Bass not so great with Infinity BassLink X - bizzare problem?

[Jamie]

This weekend I fitted the Basslink - it all went well, seats out, controller cable down, fed through gromet behind rear drivers seat bolster - sorted.

Spliced into rear speakers, soon realised an e46 is not like an e36 where speakers can be unbolted and cables exposed. Ended up unbolting speakers from the shelf and splicing into the cables there...

Right - question number 1 - the colour coding on the speakers are not intuitive in suggesting whats + and - and so i MAY have got the polarity incorrect. Could some tell me what is what with these colours?

OK - so cables spliced, i plug the connecters in, power it up and i get bass - cool. Operation put the car back together

OK - so, fitting has to be completed, but i thought id go ahead and tune the thing.

Followed the book and instant reactions was - humm, this is rubbish! [bang

I fiddled with the crossover/gain/ etc etc - but nothing helped. I had to turn the volume up pretty high to get any real action out of the box - as if the thing wudnt work unless a decent amount of power was going in..

I left it at that and decided id post on here for help

Anyhow - during the drive back from derbyshire to london, i fiddled with the fader/balance on the headunit (i only have the standard headunit)

WOW - i moved the balance 1 notch to the LEFT (usually dead middle) and it was like sumone had kicked the basslink into action - BOOM! Sounded LOADS better. But i thought- this cant be right. One more notch to the left and it sounded better - the more i went the better it got but eventually was too much

If i move the balance 1 notch to the right, its almost as if the basslink is switched off. Moving it more and more to the right, its become quieter and quieter

The standard speakers work fine and always have done

So - what have i done wrong? Is it maybe due to polarity? Did i my fluke get it right on the RIGHT hand side, but wrong on the LEFT?

Could the basslink be duff?

Help/advise appriciated !

Thanks!!

to me sounds like you spliced into the left speaker so therefore only get bass out of the left channel. So its really only getting half the power it should be when the fader is in the middle.

Narr - trust me, I definitly spliced into both speakers - just unsure on positive and negative due to BMW speaker wiring colour (plus i have no multimeter!)

the polarity definatly seems wrong so double check the connections and make sure you have them the same on both sides.

also change the phase switch on the bass link to 180 and see if the problem is reversed, ie the bass gets louder when you fade to the right. if it does then you have the phasing the wrong way.

Yup - just been out to check and indeed the polarity was the problem. The left hand side splice into the left speaker had been wired the wrong way around. Since i learnt brown is always negative, i fixed it!

Sound is like - SOOOOOOOOOOOOO much better!

Basslink ROCKS!

nice one [ok.
