02 Kicker L5 12" power handling

[KnOkIn It 420 10+ year member]

A friend of mine just bought 2 refurbed 02 kickers to replace his 2 fried 05 L5s. I know the sub are underrated like all L5s and I am gonna let him borrow my Orion 2500d (he actually had a FREE Boss "4000 watt rms amp") and wire it to 2 ohms...which is good for 1700 rms ,what should I set the gains to? They will be in 8 cubes tuned to 35 hz

ummm... honestly...

in 4 cubes a piece w/850 watts a piece, those L5s will either fry or smash their VCs to pieces in days... hours... maybe minutes...

Well yea kinda understood that,but I know the subs can take more power than they say (600w IIRC)...I am just tryin to get a idea of much more power handling there is

PM member "polecat". i believe he works for kicker and could help u out on that one.

Yea he does,but I havent seen him on the fourm.so idk if he changed his name or what

ok, i'll put it like this... my L7's are from '02, and i wouldn't feel comfortable giving them more than 750... maybe the coil could take it, but the suspension would let the sub bottom out with very much more power than that... ESPECIALLY in such a big box...

so i'm thinking an L5 wouldn't fare too well against ~900 watts in 4 cubes...

Okay let me break it down for u bro....I dont plan on...is this too fast for u....giving them 850/900 watts.I am aking if the handle ..lets say 700wrms each or maybe 638wrms...get it?

lol... lets go back over this...

A friend of mine just bought 2 refurbed 02 kickers to replace his 2 fried 05 L5s. I know the sub are underrated like all L5s and I am gonna let him borrow my Orion 2500d (he actually had a FREE Boss "4000 watt rms amp") and wire it to 2 ohms...which is good for 1700 rms ,what should I set the gains to?

you tell us what the amp is good for (1700 watts, which gives us the impression you want to use that much power) then ask what to set your gains to... but whatever...

we really can't answer that for you. use a DMM across the amp's terminals and use the voltage and impedance to determine how much power you're giving the subs... fiddle with the gains until the voltage matches whatever amount of power you want to give the subs...

that said... i don't know if the L5 can take 700 watts thermally, but mechanically they're fine, peaking at 10.2mm @ 49Hz, and rising rapidly below tuning (you exceed xmax around 30hz... i have no idea what xmech is, so my advice is take it easy). You'll need a subsonic filter with a steep slope, or maybe an active crossover...

but... proceed at your own risk...

if you use a DMM to set your gains, i'd use a 34hz tone (impedance will be around 5.14 ohms), so using sqrt(wattage * impedance) you'll want to see 55.5 volts across the amp's terminals... (assuming thats a mono amp... i think it is...). This could be a lil off tho... because i didn't take the time to do all the DVC stuff in BBP6, so i'd suggest measuring parallel impedance on your subs and punching that in when you do your calculations...

same question but with an '05 L5? Or is it basically the same sub?

if he runs that much power, just make a sealed enclosure.

ya, i had 04 model l5 12's, two of them, hooked up to a lanzar opti2000d in 2.5 each tuned @ 38hz, and they lasted ~5 minutes //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

f'in awesome, tho

i shoulda got the l7's, but i was poooooor
