Now, the biggest thing to remember is that for the most part, you aren't
going to overpower your speakers, most people underpower their preakers,
thus blowing them..
[]
I had the same thing explained to me. The less power you send to a
speaker, the less control that speaker has. Speaker cones like to move in
and out in a straight line. When too little power is put to speakers, the
cone starts "wobbling" and moving around instead of just in and out, thus
tearing the cone and damaging the speaker...

Subject: FTE Small - More troubles

OK I did some looking around on the firewall for some type of
resister/impedance module for the Blower fan motor control... Perhaps my
eyes are going bad, but I don't see anything but the plug that connects
to the motor itself, and another that plugs in closer to the heater core
area... The only "modules" I see are located on the fenderwall beside
the air filter. Exactly where is this item located again?? I have no
manuals for the truck yet.

The 2.9L still seems winpy to me even though the distributer has been
rebuilt, new cap/wires/plugs/filters and pickup coil. There are no
codes being thrown, however I feel this engine should be a bit more
peppy. Some of the power loss may be from the lack of downshifting
causing the engine to lug along in too high a gear, but from a standing
start the engine just isn't up stuff.

What, if any, modifications has anyone done to increase the performance
of the 2.9L ?? I found an RV Cam from Competitions Cams that claims to
boost Tq. and HP from 1500-5000rpm which sounds decent... I've also
found a "chip" listed for the B2 but its for a different year, so I am
wondering if anyone has triad any of this stuff?

I want to thank everyone who responded to my power and blower troubles,
unfortunately noone had a solution for my downshift trouble... Oh well I
guess I will ask Ken for some insight from the Drivetrain page.

SO after all this what did I find today in the driveway? A nice green
puddle under the fan/W.P. area... Guess I will have to brave these
bitter sub-zero temps and change the W.P. tomorrow.

A '91 eh? I think the best remedy for that would've been to drop the cash
on a BII a year earlier... But seriously, I've heard of engine ping being
a sign of worn rockers, which certainly could be the case in an 8 year old
truck.

I have a '91 Explorer that only pings in the morning, with the accelerator
all the way to the floor, and climbing a hill (or on a hot day in the
summer). I've replaced all the sensors myself because Ford gave this a
"clean bill of health". The advice I had on this site in the past was to
replace the EGR valve. The '91 doesn't have this. I also have a
"hypertech
chip" but have removed this with the same results. I use 91 Octane and if
use anything less, it really pings! But, the big question is...why does
this only occur in the morning or on a good hot day? I'm in Utah with an
altitude of 4500 ft. above sea level.
Any suggestions on this?

challenges or the somewhat (usually) decreased gas mileage and extra workout
washing & waxing outweighs the positives of full-size. Everything else
being equal, I think most people are much more happy with the bigger

Have to agree w/Keith, I really liked my 92 exploder, just wasn't big or
powerful enough. That's why I got a 98 Expedition. Similar in concept, just
BIGGER and STRONGER in every respect. 8 ADULT passengers, too. No regrets.

Subject: Re: FTE Small - Hey Ken, stereo list maybe

i think that one thing no one has mentioned yet is exactly how important it
is to make sure your speakers are not receiving signals they cannot handle.
if you send your 3/4" tweeters 60HZ tones meant for your subs, those
tweeters are not going to last, underpowered or overpowered. i personally
believe that it is just as important to cross all your speakers over at
proper points as it is to make sure they are not overpowered...
just a thought...

Subject: RE: FTE Small - Hey Ken, stereo list maybe

I've been doing audio engineering for about 10 years (professionally,
longer as a hobby) and that is the first time I have heard that. Given
what I understand of how speakers are made and assembled, I do not see how
speaker wobble is possible.

What destroys speakers from an under powered amp is clipping. When you
crank up your amp, and it has no more to give, it lops of the top and
bottom of the signal (clips the signal) and in doing so sends DC to the
speaker. It is the DC that burns out the voice coil. It does not make any
physical changes to the speaker, well unless you send it lots of DC...

You can run a speaker with a 1mV signal, so long as the amp does not start
clipping. In all my years I have never seen a speaker torn by clipping.
But I have seen many speaker voice coils damaged by clipping, including one
night that I blew out about nine drivers. I had help from the power
company though. They drop one of the phases to the club, the voice coils
were smoked before I knew what happened. Also why I won't touch QSC amps,
they have no under voltage protection... but that is another topic.

yes.... let's hear more. I am also in the market for a tonneau for my
'97. How water resistant is your La Bra? I live in Portland, OR & we
get some occasional rain.

where did you get yours? and how much? any drilling involved in the
installation? is it secure (meaning, can anyone steal it off the back
of my truck once installed?)

Look in the box that houses the blower, evaporator and heater core;
about halfway down you'll see a 4 connector plug and that's it. Remove
the connector and two screws hold the resistor block on. (A swivel may
be handy.)

First, let me say that I am in the process of trying to find a
fiberglass cover for my 91, so far all I have uncovered were 800 and 900
bucks, special order. (yes, that sucks)
Anyways, I currently have a soft vinyl cover and I would have to say
that a fiberglass is the way to go. Why?
1) no flapping around at speeds of 10+ mph
2) just plain looks better, IMO, blends in more w/ vehicle
3) One word: Secure. You cant really put anything valuable under a
softy. Of course, some fiberglass covers come w/ out locks...some...

Those are pretty much the reasons why I wanted a fiberglass. If you're
looking for which is cheaper, the vinyl cover, of course. But trying to
keep one clean in the dust storm that is Texas can be a challenge. Just
thought I'd toss in my 2 cents, for what its worth...

Well, let's see. For DC or a square wave, that's true. The "Crap" comes
out
pretty much the same. But, most of our music is comprised of sine waves,
and
the crap becomes pretty different. In fact, for a nice perfect sine,
peak
is 1.414 times the rms power, which is not the same. For any other
waveform,
you need to go through the math, or get a peak/rms power meter. Oh yeah,
peak
power has an electrical name also. It's called "Peak Power".

Yup. Good advice. Just remember that power ratings on amplifiers are
pretty questionable. Kind of like horsepower ratings on compressors
down at sears, for a while power ratings are measured at the absolute
peak output just before the whole thing melts down. At a computer show
the other day, I saw a pair of speakers advertised at 480 watts, over....
