12. SB5 is the only class open to any vehicles that use a system voltage higher than 14.7 volts

or that uses multiple alternators.

just run the 200 amp alt if you can, that will be enough with all the battery reserve you have.

Yeah, I will just pull the 2nd alt when I compete in july. Didn't see that rule before..... I lost a comp once due in part to the winner using a sine sweep in sb3. The guy "couldn't find" the disc he had used when asked about it. So yeah cheating is not cool although I believe it happens quite often.

I guess the "oldschoolboomer" comes from a neighbor nick-naming me "the boomer" back in San Jose the eighties. I change equipment (far too) regularly so I don't have anything too old anymore. I guess I could change my name to just "oldboomer", but it doesn't have that special something my current name has.

new subs and box for the heck of it. Will be doing sb3 at the heatwave.

 

[oldschoolboomer 10+ year member]

missing one sub

that says 389.7Ohms!! GLN305 is hooking me up with another one though. great guy to deal with!

hooked it up to a crossfire cfa202 at 1 ohm stereo and even with one sub just floppin' and a total rated power of 200 watts to all 7, it sounds like it will be loud. The specs on the box are 8.7 net tuned to 35Hz with 127 inches of port. port fires up and will be drivers side. Box is designed to fit right on the back seat though it may end up on the floor if it meters higher that way.

I never understood the multiple alt rules. As long as its no above 14.8 you should be fine.
