Amp earth in boot????

[smithygcupra]

santa give me a nice sub and amp for xmas..... linked it all up..... but the sub fades if turned up too loud ( which isnt verymuch) ..... ive come to the conclusion that its a bad earth... anyone got advice on the best place to earth??? any advice/ pics much appreciated

i used the mounting bolts for the rear seat belts. you may need to use a file or similar to remove the paint in the area first.

thnx man... will give it a bash.... has anyone else had the same problem with the sub fading in and out when turned up?? or anything similar??? its been really winding me up....

What size power cable are you using and where are you takin power from? Oh yeah which amp?

 

[kegger]

I used a bolt behind the back panel, just by taking off the light panels first... it doesn't matter really where you bolt it so long as you've got a clean connection with no paint obstruction and its to a structural metal panel if possible.

hi just a quick question where did you get thew power cable through at the front of the car?(from engine bay to interior.
cheers

I have installed a 1F capacitor between the battery and amp.

It is used to smooth out the power delivery to the amp.

Take your pollen filter and glovebox out and you will see a large grommet - feed the cable through here. the glovebox is only around 8 torx bolts, and the pollen filter is 2 screws. If you disconnect the airbag switch when removing your glovebox, do not turn on your ignition before you plug it back in as it will put the airbag light on on your dash. good luck

Sorry Danny but no, if you fiddle with you pollen filter too much you get the wet feet effect!!

But your dead right about airbag switch!!!!

i didnt feed mine through there.... didnt want to mess with all that tbh..... i fed the cable through a gap in the wing and it came out by the passenger door....then fed it through into the car behind the hinge andit comes out directly in the passenger footwell under the glovebox... then fed it through to the boot...... you cant really see te cable by the door hinge unless your looking for it to be honest....

that link isn't working? i used bathroom sealant around the grommet after feeding wires through it. I've had wet feet before due to not fitted the pollen filter cover properly after meddling, lesson learnt, but i'd be interested to know of another grommet to use.

Fixed the link Danny, i used pollen filter route on my old LCR but found this route on ivecaverns forum, I cant take credit but i can use the idea and pass it on!

cheers for that pete, next time i route cables this will be very helpful
