Silver Member Username: Sx3Rockford, Illinois USA Post Number: 344 Registered: Mar-05 | Right now I have 1 15" DD 9515 (dual 1.5ohm) in a 3.5ft^3 box tuned to 40hz. Im powering it with a Directed 2400D. I have it wired at 3ohms. If I would want to compete what would be the best thing to do in order to get more out of the system? I have a regular battery (750CCA) and a 105 amp alternator. |

Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3580 Registered: Oct-05 | put it in a bigger box... and give it more power, i think that directed does 1200 @ 1, and 2400 max.. bigger alternator, at least 225a and yes, 1/0 awg wiring |

Silver Member Username: BernymacRialto, CA United States Post Number: 299 Registered: Sep-04 | also add a extra battery in the trunk. I would either go with two yellow tops or one odyssey 1700MJT or the 2150S. |
Gold Member Username: TheelfkeeperStockbridge, GA USA Post Number: 3043 Registered: Feb-05 | well, to compete, in SPL i assume, an alternator wouldn't be needed but would be nice for the daily driving. you need to figure out what form and class you will want to compete in first and read the rules. DB drag, MECA, ISACA...the number of woofers, power, batteries...ect...all affect what class you fall into and what you will be competing against. i'd figure that out first, then look into what upgraded you can do. |

Silver Member Username: Sx3Rockford, Illinois USA Post Number: 352 Registered: Mar-05 | Aright I have actually wired it at .75ohms before and it played fine until it blew my 80 amp in-line fuse. I just wanted some oppinions beacasue I obviously dont want to fry my amp. Any suggestions for an in-line fuse for the amp if I were to get 0awg wire and possibly plan on burping it at .75ohms? |
Gold Member Username: Dustin3Tigard, OR U.S. Post Number: 3632 Registered: Oct-05 | you will stil want an alternator even when competing because im assuming you want the most out of ur amp, which most amp are rated @ 14.4v, so if you wanted the full power and wanted ur car to run well you will need a new alternator. every little bit of power is great, and getting a big alt, + some batts will help you get the most |
Silver Member Username: Sx3Rockford, Illinois USA Post Number: 353 Registered: Mar-05 | I've always heard that if you just add another battery its not good for the alternator. Is that true? Why is that, and would it be a good idea at all to just add another battery and then later get a new alternator? |
