CONNECTING YOUR SUBWOOFER TO YOUR AMPLIFIER
The GT5-12 subwoofer has a single

a. The total system impedance of voice coils (or woofers) in series can be calculated using the formula:
Impedance = w1 + w2 + w3 ...
b. The total system impedance of woofers in parallel can be calculated using the formula:

consider the following rules:
1.Do not mix different subwoofers or enclosure types in the same system. Subwoofers being used in the same enclosure or powered by the same amplifier should
be identical models. Mismatched woofers and enclosures can result in poor system performance.
connect two identical woofers in |
series and then connect that pair |
to another woofer in parallel. If |
your system will include an odd |
number of woofers, be sure to |
connect all the woofers in either |
series or parallel according to |
the rules that follow, in order to |
maximize the power available |
from your amplifier: |
w11 + w12 + w13 ...
where w is the nominal impedance of the woofer.
The diagrams at right show series and parallel speaker connections.
