Hi,

I took out my ICE from my old car and now have it sitting in my garage, so I’m sort of thinking of sticking in the Fabia. My question is thought if I only take one RCA and feed that into the low pass of my amp that will run the sub fine but what about the standard door speakers. As I can't be bothered to run new wires to the door speakers with a high pass will they also have a load of base going through them?

I know it's a weird way of doing it but I’m looking for the easy option to start with.

Cheers
Ed

Awol

I might be being thick but what has installing just a sub got to do with your standard door speakers?

if your taking RCA's out and only wiring the sub on them then your standard speakers will be exactly how they are now?

That’s sort of what I’m talking about; will the standard speakers stay the same? If they do stay the same then when I turn up the volume then the standard speakers will get hit by the base and kill the sound. I THINK if I use the headunit's EQ then it affects the output to the RCA meaning I can't cut bass that way?

So I guess the question is how can I cut any bass from coming out of the standard speakers and get them to act just as components?

You could wire capacitors into the speaker wire, don't ask what ones though as I'm unsure.


It can be done I'm just not sure how .........lol

Go buy a high pass filter for the rear speakers.

It's basically cap so will filter out the low frequency.

F-MODS In-line crossovers at Crutchfield.com

You would need to find a UK supplier of them or build your own circuit out of caps and a resistor.

Just run the sub it will be fine

the ICE should have a pre out which looks like cd lead sockets, run this to the same at the amp and on the amp look for low pass or sub. as its a sub you may have the option of bridging one + or - on the left with the opporsite on the right this then makes the amp 1. mono and 2 maximuim power (if the amp supports bridging). this will have no different effects on the cars present speakers in any kind of way. however run the sound lead down one side of the car and the power leads down the other to avoid interference.

as above i think, just wire in the sub as you'd expect let the amp filter it. it woudl be fine with normal headunit settings i'd think. most people who just buy a sub just leave other speakers alone.

i'm pretty sure the point of the RCA out is that is a clean output, not effected by how you change the bass etc on headunit? then it leaves all the filtering up to the amp?

unless your headunit has a specific sub rca out?

Cheers guys!

The idea of having to install capacitors into the cable is interesting, if i remember correctly i had some components with a similar setup to that between the mids and highs.

Think i'm just going to plonk it in and see how we go, sounds like i should be ok. Never know by the time i have all the trim up doing that i might end up just doing it all.

Cheers

Awol

yes and good components will have a filter

I was just thinking of filtering the bass from the rear speakers so it doesn't get muddy as I am guessing they will vent into the boot where the sub is.
