i keep seeing all these line drivers for sale, my brother in law bought one cuz the guy at the local shop said it would help him get rid of some alternator whine. i think it's bullshit, if anything it should make the whine worse, by theory at least. hes changed the grounds, he's using the same ground for the subs and mids/highs, 2 different amps, but he's only picking up the alternator whine on the high end. only other thing i could think of is that the shop thats recommending the line driver installed his shit, they ran the rca's,remote and power altogether. i think thats where the whine is coming from just from a past experience. any other suggestions?
another thing, when you run a line driver, like the one he bought it says 8v rms, does that add to the existing voltage or is that the flat output like an amplifier? for example, i have 5v preouts on my hu, if i used an 8v line driver, would i have 13v or 8v? i been trying to read up on benefits of line drivers and i cant really find any unless you have a shitty head unit with low voltage rca's, if anyone has any links to information about line drivers i'd love to read up on them. thanks in advance.
