isn't the mayhem rated at 2500rms?

isn't the knob a remote gain knob?

dammit i thought some of them were 1 ohm amps (1 channel too)

wana post up the power ratings of this? sorry, i got confused about these amps with them being rated at 2 ohms bridged or not...

i dont get it, thats an spl vehicle? You only got 140 with a few mts and 16v setup?

I tried to put it at about 20hz. I couldnt tell when i played a 20 hz the effect it was having. I can still play 10hz and 15hz so it really doesn't make sense. Same goes for my LPF I tried setting aroudn 80hz. Okay so your saying it shouldn't have made much of a difference and should still be about 33hz?

oh lol good stuff. wow your really helpful. Thanks a lot. I'm going to start figuring out how to calculate this stuff by myself, I can figure out the cubic feet but thats bout it That didn't turn out bad at all nevermind nvm as in thats wrong ? I'll take a look at that and start testing. 18" only one of them

I got my two for free, I've seen people use them and work pretty fine.

oh lol good stuff. wow your really helpful. Thanks a lot. I'm going to start figuring out how to calculate this stuff by myself, I can figure out the cubic feet but thats bout it That didn't turn out bad at all

Did i forget to mention the top is double baffle with flushmount, so 1.5" of mdf? IDK if you got that, but im fine with 7.57ft^3 at 31 hz I really hope your right cuz I have absolutley no problem with 31 hz

I don't think it is an L turn, is it? did you do it as internal dimensions or external?

It really doesn't, it might not be exactly 21" but I figured I cut an inch off. I can go cut .5" off soon. i guess try it at 20.5 or 21", either way works

thanks bigjon BUMPs!

Alright. Vids of it will come sunday sometime, I'm going to washington tommarow for my uncles promotion or something. btw the hairtrick wasn't anything special window was rolled up a good amount of the way, but i liked it lol. One 18" Btl 7 cubic ft box Port dimensions are weird, i'll link you to another post that i made about it. http://www.soundsolutionsaudio.com/forum/i...showtopic=26394

chit yeah thats true.... Wanna point me in the directin to calculate port tuning? No one is helpin me out/can't help me out, so I wanna find it wihtout rebuilding hte box. I can live with 35hz but if too much higher then its rebuild.

hahah yeah, screw it, it sounds good. I will try out a side port or just another slot port next time, but I'm going to finish the system before any rebuilding.

I think its .5" longer, but also a little bit skinnier by like 1.5". IDK... If i were to fix it, it would mess up the entire box... the two tops are on, the flushmount is glued on to the baffle below, and then theres screws and I jsut think that it would basically be junking hte box....

I need to find out my tuning because it doesnt seem near as loud. I played 30 and 35 hz, those seemed decently loud but more of destroying the car than bass. I wil try it soon

Alright so I have my BTL in my ported box (tuning is messed up I have to redo it I think) and I am powering it with a 1200 watt hifonics with chit 4 guage. Waiting on installing my batts, big 3, and 2 ought. I was playing hz tests and I was like fudge it its moving some air, lets see if i can do a hair trick. So I had this girl put her hair in my window and I rolled it up a till there was about 3 inches left. I played a 40hz tone, I STILL dont know what my tuning is but this gets pretty loud, and it was moving her hair! Not all of it but it was making it flap in the window between the outside and inside of the car. What do you guys consider a hairtrick? Ive seen them with windows up and down, IDK, I know its not amazing, but still pretty impressive in my view. Gets loud.

Wheres the rest of the instal? I looked and couldn't find any pics of ur wiring, amps or batts! BTW, I have very similar batteries to u. I have the UPS 12-310FR. Two of them where did you get them?

thanks for posting! so if I took 2 dual 4 ohm subs, 2 wires coming out of the box for each sub, going into all the + and - ports for the wires, the amp would read it at 1 ohm as long as it was parallel

lol i take it you dont like the amp/ its chit?

how about that sub in the background? what is that? anyways, sick box, looks cool

oh crap, sorry. 44" width, 17" height, 27" depth. 7cb ft internally. Built with 3/4" MDF wood.

Alright, I can get this amp for 350$ maybe a little cheaper. Would this be good for an 18" btl? I don't want to push 4400 rms, becuase my box is 7cb ft, so I figure I could just put the gain down a great amount. I know these are power hungry, but aren't tehy like 450 amp draw? I would have 2 C&D tech batteries (88 amp/hr with a rating of 340 watts/cell), 2 ought wiring, 200 amp alt, and soon down the line upgraded under the hood batt. Would that be sufficient? Would these be a good match if I set the gain according to like 2500 watts?
