I'm looking for a amp to push my 2 SPL W12s there rms is 2400wx2@ 1ohm. the only thing i can find is a audiobahn amp is it worth 360$??
If nebody knows of other amps that can do this drop a link here.

damnit, I had a whole response typed up and then it didn't post and I lost it....in summary, those subs can't handle anywhere remotely close to 2200rms, don't dare go more than 1000rms each or there's an extremely good chance you'll melt down both of them. Also, those subs are dual 1ohm, which means a 2ch 1ohm stereo stable amp won't work, you'll need a 1ohm stable mono amp.

Something like a hifonics brutus 1800d would work, but be vary careful with the gains, who knows when those things will go up in smoke. And in the future, be very wary of any sub that claims a power handling greater than 6-700rms and is less than $200, and be even more wary if the only "specs" that the manufacturer lists are retarded cosmetic shit instead of the T/S parameters.

They had a lifetime warrenty on them pretty sure. So if i smoke them get a new set. thinking bout getting rid of them for some mtx punch.

that warranty doesn't include abuse, and overpowering is abuse

why is that?

each sub has 2 1ohm coils, which means each sub can be wired to .5ohm or 2ohm. Then you can take the two subs, and wire them together into a SINGLE 1ohm load or 4ohm load (depending on how you wired it). If each sub was say 1000rms, in order to power them properly you would need an amp that did 1000x2 @ .5ohm or 2ohm, or an amp that did 2000x1 @ 1ohm or 4ohm.

I know its been awhile since i ever made a reply to this but been kinda busy. I wired them like the mnual side one side get the straight postive the other gets the stright negtive the criss cross. So what amp would i need? Or u think i should just try to sell them and go with somthing else? I know i want 2 12s that will thump the shit out of the maro.

you can wire each sub in series to bring up the ohms to 2ohms, then wire the two subs together in parrallel to bring the two subs back down to 1ohm. if all you are planning to do is run those two subs i would get a mono punch amp from rockford fosgate they are iohm stable, and that will be more than enough. you never want to run your subs so high when down to 1ohm, you can burn out your voice coil in a snap!!!!

oh and another thing read the specs on that audiobahn amp carefully they tend to overate the power rating to fool people that don't know any better

it wouldn't burn out any faster than at say 4ohm if it was the same power

Dreamspawn

So i need a 1ohm mono amp. Kk let the search begin.

schemo
01-10-2005, 01:24 PM
any amp working at 1ohm is working for times as harder than it would be at 4ohms. touch an amp working at 1000watts compared to an amp at 4ohms pushing the same power. which one feels hotter? 1ohm draws and comsumes alot more power than 4ohms.

and more power always equals to more heat and distortion (at higher levels).

all that would be needed is one low wave hard wave and you can easily burn out a voice coil, like you said speakers in your previous post the subs are warrantied, but not against abusive actions.

just my input from experience, by all means i am no engineer.

p.s. dont listen to a newb that questions/argues with sr20

bumpinstang77
01-10-2005, 02:40 PM
Schemo your wrong. 1 ohm stable amps are usually class D which mean they have a different way of making the power and a lot of class d's running at 1 ohm are working under less stress then a class a/b amp bridged at 4 ohms. And class D amps usually run very cool at 1 ohm most class a/b amps running at minimum impedance get VERY hot. Blowing your speakers has nothing to do with what impedance theyre running at. 1000 watts at 4 ohms and 1000 watts at 1 ohm is the same thing. So go esearch before you post and give the wrong info to people.

just my input from experience, by all means i am no engineer.

yes an amp that is running at 1ohm is working 4 times as hard as when it's running at 4ohm, but a 1ohm stable amp running at 1ohm is working just as hard as a 4ohm stable amp (such as a bridged 2ch) running at 4ohm. In either case you're running the amp at its minimum impedance, and assuming similar design and build quality, you can expect the same amount of distortion and reliability from either. And as bumpin pointed out, due to the lower efficiency of the class ab 2ch (assuming it is a class ab and the 1ohm amp is a class d, which is normally the case), it will actually run hotter and suck more power from the electrical system than the 1ohm amp.

As for the subs, speakers can only blow 2 ways, thermally and mechanically, both of which are directly related to the current running through the coil. More current means more motor force which means the cone moves farther, and more current means more heat buildup in the coil. You have to treat the 2 coils independently, since they are in fact, independent coils doing their own thing. If you have a dual 2ohm sub wired in series to 4ohm that's receiving 1000 watts, you will have 15.8 amps (P=I^2*R) running out of the amp, through the first coil, and then through the second coil, and then back to the amp, so each coil will have 15.8 amps running through it. If you have the same sub wired in parallel to 1ohm and is receiving 1000 watts from some different amp, you will have 31.6 amps running out of the amp, which is then split, half of which (15.8 amps) goes through each coil, so you still have 15.8 amps running through each coil. The sub will behave the exact same way in both wiring schemes, both thermally and mechanically, the only difference is how the amp is affected. And as was said above, if you have an amp running at its minimum impedance it will have similar distortion and heat buildup as any other amp of similar build quality and typology running at its minimum impedance, regardless of what that impedance actually is.

And there are a ton of VERY high end amps that are 1ohm stable: helix, brax, dls, genesis, us amps, zapco, arc, linear power....should I go on?

This is getting interesting ne way my budget is around 350$tops so let the suggestions begin. Once again the speakers say 1100rms a piece at 1ohm. So let the amp suggestions begin.

mannyb18b, first off according to your age that's listed on your profile, i have 10 years of worth of life and experience than you. so please don't be so prompt to say don't listen to a newbie. just because i have less posts than you and signed up after Jun 2004 doesn't mean i don't know what i'm talking about. i was messing with this stuff while you were still in diapers, and as i stated in my post i was speaking by experience. also i wasn't arguing with sr20. he asked a Q and i responding with an anwser. i personally thinks he knows quite a bit. we were both helping Dreamspawn come to a decision. (maybe i delt with ancient technology)

if you can why don't you list some decent 1ohm amps here for him? and when i mean decent i mean that pushes out a constant amount of power, not something that jumps like a frog? i'm sure that will help him out quite a bit. as for me i would go with a punch from rockford fosgate. although those amps are in the higher cost bracket. like i said in my post.....you won't find to many 1ohm amps out there that are really good, in my opinion (i see that sr20 list a couple)

Dreamspawn, take your advice how you want it and go from there. if you need further assistance just pm me. i'll help you out to the best that i can.

what bout the power acoustik a2400 the ed nine is nice but only puts out 1200 watts and i want to atleast put a 1000 to each. The most powerful punch i could find was 800w. Nemore suggestions? U think if emailed SPL maybe they could throw some suggestion? I know its highly unlikley but worth a try?

Ok, im not even gunna start.
To DreamSpawn- The eD nine.1 is more like 1400 watts, real true power. The nine.1 is a pure quality amp and is UNDER RATED, unlike Rockford Fosbreaks that are overrated. Some rockford fosgate amps are pretty good ill admit that, but thats about all that can be said about them. Nine.1 rapes the Rockfords, period. And Schemo, what system do u have in your car???

bumpinstang77
01-11-2005, 08:06 PM
the nine.1 runs 1500 in a decent electrical system and dude lookin for the amps I'm tellin u don't put gobs of power to them esp. an amp that's overrated and will distort easily the nine.1 and bx1800d are very nice power wise..... If you did your electrical system right that nine.1 would put out every bit of 1600 watts plus.

Mannyb18b,
i really didn't want to start anything, but i have been playing with this stuff since you were about 5 years old, but enough of that. i just bought a new deck pioneer dvh-5000mp i believe is the model number, plays dvd video, 15 band eq, 6 1/2 components on the front doors, 4-way 6 by 9's on the rear deck, 4 10'" pioneer subs in the back, two pioneer amps 2 channel and a 4 channel. nothing impressive just good enough for me. where i'm at i can't play the system loud cause it WILL get stolen in a heartbeat. i got all pioneer in my car. but now i'm planning on trying other brands.

what do you have in you car???

i will admit times has changed from when i started to today, more than half of whats on the market didn't exist back then.

i want to sell my 4 10's and get 4 12's and want to run them at 1 ohm, but not sure what amp to get? i want at least 500 watts minimum to each sub, also i would like a mono. anyone have any input??? since the old man is out of date with the times?????

A capacitor stores energy and basically just keeps the voltage across its terminals from changing instantly, that's it. After a second into a bass hit it will be discharged enough where it will be doing no good and will just be another strain on the system. Don't waste your money, upgrade the battery and magic 3 instead.
