basically ive got the power, and the remote lead sorted and the rca cables from my headunit. im getting power to my amp when i switch my headunit on, where do i connect the sub to ? and will it not be working because i havent got the ground lead in ?

stumped here about to cry like.

thought id at least be able to do it but i cant!

cheers for any help at all

you'll have connector points on the amp iirc the MF400 its gold bits. + and - on your sub sorted

[Oranoco]

You will need the ground lead connected to the cars chassis somewhere or you won't get anything as the circuit ios incomplete.

The sub will connect to the speaker terminals on the amp but you will need find out if the amp you have got has a low pass filter on it (filters all the mid and treble leaving just the bass frequencies) and wheteher the amp will run in bridged mode to give one more powerfull channel.

thank you very much people, will any old wire do to make a ground ? or does it have to be a specific sort ?

[madsekci]

I do tend to believe it's a more special wire like the one that powers the amp. I know mine are quite large in diameter.

Speaker wire is speaker wire...you must use the same AWG wire for ground as you do for power IIRC

[xr2i_gash]

can you buy the ground wire separate from the rest ? and where is the best place to ground it to ?

sorry about all the stupid questions just this is my first time of doing it and ive tried searching for my problem and cant find anything.

i asked a feller in the car electrics shop round ours and he said he'll do it for 28 pound an hour, but theres nowt sayin he'll take 10 hours to do it and charge me for other s**t as well !

[diablosvy]

£28 haha thats rediculous took me about 2 hours on my own. As said speaker wire is speaker wire im guessing your power wire is 4AWG then you need 4AWG ground wire...when you buy it in a pack its usually covered in brown plastic to signify its the earth, but that dusnt really matter if youv only got a simple system. I would go the ebay route personally or an electrical store, or car audio shop...halfrauds didnt have any spare when I went...
You will need to ground it to the car chasis, theres some in the boot near the bootlid, just scratch away the paint until you can get bare metal then put a bolt through it.

p.s. it needs to be as short as possible so I wouldnt go any longer than a metre for the earth

[xr2i_gash]

well first go at it, bought a new lot of wires , got the earth wire in, nothing, theres obviously something im missing.
ive got the remote, power from the battery, and the earth wire in, the amp switches on when i put my h/u on, but im still not getting anything from the sub, ready just to bin it, and be a saddo and get some 6x9's and a stealth shelf, at least that way im getting a bit bass.


or put it in the shop the morra and get them rip-offs to do it.

none of my mates know anything about this s**t so im sort of stumped.

Is the amp powering up? If it is what colour is the light (green or red) if red then you probably havnt got a decent earth, thats the only reason I can think of, other than the sub being nackered.

Mike

[xr2i_gash]

the lights green, but.................. it lights up off just the remote wire, even if ts not connected to the battery, like thats powering it, ive tried changing the fuse in the amp and allsorts just to see, but nowt.

[Oranoco]

Where abouts are you mate? If you're not to many miles away I may be able to pop over and help out

[xr2i_gash]

cheers people for all your help, i bit the bullet paid 30 pound, the feller in the shop only had to move one wire, i needed the sub to be on both positives on the amp.

i left my car with him and he rang me about nine minutes later.

gammon slipper !!
