Fitted my 605cs yesterday thanks to BoostII and the FAQ, but have a question on the crossover. Currently I have the speakers connecting directly to my Kenwood headunit (no AMP) and was wondering if I should have the tweeter connected to the -3dB +ve output of the crossover or the standard non-reduced output??

If I set the headunit to zero levels for treble and bass I do get high frequencies quite hard, but if it's turned down to max they go away... Might not make any sense, bit hard to write down what you hear.

 

I have got some of those speakers myself. I found the treble harsh when at high volume levels. The -3dB connection does make a big difference. Try putting the treble to zero (my kenwood head unit goes from -4 to +4 on treble and bass settings) and start playing with the volume. I have mine set at -1 on the treble and +2 on the bass when at 20 on the volume. Hope this helps. Are you planning on running an amp at later date, you will find this makes a big difference aswell, as the head unit amp is not very powerful. You might get some distortion at high volume levels without an amp.
Infinity.

 

No mention of my help Ian Even if it was just a phone call

LOL - mines set up normal but I have my treble setting at -1 (bass at 0) and bass boost on 1 on my sony head unit.

Just about to ring halfords too

 

LOL - Jawa. I bet you thought I was going to call you back again Thanks M8

I've got the Kenwood setup like yourself Infinity, might have to take the door panel back off and change to the -3dB setting. I ended up making tweeter brackets out of the Meccano style bar you get with the headunits, so that I could mount them behind the door handle grill.

Thanks again

 

O/T - Called Halfords - Magnex were investigating, didn't call back Halfords on Friday so they chased them up today - Magnex aren't sure whats going on but will look into it and call Halfords back, they'll then call me. If I ain't heard by the end of today I shall call Magnex direct to get them to flippin well sort it.
