Ok, today i installed my headunit amp and sub. the headunit works fine but then i dont hear anything from the amp. i have my wires goin from the headunit to the amp and wires from the amp to the sub. i grounded the amp as well. but i still dont seem to hear anything from my sub.

headunit - jvc el khameleon
amp - sony 222w
sub - pioneer

if anyone could help, i would b appreciated

 

does the amp come on after u turn the radio on?

 

how would i know if the amp is on?

<noob in stereos

 

on most amps there is led's (bulbs) that indicate power/protection, basicaly a check system they should also be labled as to what bulb is lit power is usually red and protection is green

 

ok, i checked if the power/protection light was lit. it was not. i have a wire from the 12volt positive goin to the headunit 12 volt ignition wire.

what could be wrong?

 

Power should come from your battery.

 

i dont get this ****, ill take a look at it again tomorrow

 

make sure u dont have n e wires crossed and a good ground

 

maybe you should mess with your amp settings

 

did u hook up them up to the right rca out put

The BATT terminal, or +12V as it might be listed, should connect to your battery. You should put a fuse inline no farther than a foot from your battery just incase something should go wrong. The REMOTE line you run to either your radio's REM OUT, P. Antenna, or your radio's accessory wire.

 

i dont think it will be my battery, im thinking it is my wiring. i checked if all the positive and negative wires were all right goin to the pos/neg spots. they were good.

i also grounded my amp to the seat railing bolt that holds the seat down to the floor (has amp under seat).

about the right rca output, i dunno what that is

rem out. i dont have that connected to anything. is that bad? i dont know what to do with that one.

 

was there a spark when you plugged the power wire into the amp? if so, you didnt disconnect the power terminal from the battery and you blew your fuse. check the fuse, thats most likely your problem

 

i didnt see the spark bcuz i disconnected the battery terminal. but i have not checked the fuse yet.

 

anyone?

 

i work at a stereo shop. heres what you do... leave the non-connection to your battery like it is. hook that lead to your amp. make sure when you run the power wire (the wire we are talking about) to your battery, run that wire on one side of the car with your rem. turn on lead. the rem. turn on lead on your deck should be blue. make sure your ground is as short as possible. then run your rca cables down the other side of the car. you want those things as far apart from the power cables as you can get. to plug the rca's in there should be some plugs on the back of your deck that are red and white. depending on what deck you have, there could be more then one set/pair. choose the pair that say rear or sub. run those like i said then plug them into the imput on the amp. it should say imput or out put. the ends will match color for color. now all you have to do is plug the sub in and tune the amp. i don't know the specs on the amp or the sub so i couldn't tell you how to wire it properly but, give it a try by just running the poss. and neg. directly to the amp. don't worry about bridging. if you tell me the specs on the amp, i can tell you how to properly wire it. i have to know how many channels the amp has and what ohm the sub is. if it has dual voice coils or not. im just gettin ya runnin. see if you get sound by following what i said. good luck dude!

 

thanks for this info. ill try to check over everything tomorrow and tell you wsup, thank

This sounds like your problem.
You NEED RCA going to the amp.
The HU needs to send a signal to the amp.
and set the gain on the amp.

 

ok, here is something people over look, make sure the remote turn on wire is connected to the amp, and make sure its the right one. usually its baby blue or blue. and to know if ur amps on, there should be some light of some sort to tell you, if not, u gota shitty amp and goodluck . but try it out!!!

 

someone needs to drawl out a diagram for this guy

 

I tried, but I have a feeling I left something out, someone let me know.

 

looks good to me

 

thanks for all your help, all i really needed to do was hook up my rem wire to the blue wire.

the diagram did help me and the response before that i believe that was talkin about the REM wire helped me also. thanks a bunch

yeah its just the "blue" wire...it took me like an entire weekend to figure that out when i first installed my amp
