Can anyone help me with my Hi fi?

I moved it somewhere and brought it back, but I think I did the wires all wrong or something.

It can only seem to make 1 bass tone.
It keeps crackling every now and then

Ok, so what speaker wires go where?

I have 4 sets of speaker cables so I can bi wire them.
I have two speakers.
Each speaker has 4 knobbly pluggy inny bits, top pair is labelled "HF" and the bottom pair "LF"
My amp has two pairs of + (red) and - (black) bits where the cable plugs in. There are two rows for each pair, A and B.

So it kind of looks like:

     R        L
    + -   + -
A1 o o   o o
B2 o o   o o

Where o is where the cable goes
The speaker cable has a + and - split.

So what bit goes where I'm all confused on this stuff!

I'm guessing the + side of the speaker cable goes into the + slot in the amp, and the - goes in the - slot of the amp.

I'm also guessing that I wire one cable into a(1) and one into a(2) and they both go to one speaker, but which pair of knobs does each one go to in the speaker?

Ok im really confused and annoyed at this crackling, any help appreciated! I' being really dumb!

Not really so up with Hi-Fi's but I work with PA systems almost everyday.

1st is don't use your system if you get the HF (mid/top) and LF (bass) the wrong way round. YOU COULD BLOW UP COMPONENTS IN YOUR SPEAKERS!!

I take it your amp has a built in active cross-over. If so you need to consult with your manual as to which output is HF and which is LF.

If it doesn't have a built in active cross-over and gives out a full range to all outputs then the cross-over maybe done passively inside your speakers so you don't need to worry about which wires go in the LF and HF on your speakers, but as your speakers have LF and HF inputs on them, it doesn't sound like they have a passive cross-over built in.

The best thing to do is have a look in the manual or check the manufactures web site if you don't have one.

Also make sure you wire the (+) and (-) round the right way on all your speakers, otherwise your speakers will be running 'out of phase' with each other and will cancel out frequencies reducing sound quality and the amount of db (sound level) produced by your speakers.

     R        L
    + -   + -
A1 o o   o o
B2 o o   o o

You must always connect one speaker lead to + - ie do not connect a speaker to -- or ++.

Ok From here R stands for Right side L stands for Left

A1 May be you front speakers and A2 May be the back set. You can always swop this round if not correct.

If the wire has no plug you need to push the wire end into a clip to connect. If this is the case you need to connect the striped wire to

+ and the other to -

You need to connect the Right speaker to A1 R + & -

You need to connect the Left speaker to A1 L + & -

The Back set

You need to connect the Right speaker to B2 R + & -

You need to connect the Left speaker to B2 L + & -

Hope this helps Wink
