getmoney Posted June 28, 2007 Author Report Posted June 28, 2007 Do yall think this is a pretty good amp overall by these terms (power, efficency, and true rated power) (it has 3 30 amp fuses). Quote
getmoney Posted June 28, 2007 Author Report Posted June 28, 2007 I need to make a box i plan on using areoports but i dont kno how long or wide(3'' or 4'') they should be It will be tuned to 33hz. My max demeinsions are 48'' wide by 22 inches tall and 18 inches deep. Quote
sierra mist Posted June 28, 2007 Report Posted June 28, 2007 I have used the 4" aeroports and they worked great. Quote
sierra mist Posted June 28, 2007 Report Posted June 28, 2007 Did you get those 12's from Parts Express? I know they had a really good deal on those subs. Quote
getmoney Posted June 28, 2007 Author Report Posted June 28, 2007 (edited) I have used the 4" aeroports and they worked great. i got them from ebay, it was a damn good deal too. if i made a box with the sizes above(3rd post) how long would the areoports have to be for it to be tuned to 33hz?

Chris Posted June 28, 2007 Report Posted June 28, 2007 Do yall think this is a pretty good amp overall by these terms (power, efficency, and true rated power) (it has 3 30 amp fuses). Hate to break it to you, but with that kind of current draw, the amp would have to be 1ohm stable & EXTREMELY efficient to get you 1200 rms. Thats also if your voltage was at a steady 14volts + Quote 4 15" FI Q D2's in 12 cubes tuned to 32hz 1- T1000.1bd's 3 Maxx 29 deep cycles 4 runs of 1/0 gauge -Big 3 -Trunk sealed off from the cabin Custom 15.8 dual-volt switching MLA module All in a CAR.
sierra mist Posted June 28, 2007 Report Posted June 28, 2007 According to RF TEch, you have 9.1 ft^3 before displacements. With 8 cubes (after displacements I'm guessing), you would need (4) aeroport that are 12.62" long to have a tuning of 33hz. Quote
