amp question

[xxxic3xxx]

its not for me but i have fitted dozens of speakers , amps, subs and what nots to my friends cars recently i just spend 9 hours sorting a full install for a m8 and STUPIDLY took his head unit for granted to have RCA inputs and it didnt , so without my knowledge he went and paid £20 for a wire with rca on it and the guy said just spade it onto the existing wires :| i thorght this was well dodgy, any hoo it never worked.

what i want to know is how to tell if an amp is fooked/blown/broken b4 he goes and gets another head unit bcus in my opinion hes clueless and borght a pievce of crap lol buh never the less im gona try n do it

what was it that he bought? was it a high level to rca adaptor?

he did connect it to the speaker wires and not the power wires

he had 6x9s in and he just cut them and spaded the extra wire in with it ill draw a diagram lol, but all the wire is was 4 wires and an earth at the end of 2 wires it was the red and the other 2 was the white... u no wot i mean?

see if the amp light comes on and no fault light.

then you need to stick an audio signal into it.

use a lead like this and an mp3 player

thanxs ive actually got one and ill give it a go and no there is no power to the amp,,, its all wired up properly except i didnt think that the remote was "that" important obv it is as ive not found ourt that the remote is when it tells the amp to turn on am i right in thinking this,,, if there is no light and its coneccted to the batery is this a dead fuse of a duff amp ... it was working a month or so ago

a little link from the +12v to the remote terminal will turn the amp on
