Good point, Shaun. I've never had to resort to chokes, but I had heard they
work when all else seems to fail. A good clean ground is, in my experience,
the most important element.
Of course I've never gone for the truly "earth-shattering" sound systems in
my own vehicles-- My Dak is 35Wx4 into the fronts and rears (supplied by the
head unit) and 150Wx1 into a Kicker Solobaric. Clean sound, no distortion,
tight bass without being boomy. I'd have put a smaller amp on the sub(75 or
100 max), but the 150 watter was what I already had left over. Keeping it
simple turned this into one of my best sounding vehicles. Capable of loud
volumes, but rarely do I push it past the level where normal human
conversation is possible. On long solo trips, I crank her up a bit, but I do
like to hear my engine rumbling along as well. I've got nothing against
those that like the loud booms (well, at 3:00 AM as they drive through my
parking lot I do!) I just happen to like to hear all frequencies in my
music. ;)
As always, YMMV...

Subject: DML: Induction Noise (Amps/Speakers)
I've been browsing some of the solutions to the engine noise problem and
I've tried all those before with limited success. The only real solution I
found (when I was into mind numbing, ear-splitting acoustics) was a two
pronged approach. First off, run a "ground loop" isolator between your
stereo
head and your amp(s). This will eliminate the multiple grounding point
problem. Next, while you are at your local electronics store getting the
ground loop isolator, buy a few clamp on ferrite chokes. Wrap each wire
leading to a speaker (as close to the speaker as you can get it) through the
choke several times (same number each speaker: don't use more wraps on one
than another) and this will kill any low level inducted sources (engine
noise)
and drop a small amount off of the main source. Since you guys are talking
*way* over a few watts here, I doubt you will notice any real power or
signal
loss. You should then be able to deafen yourselves and your neighbors quite
handilly without any engine noise for those outside your truck to be
bothered
by: well, beyond the natural engine noise (if they can hear it over the
sound
system).
