behind the stock speaker?

[nd240sx3]

what the hell is that crap behind the stock speaker that looks like curcuitry in electrontcs, whats it do? is it like a miny amp or something? should i still use it when puttin in new speakers? or no. i never seen anything like that before

[Wei240]

you mean for the front? (i think the rear has one too)
yes, they are crappy 15w amps (i think), most stereos/radios/speakers these days are much more powerful, so you don't need those

if you use the stock head unit, you need to use those amps (i think) if you put in a new headunit you have to remove the amps and rewire the speakers. check the FAQ section for a write up.
