Making Quality Factory Integration Easy
What do we need?
Adding a subwoofer.
Seems so simple, right? Get two speaker leads and plug them into a monobloc amp? Yes it was! For years this was the way to do it. Nowadays though we have to content with factory amplifiers and EQ curves that boost and cut to give the illusion of bass and power. It’s all smoke and mirrors though so when we try and use that signal we get muddy, clipping, distorted bass that sounds bad and is dangerous to the subwoofer. Or, due to high voltage, it can overload the input section of your amplifier or cheap line output converter, causing damage to the electronics. Or possibly even worse it works…at low volumes. But once we try to turn the volume up the factory amplifier overcompensates for the poor output potential it has and throttles the output of the lower frequency signal. Meaning no bass when we really need it! Noooooo!
Enter, actually half decent Line Output Converters. There are a couple of types. To handle high current applications and to deal with automatic bass roll off companies have developed and patented technologies that can handle the voltage and analyse the signal to bring back bass that was lacking automatically, relative to the volume set. It’s actually pretty incredible to see and hear it in action.
Fixing the Signal for a Sub or Full Range System
With a great premium factory sound system comes great and tedious problems when we go to upgrade. This is not the end of the story though. We can still work with this, using input processors made for cleaning up factory audio signals. With these boxes we can install and by either analogue pots or by a simple press of a button, we can cancel and clean things up like crossover settings, EQ settings and factory time alignment. Nothing is passed over and what remains on the output stages of these devices is a clean, flat signal response calibrated to give you the best sounding signal straight to your amplifier stage.
The benefits of doing this are two-fold. First the obvious, it’s going to sound better. If you have been reading along with some of the other pages about DSP’s and Speakers you know that the number 1 thing that needs to happen before great sound is a good clean audio source for your amplifiers to power. Without this it doesn’t matter how expensive your speakers are or whether your RCA’s are gold plated or silver tinsel woven. It’s not going to sound as good as it can, ever. The second reason is for signal reliability. You know that what you are getting to your aftermarket system is clean and flat. If something isn’t quite right you don’t have to look towards the factory system. That’s already fixed. And what’s better is that if that is the case then what is happening with the aftermarket system can be fixed as well. With a properly integrated system there’s no barrier to incredible sound.
