Is this for using a factory headunit with an aftermarket amplifier? Or am I completely off base?

My headunit has 3 pairs of rca output - Front, Rear and Subs. I have 3 amps

1 - Blue Thunder PRO150X2
2 - Blue Thudner PRO150X2
3 - Alpine 75X4 4 channel

The Blue Thunder amps are each bridged to thier own sub, the 4ch runs my highs.

With a line driver I can take the 4v(peak) signal for the subs that I am currently splitting 2v(peak) to each sub amp and drive it all the way up to 13.4v(peak) for each amp.

You are comparing apples to oranges, sorta like me saying "look I am taller than michael jordan when I stand on my tippy toes and stretch my arms over my head"

7.5 is peak output, the rms on this is 9.5V, peak is 13.4V.

How is it apple to oranges? Both put out a signal that the amp reads. The signal line driver is just higher. And no your example is sh!tty.

They are 2 different ways of measuring voltage.

Duh. I just stated what my head unit puts out. And by the way its 7.5v RMS not peak. Again both put out a signal that the amp reads. The signal from your equipment is just higher.

You have to get out of the "everything is inferior to what i own" mentality.

I fairly certain he was just clarifying, no need to start a cat fight.

Nice unit JP7, I wouldn't mind that for my AVIC.

nice unit!! keep in mind if the amps your feeding is not rated for that kind of input power they could run hot quickley. honestly anything over 10 volts input is a little over kill. but run it wide open if it makes you happy. just keep a check on yout temps.

and what unit are you running? last i knew 5v was the highest. you dont need anymore that that unless you split signal more the 4 times. 2 times you dont need. watch ur amps like stated. most dont like to see over 6v. and hope you have NICE rcas or else this is a waste. i will spend more damn money on rcas that any other wiring.

I've never seen one of those before. I bet it would dramatically improve my amp's output.. My fairly cheap headunit unly puts out 2v (peak I think!) and I have to keep the gain on the amp at like 3/4

The output of the head unit is differential, not single ended!

my previous headunit was an 8volt.. eclipse cd8443. best built headunits period. that was a few years ago though.. i dont know if the company is any good anymore since it's been bought and moved around so much
