are you allowed strapped amps?
I'll assume you mean 2 channels out... because you could take a 4 channel amp and bridge the outputs...
btw... first mistake was letting Yuli write it [img]tongue.gif[/img]

Rookie 1
Maximum total inline fuse rating of 80 amps is allowed between the battery and the amplifier(s)
Primary fuse(s) must be located under the hood and be easily accessible and visible
Maximum of one battery can be used
No more than 2 Farads of capacitance can be used
Amplification will be limited to a maximum of two channels per loudspeaker. A limit on amplifier quantity is not enforced therefore either a single 2 channel amp or 2 monoblock amps may be used.
*Note* It will be at the discretion of the judging staff as to whether an
amp is a true monoblock or an internally bridged two channel
amplifier.
Competitors will be further divided based on the cone area of all woofers in their system with a diameter of 8" or larger. The three divisions are as follows:
0-144 sq" (1 12, 1 10, 1-2 8s)
144-300 sq" (1 18, 1 15, 2 12s, 2-3 10s, 3-4 8's)
301+ sq"
*Note* woofer diameters are manufacturers listed size not the actual external diameter of
the loudspeaker

Q and A
Q: How can I tell if my amplifier is a true monoblock or an internally bridged two channel amplifier?
A: The best way to tell if an amplifier is a true monoblock is to consult the owners manual. A true monoblock amplifier can be strapped with another identical amplifier to double its output. If the manual mentions a procedure to connect two of your amplifiers together in order to double the power output then it is considered a true monoblock amplifier.
