[QUOTE="SoundsUnlimited, post: 200682, member: 546257"] Mainly it is different classifications of how many woofers you have, the size of the woofers, the amount of amps power and such, then what kind of modifications you have done to your car..such as a WALL..etc These rules are for DB DRAG: Street A – A maximum of 2 subwoofer amplifiers may be used. Total subwoofer amplification is limited to a maximum of 4 “non-bridged” output channels or 2 “bridged” output channels. (Please see the definitions section for more detail regarding bridging.) o 1 to 2 woofers 12-inches in diameter or smaller o OR a single woofer that is larger than 12 inches in diameter but no larger than 15-inches in diameter · Street B – A maximum of 4 subwoofer amplifiers may be used. Total subwoofer amplification is limited to a maximum of 8 “non-bridged” output channels or 4 “bridged” output channels. o 3 to 4 woofers 12-inches in diameter or smaller o OR a pair of woofers that are larger than 12 inches in diameter but no larger than 15-inches in diameter o OR a single woofer that is larger than 15-inches in diameter but no larger than 18-inches in diameter Street Division: · Amplifiers used for non-subwoofer applications will not be counted. · Subwoofers may not contain more than 2 discrete voice coils per sub. · Cargo vans and commercial vehicles are prohibited from competing in the Street Division. · Sponsored vehicles are not permitted in the Street Division. Super Street Division · 1-2 Woofers – No Walls · 1-2 Woofers · 3-4 Woofers · 5-8 Woofers · 9+ Woofers Extreme Division · 1 Woofer · 2 Woofers · 3-4 Woofers · 5-8 Woofers · 9+ Woofers The classes listed above are the recommended standard classes for dB Drag Racing.
