Head Units:

Some units have 2 volts, other units have 4 volts, some eclipses even go as far as 8, or 16 volts... Will i be able to tell the difference on these? Is it worth the extra money? (Not for the 16 volts, but the difference between 4 to 8 volts???)


I'm trying to decide between the new Alpine 9807 (3 sets of 4 volt)
Or an Eclipse (Don't know the model) with 3 sets of 8 volts.

Price difference is about $50

well some say the higher the voltage the more cleaner your music is, and some say if your gain is set correctly it wont matter

8 volts would usually leave you with a cleaner signal, but lotsa times your amps can't handle 8 volts. 4 is more than youll ever need for a daily driver

has to do with signal to noise ratio. If you have higher signal voltage then your noise floor will be lower. 4V is good enuff for 90% of the people out there.

I've got 8 volt pre-outs. My jl 300/4 has to be turned down on sensitivity, but the 1000/1 eats it up [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

I found my 2150x ok, but the JBL P80.4 is not listed anywhere on the website either.. it's probably 4 volts huh?
