ohhh i see well then idk

i know mine isnt bottoming out because if it was both would more than likely

how much airspace is yours built for

also wat electrical do you have for that sundown at .5,i was gonna run that but wanst sure how much electrical i was gonna need

i have 1/0 wire for my big 3 and from front to back and i have a red top in the back that is 1000 cca and up front. the box i have now is about 2.5 to 3

have u metered it yet

 

[pimpinmex803 10+ year member]

my tl score with a zx1500 was 142.3 but im going to meter it this week some time i know its going to be much higher

 

[king ranch 5,000+ posts]

well then i should be in the 145 range i am figuring since its ported in a box around 5.2net

but idk how that would go so well since its tuned to 33-34hz

wat do you think i would be around

also how much are you giving them with that sundown at .5ohms (how much does it put out at that ohms) and whats your voltage drop

 

[pimpinmex803 10+ year member]

what car are you useing. its alot harder to get a trunk louder then a suv. i know that im giving thim over 2000 just never tested them out as for the voltage drop have no clue im going to find all that out this week.

i have the setup in a truck 2001 f150 king ranch with the bucket seats in the back with the rear console i took the rear console out and got a bo to fit back there subs up port back

if you know wat kind of truck i am talking bout then u see wat i mean if not then idk if you ever seen a harley davidson f150 its the same design just different interior

 

[pimpinmex803 10+ year member]

yeah i know what you are talking about

 

[king ranch 5,000+ posts]

so wat do you think i would hit possibly

i am giving them around 1600rms

 

[pimpinmex803 10+ year member]

if i had to guess i would say around 143-145

 

[king ranch 5,000+ posts]

yea i was hoping to be around the mid 40's so if i hit 145 i would be extremely happy

once i get my electrical up a lil better i am gonna get it metered right now i am getting drops to 13 so i want that to get up and then i will test

and if you are hitting 142 sealed in a small box i am ported i am sure i can gain at least 2-3db's

im going to build a new box soon with aero ports around 4 cu ft my trunk is very small. one of my friends has a altima with two 15 ported at 6 cuft with 4 4" areo ports hitting around 146.9 with one sundown 1500

Dropping to 13 volts isn't bad..

wtf are you talking about

 

[king ranch 5,000+ posts]

well its around 12.7 with lights on at night at idle on full tilt on the song put on dropping to 12.5-12.7 and thats with no big 3 that should give me right at 13 volts and i plan to get a hc1400 or something bigger upfront

only got a lil gold duralast upfront i mean its rated at 750cca and 1000amps so its not that bad
