Small Fader + Volume Control for car

[seanuleh]

Okay guys, massive noob here so bear with me, trying to understand everything as best I can, not even sure if this is the right forum or if it should go in the car section but I _THINK_ this is the right place :F

Basically I wanna hook a tablet into my dash to replace my head unit but it will take up all the available space. I'll be running a DAC DESTROYER that i got off ebay as a USB DAC running to my 5ch amp. Since the tablet will be permanently mounted into the dash I won't have any decent access to the volume control. Also, the output will obviously only be two channels. I'm pretty sure that's okay though, I think its safe to just bridge the RCA's at the amp to power the rears and sub, not too certain if this is okay when you start talking impedance but from what I gather, that's more important on the amp's output? :F

Anyway, the question is, I really don't want to lose a physical volume knob and I want to keep some fader control because my rear speakers are pretty terrible and don't want them kicking as hard as the fronts. I know I can control this at the amp and I _THINK_ with the usb dac I will still have volume control from the tablet, but that's a bit shitty. Having a proper volume control that's accessible instantly seems pretty important. The only place I can think of mounting knobs on the centre console now will be in the ash tray.

bit small, but if you look closely you can see the spot im talking about is next to the cigarette lighter socket which I want to keep so I can't just hack in a half-din eq.

Is there any solution to this? I'm competent in electronics (just don't know much about audio) so if there's a diy solution i wouldn't be too afraid of attempting that. Pretty much want to go from USB DAC [2ch rca] -> Volume/Fader [4ch(or 5ch) rca] -> amp with a small footprint on the volume/fader.

Any help would be greatly appreciated!

There's some stuff on Ebay that does volume and/or fader with RCA sockets. I think you'd get better help if you posted this in the car section. It's not a digital line level - it seems to be analogue line level.

you're right champ, posting this in analogue line level now! my bad
