Fitting Pioneer powered sub to Coupe

[b3robo]

Hi guys

I've just bought myself a new CD player, a cheapo no frills Wharfedale ICS171 unit with bluetooth and aux-in to replace a geriatric Blaupunkt cassette unit that was in the car when I bought it. I was wondering how to go about wiring up my sub to this stereo and which components I would need and how to wire them

I've never attempted this before so i've read a few guides which tell me slightly different things.

I believe I need the following things

Fused power cable at 30 amps
Ground cable
RCA speaker cables
Line-out Converter (?)

This is my sub, the good old TS-WX20LPA
http://www.pioneer.eu/uk/products/25...LPA/specs.html



The back of my stereo has ISO connection and four phono connectors only, and a small white cable that I don't know the use for, here is one image I could find of the stereo:





I got this stereo cheapo with no instruction manual, I know very little about ICE and wiring except from what I can read in howto guides.

How exactly would the line-out converter be wired? Looking at the pics now it looks like I coudl wire it directly from the head unit to the back of the sub using those phono inputs, but I imagine i'd still need the line converter inbetween? also would it make a difference to the sound if I wire it from the L or R phono outputs from the stereo?

Also the stereo doesn't seem to be wired to the ignition in any way, this doesn't bother me too much but if I were to wire up my sub would it drain the battery? in which case how would I go about wiring it up through the ignition?

Any help would be appreciated

If you use the rca's on the back of the headunit (check if one's an input or not) and run an rca straight back to the sub.

Then have a look at the wires for the speakers/power and normally there is a blue or blue/white wire thats the wire that switches the sub on/off. Just run a wire back to the sub for that then its just the usual +/-

So would a line converter still need to be used on the RCA cables?

Your going to have to read the manual and see if the rca input on the sub is expecting a sub only input or can handle a full frequency range input.

This is because that head unit RCA output is full range only not a dedicated sub output like most stereos would have

If not you have to use the SP input and send it the speaker inputs from the headunit, not hard, my car came with a similar pioneer sub with the same setup before I binned it for being not to my standards

OK what I can see on the manual is the following:
INPUT LEVEL (at gain max)
RCA 100mV+100mV/20k
SPEAKER LINE 2.0V+2.0V/5K

From the website:

Built-in variable LPF (50-125 Hz, -12dB/oct.) Yes

Input gain control / phase switch Yes

RCA/speaker level inputs Yes

On the back I have the following controls

Frequency
Gain
Phase Switch
BFC

Where's an audio specialist when you need one...

One post above your last!!

Where have you got a line level idea from? google I bet. As your stereo has rca outputs you wouldn't use a line converter. they are usually used for stereos that don't have an rca output

I need to check the manual for the sub, i'll do it at work to see if the lpf ( low pass filter ) applies to the RCA in on the sub

[Jamo]

Looking at the manual the lpf filter is for all inputs so you use the RCA from FR and FL to the sub and the use the lpf to filter the frequency

Your only problem will be the blue wire to turn the sub on, if your stereo hasn't got a amp on output you may have to wire it to a 12v ignition source.

Ok good stuff, will give it a shot, thanks for the input amigos
