hey everyone. just got back from my seasonal job. got about 2gs canadian to spend on some upgrades. anyways im lookin for a 60/40 spl/sq sub. a couple guys here told me to get the fi bl. i got a rockford T2000bd. i was lookin on the fi site but cant decide if i should get the bl or btl. the bit of noobness in me tells me to get the btl and run my amp at 1 ohm. yes i got the big 3 and 1/0 wire, all that good stuff. plannin on gettin 2 kinetik batts as well. anyways should i get the bl and run it at 2 ohms or the btl and at 1 ohm? also what do all the options mean on the sub? i know i want the dialy and just a plain dustcap. whats all the others mean and should i get them on either sub i choose to buy? i wanna buy really soon just waitin on u guys good opinions. thanks in advance
ahhh ok. think the bl is gonna be louder then a re audio mx? i got an optimal box for the mx as well. also can it handle 1500wrms dialy? what options should i add?
If you got a loaded BL you'd be fine, but since many RF 2ks are rated to put out between 2500-3000 I would go with the BTL. You will have similar output and not much noticable difference in SQ imo. Your call, it may not be worth the money for similar results.
yeah got the ho alt. 200 amp. i already got a mx. im thinkin about gettin the xxx or the btl. i can biuld enclosures and tune boxes as well so theres no problems there. gonna be gettin 2 kinetik batts as well, one for the front and the rear. i just want something thats gonna be louder then my current mx setup. 2.1cf3 tuned at 33hz, but still retain some sq. im not stuck on fi or re though if someone thinks that theres a better sub for my needs then please let me know
Well thats a wrong point.. you still need the alternator if you plan to draw a large amount of current for any extended length of time. Batteries will only help for short bursts.

Is all you do is spit out stuff that has been told to you?
My point is extremely correct. I know from this thing called EXPERIENCE. Not from what someone that "knew what they were talking about" told me. I've built systems from 2k-4k with a stock alt. Voltage stays at 13.7-14 even at idle on several steady bass songs. Battery power is pretty important. It can take the big amp draw while your stock alt recharges it.
Please, if you have any other "parrot" comments, keep them to yourself to me.
I don't like to brag but I've got more knowledge of electrical devices than most people on this forum with a few certain exceptions.
So no what I say does not come from anyone else.
The laws of electricity are really not that hard to understand and I don't know why some people have such a problem with it. Lets say you have a constant average draw of 150 amps, and a supply of 90 amps from the alternator, with a battery (how big is irrelevant) in the circuit. Simple math tells you you're drawing more than you're supplying. Additional current to make up the difference is drawn from the battery and voltage drops as that happens.
Now where the size of the battery comes in. If you have a bank of five 2000 amp batteries, you can draw a lot more current before voltage drops to a critical level than if you had one 750 amp stock battery. But in either case you will eventually run out of reserve in the batteries, and if the alternator can't supply enough current you're SOL.
It is not a matter of if but when. Adding battery power delays the symptoms but doesn't solve the problem.
so i could theoretically run 2krms on my stock 90amp alt if i had a good battery bank??? but wont that cost more than just gettin a ho alt?
im not tryin to instigate anything, its just a real question that i have. I want to run ~1500 rms to subs and 4-500 rms on my front stage but a lil weary about adding a HO alt.
Some people do just that, spend more on batteries than a HO alt would have cost to do it right. Which I do not understand. Not only is the problem not really fixed but you have all that extra weight too.
so if im playing my system with 2krms on a stock alt and maybe 2 big batts when will the alt have enough time to recharge the batts? or will i have to turn down my music for a while so that they can get the voltage up?
are these questions legit or am i just not understanding...
To you and many others I really don't care what I have proved
And I certainly did account for the fact that the current draw is not constant. Say you've got a big amplifier that can draw 300 amps. Playing music a reasonable assumption is you could be drawing 150 amps average.
so anyways...what do u guys think about the xxx? gonna be much of an inprovement from my mx? right now im running my mx at 2 ohms as well and would be run the xxx at 1 of coarse
M.S. is just a silly scrub. Also, like mentioned music is not a constant and who says you have to play full blast all day long? You can turn the s hit down for an hour or so and let your alternator recharge your batteries. You don't have to drive around town all day long playing your music as loud as possible.
so how big of a battery would i need to run 2krms total? would replacing just the stock battery be good enough or how about just gettin another battery for the back?
sorry to thread jack you wayne felix but i think some of my questions could help the both of us.
A kinetik 2000 or so would work perfect. I would just put it in parallel with your front battery.
I used to run 2k @ .35 ohms daily with no voltage problems at all with a kinetic 2400. I'm about to put 2k @ .5 ohms in a truck, and his extra battery is going to be a kinetik 1800.
no prob abarca, i wondering the same thing. does it matter if ur battery in the front is the same or wha? i thought having 2 different batteries does something. like they drain off each other or something? also i think im gonna go with the xxx unless someone has something to say about it
Most people don't disconnect power to the electrical system when doing something as simple as connecting RCAs. I don't even.
It seems as if you don't.
I believe you can run 2k on a stock alt with a good extra battery from experience.
You believe you have to have a HO alt when running 2k because someone told you that.
That is pretty much the argument. I see that it is going nowhere with you, and I understand that some people can't comprehend some things, but it'll be alright
Its a moot argument because simple facts about electrical systems have already indicated you are wrong. When the car is running the source of current draw is the alternator which is supplying power to all the electronics and recharging the battery. You can't throw batteries at a problem related to current demand and hope its not hurting your car charging system.
" You believe you have to have a HO alt when running 2k because someone told you that. "
You really can't get anything right at all. I know what I have learned about electronics. As far as it relates to car audio I have proven it to myself by experimenting. I seem to remember a canaan post in another thread about how your system works b/c you don't play it full tilt... now that would certainly explain some things. I would want an electrical system to handle anything, any music, any volume, for any time. And I recommend to people the equipment they need to do just that.
What I really wish is I could play with some of these systems. If they have stock alts like you say, with the right CD I am certain I could make the alternator or amplifier fail under stress.

i read on here i think that fi was a bad build quality. (tensil slap) i have been looking at the mx by RE audio and would go with that over an fi sub. just my opinion and what i would do if i were you after reading these forums
oh ok... yea i heard good things about fi. a lot of my friends talk about fi and my onw friend has a pair of ssd's and they get really loud. thanks for clearing that up for me and the OP m.s.
