How much of a difference do headunits make?


Recommended Posts

Compared to my stock headunit with a line out put converter, to one with say 4v preouts or even 2. How much of a difference would it make in speakers sound and subwoofer sound?

any time you convert a signal, you lose quality. Also, most decent head units out today have far more sound staging capabilities than something stock....such as time alignment, frequency band settings, and things like that.

as far as pre outs. Im not sure how powerful line out converters are, but the lower the pre out voltage, the harder the amp has to work.

It's not even about preouts at all. Your stock deck sucks internally comparred to some companies bottom of the line decks. Almost any aftermarket upgrade will offer a better cd player quality, better dc/dc converter, better signal to noise ratio, better tunner, better everything than a stock deck. This is a no brainer, just upgrade now!

A couple questions for you real quick.

1. Do you have upgraded mids/highs in the car?

2. Do you have the mids/highs on an amp?

3. Does your bass overpower your front stage?
