Getting Perfect Sound in the Car | Crutchfield
Part 3 of our series: Jeff upgraded his speakers again ran higher-quality
wire and added a processor to sculpt the sound. He had to modify his door a
little to get the speakers to fit & mdash; but when you want the best
there's no need to let a little modification get in the way.

Back to Basics -- Car Audio 101
By Mike Stiers
So you've decided to upgrade your car stereo system? A great deal of
research and planning should go into this purchase since there is a lot to
consider. Do you desire a nice upgrade of your factory speakers, are you
looking for a Sound Quality overall of speakers, subwoofers and amplifiers,
or are you designing a vision-blurring SPL machine? It is important to make
a list of exactly what you are looking to replace or add to your audio
system so that you can prepare your electrical system for the investment to
Many people do not realize that their vehicles' factory electrical system
was not designed for aftermarket audio equipment. In fact, most factory
electrical systems can only handle an audio system of 600 to 1200 watts.
The lower end of the scale being the smaller vehicles and most foreign
rides, and the upper end being large trucks and sport utility vehicles. As
you increase demand, you need to look at upgrading your battery, alternator
and most importantly your "Big 3."
The battery provides reserve to the engine during starting, discharges
current to accessories, acts as a buffer between the alternator and all
accessories and after market audio equipment, as well as powers everything
active in your vehicle when the vehicle is off but in the Accessory (ACC)
position on the ignition. Your battery or batteries are extremely important
in determining what aftermarket audio equipment can be added and survive in
your application. As the demand becomes too great for the alternator and
the voltage begins to drop, the battery is relied on for its' reserve power
until the demand is reduced and the alternator can recover. This is why
batteries are commonly rated in several ways. The most common rating is Amp
Hour (AH) rating. This is a unit of measurement for battery capacity,
obtained by multiplying a current flow in amperes by the time in hours of
discharge. (Example: A battery which delivers 5 amperes for 20 hours
delivers 5 amperes times 20 hours, or 100 ampere-hours. So, this 100AH
battery can supply 5 amps per hour for 20 hours before dropping to
10.5volts. At 10.5volts, the battery is fully discharged.) Since
manufacturers use different discharge periods to establish their own AH
rating, Reserve Capacity is relied on heavily in the industry to
simplify battery selection. Reserve Capacity is the number of minutes a
battery can maintain a useful voltage under a 25 ampere discharge. The
higher the minute rating, the greater the battery's ability to run all of
your electronics for a longer period before recharging is necessary. Deep
Cycle batteries are different than starting batteries because they have
been specially designed for multiple complete discharges without losing
reserve capacity, but Cranking batteries will lose reserve capacity quickly
with repeated hard discharges. This is why Deep Cycle batteries are ideal
for the high demand of aftermarket car audio amplifiers. Once you have
determined the audio equipment you are interested in for your purchase, you
should contact a reputable battery manufacturer for their recommended
battery based on total wattage in the aftermarket audio system. This could
mean a simple replacement of your factory battery or adding additional
batteries depending on what you have planned for your amplifiers.

Extremely LOUD and CLEAN Car Audio - 4 18's 30,000 watts on ROCK - DOWN II
**Tremendous Bass 116**
I recently had a video go "viral" on the internet, and as usual, a lot of
people who didnt know what they were looking at, think that my system only
plays at full throttle and only rap music. Well i am here to tell you that
sometimes, i do actually turn the music down and listen at normal levels.
Its also well known, to those that know me, that i listen to rock, and a
few other types of music as well. My system has 30 speakers in it. 26 of
them are NOT subwoofers. I know it makes a lot of bass, but the mids and
highs EASILY keep up with the lows. The camera mic makes it sound like
everything is distorting but thats not the case in real life. Check out
this demonstration of something different then you are used to seeing from
me. The song is called "learn from this mistake" by one of my favorite

Grounds are good, remote turn on is good, power is good - something wrong
with the amplifier.
This video was taken while the car was off (around 12.0 to 12.2 volts)
however the exact same symptoms are occurring while driving (+14v).
The amplifier is NOT entering protect mode - the indicator light on the
front panel does NOT illuminate red (as it should in protect mode).
If you know the answer or can help me find it, please comment.
