3 Pre Out Head Units
Hi, not sure if this is in the right part of the forum or not, but I'm after a car head unit with 3x RCA pre outs and a USB port. Ideally Pioneer, but.
3 Pre Out Head Units Replacement
If you want to upgrade your sound system in your car by adding a sub woofer or speakers powered by an auxiliary amplifier without having to get a new head unit then hopefully this should help you :)
I decided to keep my standard head unit because it looks well in the car, is less likely to attract thieves than a shiny after-market unit and it is a factory upgraded unit anyway and i find it gives pretty good audio quality, it works with the steering wheel controls and has bluetooth and aux-in, so an after-market unit wouldn't offer a substantial upgrade.
Factory head units rarely have RCA or 'Low line' outputs which your amplifier will need for it's input signal.
A 'Low line converter' is a device which will piggy back your speaker outputs from your head unit and convert them to Low Line RCA outputs for your amplifier
The converter i bought also gives you a 'remote wire' output which tells your Amp when the car is on so it doesn't drain your battery, if you get a converter without this option you can just join the remote wire to the Acc circuit of your car, or the 12V circuit with a switch (you will have to remember to turn it off though or your amp will drain your battery)
The methods i used will require an understanding of car/car stereo electrics so just be careful so as not to damage your car or yourself :)
