Head Unit Question

[yroc434]

Really there isn't expect that on decks with dedicated sub preamp's there is usually also a set of front, rear, and sub preamps and usually the sub will have several xover settings to choose from vs. a deck with switchable rear which is one in which the deck has two sets of full range outputs with the rear set being able to be set to one specific low pass point and handle the duties of the sub, also usually on these decks when the switchable preamp is engaged you also lose the fader..

so since im using the switchable preamp output is that a bad thing? what should i look for in HU when it comes to Voltage, outputs etc.?

There's nothing wrong with doing it this way, it just limits your flexibility when it comes down to a more complex install but is fine alternative if you are just getting started. As you progress to where you may want control of your front and rear speakers as well as a sub then you can look at getting a deck with front, rear and sub preamps or maybe a processor which most likely will already be setup that way. Most decks like that should be around 4-5 volts.....
