Sub install PROBLEM

[AhmedRSi]

Just installed a sub bought from a member on here but it doesnt seem to be working, ie.. not powering on. Feeling gutted atm spent 3 hours making sure all the wiring looked nice and tidy then to find it doesnt work!

Used an ampmeter to check that the sub is recieving power... and it is but its not working.

Could it be a broken sub? what should i check?

Things to check.

1) Earthing - often this is a probelm as the earting isnt very good(for amp) and sub wont run.
2)Remote cable - Is plugged into the right place on the H/U

Go and check these two as there is a good chance this will be the probelm.

Wiring was fine.

Turns out it was the fuse on the sub! One new fuse later its happily blasting away!

Cheers for the help

Nice one mate. Enjoy.

Is it an active enclosure you are using?

 

[AhmedRSi]

yes it is an active enclosure.

New problem - Just done a 3 hour journey... towards the end i noticed the sub is not always working! every 4/5 minutes it will appear to turn off randomly halfway through a track then come back after 30seconds or so. What could this be down to? I doubt there is any loose wiring

I'd check the earth to be honest,

I use to have problems like that ages ago!

 

[AhmedRSi]

Earths fine. Drilled a hole in the boot and used a self taping screw. its just grounded to the chassis

 

[Hazza]

Might be the amp overheating. Make sure that there is gaps for the amp to 'breathe' in a way. For it to cool down.

try a different earth point and check the remote connection is good. might be a loose connection

 

[Fred@BTM]

is the sub "banging innit"?

 

[Dcds4]

mon it bangin not dis banging

 

[AhmedRSi]

Might be the amp overheating. Make sure that there is gaps for the amp to 'breathe' in a way. For it to cool down.

Its an active sub, the amps built into the box and yes theres room for air flow.

try a different earth point and check the remote connection is good. might be a loose connection

What would you recommend as a good earthing point in / around the boot area? Cheers

 

[Ruffneck]

Make sure you scrape the paint away to bare metal on your earthing point, and make sure it is secured VERY VERY tightly.

Earthed mine under the rear seats. Will get a pic later if you want...

 

[RM_bailey]

Yeah earthed mine under the rear seats behind the passenger seat, seams to be the best place to earth the amp, make sure the remote wire is connected properly behind the head unit aswell becuse my dodgy conection was the problem with mine.

mine on the rear seat belt bolt

 

[AhmedRSi]

Earthed mine under the rear seats. Will get a pic later if you want...

A pic would help, cheers. It doesnt do it anymore, I think only when it was on for 2/3 hours straight... maybe it was overheating

I've used the isofix bolts in all of the 3 i've had and never had a problem.
