (don't quote me on this) High line convertor (there are different ones, but they use a £35 one) depending on the quality of that, it can affect the quality of the output.

If I remember, I'll report back on monday/tuesday after I've gotten it all installed :)
