I just installed a set of Infinity Kappa 5.25" components in the rear panels (didn't put in tweeters yet). Speakers are connected to a crossover, which is directly connected to the rear speaker wire harness in the knee panel. Speakers are powered by a Pioneer HU using the harness wires (as opposed to RCA rear outputs).

Problem is: I notice that the rears seem a bit weaker than the OEM fronts and, at high volumes, don't sound as clear and are sometimes raspy. I'm pretty sure my connections are fine, and although I'm just using typical 18 gauge speaker wire, I didn't think it would be a problem.

What are some possible things I could check, or possible reasons for this?


Also, on a side note, one of my wires on my tweeter snapped off, leaving almost no wire left on the tweeter to resolder the connection? how would one go about repairing this?


Thanks.

 

pics of the tweeter?

As far as the speakers, maybe you connected the polarity wrong, assuming your stereo settings are not faded forward any...

 

Here's a pic. As you can see, what's left of the red wire is almost down to the very bottom.. might have to try getting as much wire out of what's left as possible.. and soldering a new wire on? Black wire is almost about to snap off too



As far as the speakers, the polarity seems to be correct. I connected it as such:

Driver panel Blue > Crossover IN+
Driver panel Gray > Crossover IN-
Crossover WF+ > speaker +
Crossover WF- > speaker -

There's also another set of lugs on the speaker that I didn't use, but it says "Not to be used with components".

What else could be wrong? The fade settings are fine.. just seems like the rears are a lot weaker than the fronts at the same volume level.

 

This is solder, and underneath it you will probably find a metal tab with a hole in the middle of it. You can solder a new wire directly to this; same for the other tab if you want to clean the tweeter up a bit. It may help if you use a desoldering iron (or my favorite, desoldering braid) to remove the old solder and wire before you attach new stuff.

The Kappas have a lower efficiency rating than the OEM fronts, because they are designed to be used with higher power than a deck only (they are usually amped). This is likely the reason they are quieter.

 

K I'll give it a shot. I've had exp using solder, but never de-soldering.. but it's worth a shot

Another slight "problem" with the Kappas that I've noticed, it sounds slightly raspy at high volumes. Is this also because it's not amped?

Thanks.
