@ak : after the discussion seems kenwood is turning out to be the best option.so think would go with that(keepin in mind any future upgrades as well). |

@b&t : definately got your piont sir,what do you say about getting a kenwood KAC-9103D (1800watt mono) and pairing it with a Ground zero Radioactive GZRW 30SPL or keeping the same amp and getting 2 jbl gt5-12/2 pioneer DVC307 D4 would be a better option(in terms of best output amongst these 2).also if you could let me know the price for Ground zero Radioactive GZRW 30SPL. |

HAT'S off you as well GUNNU PHAAJI. rather i am so overwhelmed by the tremendous support from all the TBHPIAn's, at least in todays materialistic time no one has time to help each other,here we have a whole community trying to help each other from every part of the country(some fellas from abroad as well). Thanks to you all for this.... |

i agree that they would go lower. however i'm not sure about the loudness and more cone area bit. 22/7 x 8" x 4 = 100.57 of cone area. 22/7 x 12" x 2 = 75.43 of cone area. guru toh aap ho sir... lemme know if i am right or wrong!! |

B&T, you are right. 2 x 12" indeed have more cone area than 4 x 8". 22/7 x 6 x 6 x 2 = 226 sq inch 22/7 x 4 x 4 x 4 = 201 sq inch |

Arrey bhai ..The only advantage is that the 8" drivers are likely to be much faster due to lower cone mass |

..but the 12" need to move less (linear distance) to produce the same SPL... to cust a long story short there are no absolutes. it depneds on the install, cabin, design of sub and box (if one is using a box) etc.. |

Originally Posted by navin well actually they have about the same cone area. 8" is about 220cm2 and 12" about 440 cm2 but in general the 12" would have more Xmax and lower Fs. more Xmax means volumme of air displaced will be more and lower fs means it can be tuned to go lower. |

for that matter, you can even have 2 x 18"... and nothing would beat that, say if i had to choose from options fitting in the tray, three 8 inchers would fit, two 10 inchers would fit and only one 12 incher would fit... then i'd go for three 8 inchers for SPL. coming to think of it, i would like to know how does a sub work in a enclosed boot... like how much difference does it make with a sub being installed in the tray vs a sub in the boot?? |

..this is not the case practically and actual cone area is a conical area which increases for cones with deeper profiles. So there! Over to Navin! |

Navin-ji, you answered from the mounting (IB/box) p-o-v. Perhaps @montyguru is asking about the end effect inside the cabin? IB directly firing into cabin versus sealed box kept inside the boot firing into boot and sound coming through rear seats? Not limited to primary characteristics related to mounting arrangement. |
