Hi all...

I have a 10-year-old Grand Prix with two 6x9 rear speakers which are bad. I
also have a nice pair of Jensen tri-axial 6x9 speakers (model J310TX) which
have been stored away for several years just waiting to be needed. I don't
know how old they are but probably from the '80s.

However the original Pontiac speakers have two coils and two sets of wiring,
one of which is for sub-woofer control, according to my service manual.

So what should I do about that extra wiring when I install the Jensens,
which have only one connector?

I am also concerned about the impedance. The ones in the car are marked
4-ohms, but the Jensens aren't marked and I can't find anything about them
on the internet. The only markings other that the name and model are "160
Watts Peak Power", "60 Watts Continuous Power" and "92db Sensitivity". If I
measure dc resistance I get around 35 ohms, if that's a clue

Thanks in advance for any advice.

PS: On closer inspection (by curling upside down in the trunk!) there are
two impedance ratings: 4-ohm and 10-ohm.

Hi
Probally the easiest thing to do is to find a set of the orginal
speakers at a junk yard, then it would be plug and play that simple.
But if your adventureous you can try hooking up a junk speaker to the
wires and see what they sound like. Since you say the speaker has 2
diffrent OHM ratings these are probally BI-amped speakers. The sub
wires are probally crossed over for LF and the others are HF. If your
any kind of an audiophile you probally won't be happy from the sound
from either set of wires as one set will be laking HF and the other
will be laking LF. IF this is how your system is set up you could
invest in another set of bi-ampable speakers but you'd probally be
cheaper to just go to the junk yard. But I'm guessing on how your
system is set up, I may be wrong. Hope this helps.

Regards,
Chance

Or hook the Jensons to the 'high' side, and hook the 'low' side to a sub
box....

These are dual coil speakers for having the proper response over the
frequency spectrum. You should get the originals if you want to have the
original sound quality. This way, you will be sure that the impedance match
is correct for the radio. Using an ohm meter will not show you the
impedance.

OK, I'll bite: what's a "sub box"?

Uh...a box with subwoofers (8" to 15" low frequency speakers)
inside...very common. You can put them in the trunk to produce the
'Whump!, Whump!' you often hear coming from the car in the next lane at
the stoplight...or you can actually install them where they'll reproduce
the low frequencies in a 'musical' way, if you have room.

In your case, the trunk is the easiest way, but not necessarily the
best. The crossover frequency is probably too high to get decent sound
through all the back seat padding and insulation. Perhaps there's room
in the rear deck for one dual-voicecoil woofer in between the two 6x9's,
but then you're getting beyond 'easy'or 'simple'.

My shop manual wiring color codes indicate the 10-ohm connections as "Audio
Input" and the
4-ohm connections as "Subwoofer Control". Also, each wire connects
separately to the radio amp.

I'm going to give up the idea of replacing the speakers with the Jensens and
look for exact replacements.

Thanks for the responses.

Well it's hard to tell what's going on in the pic. The brown/yellow wires
are the speaker wires from the radio. The capacitor on that side of the
speaker acts as a crossover to block the lower frequencies to the 6x9. It
looks like the green/blue and white wires may go off to another speaker (the
subwoofer)? I don't know enough about your car to say for sure. They may
even go to a seperate amplifer for the subwoofer.

Most aftermarket car audio speakers are 4 ohm. Delco always used speakers
that were 10 ohm, don't' ask me why. What that means to you is that there is
a small chance that running the Jensen 6x9 speakers with your factory radio
could damage teh amplifier, letting too much current flow.

So, if you were going to try to hook up your Jensens, for simplicity you
would just abandon the green/ blue wires on this side, and wire the speaker
to the brown/yellow. Unless you play your music at fairly high levels, you
probably won't hurt your radio.

Thanks for the advice. I think I'd better not experiment...wouldn't want to
have to replace that radio.

I can't figure out what terminology to use in looking for compatible
replacements.
