hey guys, is it possible to add a amp to a factory HU? if so is it worth doing? or should i get an all new HU? any opinions will be greatly appreciated.

thanks

 

dooable - yes
worth it - your opinon (sound quality is okay for subs, not made to enhance door speakers)
if you can afford a new hu - go for it, but go for quality then, you might as well get the best bang for your buck

to hookup a amp to an hu w/o rca outputs, you'll need 1 of two things

either a line level converter (available at walmart or any stereo shop) - it taps off the regular speakers (1 pair) to make 1 pair of rca level outputs - - so so quality sound

or get an amp that accepts high level inputs - much more stable, usually no adjusment neccesary and the sound quality is better than the above method

good luck!

 

You will most likely need what crayonBOX said a level line conveter or a High/Low End Converter to do this.. Can be done I did it to my factory H/U in my celica but honestly I think you should go with an upgraded H/U you'll get better sound quality..
