IH8PunkRok Posted November 15, 2013 Report Share Posted November 15, 2013 Indeed you will be in mod. I assume those LP amps are a/b? This may hurt you on fusing but you can probably still get into mod1 of you can hold a fuse -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...

I may run a single Linear Power LP2400 if it is avaliable be then ... 8 ohms mono. So can you guys sort of explain this fusing thing to me ... I know each amplifier has internal fusing (three 20 amp fuses) ... (not sure about the new LP2400) ...

IH8PunkRok Posted November 15, 2013 Report Share Posted November 15, 2013 each class has a number associated with it. for this example I will use Street 1 as it is the one I am most familiar with the number is 550 this is the maximum cone area + 10xfuse so say you have 1 12" sub this is about 113 sq inches of cone so 550 - 113 = 437 437/10 = 43.7 43.7 is your maximum fuse rating but since you are allowed only one fuse in street 1 you have to run a 40 amp fuse or less external fuses are mandatory don't worry about on board fusing one thing you really need to check on is the iso mounting of your subs. they may count as 4 drivers instead of two either way worst case scenario Mod1 = 1000 10" subs = 78.5 78.5 x 4 =314 1000 - 314 = 686 so 68.6 amps of fusing I am not sure but I think mod1 can run two fuses (check the rules on that) in which case you can run 2 30s or do like the pros do a 60 amp and a 5 amp -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...

My Iso-Kits will be used elsewhere ... If I can get my hands on the enclosure I'm looking at ...

ALPINE408 Posted November 15, 2013 Report Share Posted November 15, 2013 Your best bet with 15s is mod3 top scores are around 153 to 154 if you could drop fuses to mod2 and still do a 150 you will be very competive in spl to but if you are looking for bobos mod3 you need to do park and pound for bobos as well tho and that's 30 seconds ave on music full tilt meter 6 feet from the car Have you ever had your woofers blown?

skittlesRgood Posted November 15, 2013 Report Share Posted November 15, 2013 the mic sits on the seat, elevated on a stand, a few feet from the windshield. you usually want to hold a tone for about 4 seconds just because the score could go up a tenth or two. maybe that's not a concern for you. Ok ... Makes sence. I'm going to assume that the mic takes the place of the driver's head (ears) ... ... and what do you mean when you say this ??? the mic placement likes lower frequencies. If I can get the enclosure that I have in mind (already built in another truck) ... I think it is tuned aroung 40 htz (I really need to verify this ASAP) I will be able to give more details on this (and the drivers) if I can get my hands on this enclosure to put in my truck ... Not sure at this time if it is even possible to get this ... But would be nice, It is a well built enclosure !!! But it's things like this I need to know if I need to actually build an enclosure because I kind of want the highest frequiency possible cause lower frequiencies tend to "destroy" interiors ... Trust me, I know from personal experience ... Now I can say this about the Blow Through setup ... I will be fixed below the windowline to where I can completly cap it off for Sound Quality competition ... Don't want the SPL drivers making any unwanted frequiencies during testing / judging ... 1000w at 35hz isn't going to destroy anything man. trust me, i know from experience lol. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

This sound about like my game plan Yea, low 150s is all I'm looking for, just want to stay in a low enough class so I won't get ma but kicked by a raw SPL vehicle and my does Sound Quality also ... but if you are looking for bobos mod3 you need to do park and pound for bobos as well tho and that's 30 seconds ave on music full tilt meter 6 feet from the carI do not have or will have enough battery power for this ... nor do I want to put my truck through that kind of punishment ...
