Single 8.5" port, but you need huge power to make everything move, which you have covered.

 

i would argue otherwise tho, you see how much port there is in dave's car, way more area than a single 8.5 inch, actually even more than single 10 inch. and it worked way better than a single 8.5 inch.

it all depends.

 

reason i asked the black festiva i built reacted better to one big port that 2 not so big lol and as for needing big power to make it work i think daves got that covered lol

 

Anyone can build a box and throw tonnes of power but Team TFONE/CTSOUNDZ are basing our builds on box efficiency. Better to have an efficient box then dump the power. As you guys can see, last Sunday in kingston in qualifying the car did a 157.0 in qualifying with more to spare. Then, the car still did 155.0 with one amp and one sub on two batts during elimination. The week before in Hamilton the car did a 156.7 with one amp and two batts. BOX EFFICIENCY is the key fellas.

 

did u loose an amp dj ?

It also took some decibels with it as well.
