(Since we are dealing with maximums, not to mention differing tastes in music and listening
volume, there is a healthy “fudge factor” built in here.)
BUT, if you want two 300xs’ pounding away at 4 ohms bridged,
that’s 1800 possible watts, or 18 X 7.5 amps, for 135 amps. You only have 40 to spare. High-
performance listening requires the right equipment. Either you invest in a more powerful
alternator to make up the extra current, or
is going to have to come up with the
additional 95 amps.
This is not a good situation. Most batteries are of marginal construction and made of recycled
materials. Hence, they perform poorly, and break down quickly when used outside their intended
roll of starting the engine. The longer a battery is discharged, the longer it takes to recharge. Most
batteries take a lot longer than you think. Every time a common lead-acid automotive battery is
deeply discharged, it is damaged. The longer it is left discharged, the greater the damage is.
600 watts at 7.5 amps per every 100 is
43 amps. You are home free.

U.S. AMPS SPL SERIES BATTERIES:
By default, we have become battery experts, so
much so that we have our own brand, aptly named
the U.S. Amps SPL Series, sold through our
Motorsports and Consumer Electronics divisions.
The SPL Series consists of two 12 volt models, the SPL-
1000 and SPL-2000. They are the finest lead-acid
batteries available. SPL Series batteries are made of
99.97% virgin lead. They are 30% smaller and
lighter than conventional batteries, and will cycle up
to 10 times more often without losing their
specifications. The pure-lead construction allows for
more powerful discharge, faster recharge, and in
most cases, installation without a battery isolator
when used in parallel with the factory vehicle
battery.
