I was recently given a 10" solo baric sub and a rockford fosgate 250.2 amp i want to use them without changing out the factory head unit. Any insight into what i need to do this?
my friend tried to do this... what you have to do is split the speaker wire that runs to your back speakers using some sort of converter which produces an rca output so you can run it to your amp. i dont remember what the converter is called, but if you call best buy or some professional installation place they will tell you.
the problem with doing this is the sound quality is really bad. its pretty much not worth it. my friend eventually got a new head unit after a couple of months
The converters are called Line Output Converters (LOC) or Hi/Low converters. The best budget ones are probably the ones by PAC, however if you want better sound quality without changing the stock head unit, get something like the AudioControl LC6i.
Usually, the bad sound that often comes from a setup like that is not due to the LOC, but to the HU (a lot of factory HUs suck big time). Ever heard the saying "garbage in = garbage out"?
