sub and amp help

[ccapehartusarmyINF.(ret)]

i currently have two infinity 1260w 4ohm svc subs running on the sub channel of my 5 channel amp and i want get a 3rd infinity sub wich creates an issue
3 subs wired in parallel brings the impedence to 1.3 ohms and i figured im going to have to buy another sub amp thats 1 ohm stable so other then orion hcca what other manufacturers out there currently make 1 ohm stable amps

All 1 ohm stable amps, on the left you can select 1 ohm stable. Add all the RMS together and that is the wattage your amp should be. 1 ohm stable ofcourse.

Kenwoods go into protection mode fairly easily, MTX amps are easy to burn up.

Pioneer is the only one I truly trust there for what you need. You need 900w RMS 1ohm stable.

Goodluck, have fun, keep your hearing.

I like Crunch amplifiers. They are affordable and put out good power. Check out amazon and search the crunch 3050.1, or even the 2000.1. Great amplifiers 1 ohm stable. I run the 3050 on 4 twelves at 1 ohm with no problems and have used the 2000 watt as well. The same company also makes hifonics which puts out better power than crunch but not quite as affordable. I paid 130 for my 3000 watt amp.

well the sub channel on my 5 channel PA amp was pushing 420x1 at 2 ohms to my two infinitys i opted for pushing more power to just the two infinitys the amps adverstised at 700watts rms x1 and 1500 peaks but i figure its more like 550 to 600rms but shit idont care if they over rated my two twelves really hit hard to the point i have to turn the bass down bass boost off gain down significantly cuz its causing two much of that plastic shit in the backof my tahoe to rattle to much

There are plenty of companies that make 1ohm amps (most being Class D amplifiers)

JL Audio
Kenwood
Kicker
Etc.

Just remember, you get what you pay for. I have one 12" woofer on a Digital Designs M3B amp pushing around 3,500 to 4,000 watts to it

Yup class d

 

[NathanJax]

Yup class d

what do you know about audio?

 

[anthonyz71]

LOL that a joke right . I was at nspl world finals and was at db drag world finals were I set records.

Yup

im lookin at planet audios big bang amps 2500 watts from what ive heard ther better built then the anarchy amps
also is the jl audio jx 1000/1d 1ohm stable i was considering that one its not adv as 1ohm stable but everyone claims it works

 

[RynoHarris]

Planet audio is going to be a lot like the amps I've used. It's going to say 2500 watts but only push let's say 1900 or so. I've never heard one or known anyone with one just going off reviews I've read on them. Still good amps though. And I had a buddy that ran that jl at one ohm no problem. Jl audio makes some very quality stuff. If I had the money though for a nice amp, I'd go with Rockford fosgate. It's all quality built and tested and puts out exactly what they advertise and often times even more than that.

okay so i just said hell with it its 60 bucks i bought the anarchy 1500.1 wich i already know it says 1100watts rms its only really like 700watts rms and im running the two infinity 12s and put it this way i feel stupid for spending all that money i used to spend on high end amps one issue im having is settings i know the 2v-8v switch is right the problem is with input sens. and crossover shoudl it be set at low pass or full range now i attempted setting gain i turned deck to 3/4 volume but speakers never distorted im sure im doing something wrong baecause the subwoofer nob doesnt do anything
so right now its set roughly 3/4 gain switch is at full range no idea what the crossover cutoff freq is set to it doesnt seem like it does anything like the subwoofer knob okay does the crossover switch on either amp have to be set to HP LP not full range in order for the knob with the freqs. to work or the sub volume nob

Really dude. You need to use punctuation, and capitalization in your posts. I think you'll find you get way better results when people can understand what the hell your trying to say.

The 2v/8v switch is to match the line level inputs to what your deck can output. Basically if you have a deck that has standard outputs you'll want the 2v choice (It makes the amps inputs more sensitive for the lower deck output, but it can let noise into your system). If your deck has high outputs (4v or 6v for example) you'd want the 8v setting (obviously make the amp inputs less sensitive, but lowers your possibility of unwanted noise). Your crossover tells the amp what frequencies to ignore/amplify. High pass causes the amp to ignore lower frequencies, and play higher ones. What that cut off frequency is may be adjustable, or it may be fixed. Obviously if it's adjustable you will see the switch/ or knob to do it. A high pass setting is typically used for your main speakers when you also have a sub because it keeps the lower frequencies that are harder for smaller speakers to play from getting to them which lets them play louder without distortion. A Band Pass setting lets the full range of frequencies to your speakers for when you don't have a sub. So you can hear all the frequencies of your music. The Low Pass setting is for your sub-woofer. It directs only the lower frequencies to the sub so your not wasting power trying to play frequencies from your sub than can easily be handled by your main speakers. Gain. I would say there are as many ways to set gain as there are opinions. Really the absolute best way to set gain is to use an oscilloscope to measure each of your components output watching for distortion. Really though unless your in competition I would call that overkill. How I like to do it is turn my deck about 3/4 the way up and then slowly bring up the gain until either I can hear distortion (which then I'll back it down a bit), or the volume level is as loud as I would think I'd ever want it. Then at the same setting (3/4) I'll bring up the sub gain to (again) either distortion, or as loud as I'd ever think I'd want it. The thing to remember with gain is you want it as low as possible. The higher the gain the more easily the amp can/ or will pick up noise. (Now you didn't mention it, but I will explain it for your knowledge.) Slope is how aggressive (or how quickly the sound will drop off beyond the setting) the cross over will be at the set frequency. A 2dB slope will be less aggressive than say a 4dB setting.

I don't know the specifics of that particular amp, but typically all a sub knob does is raise/lower the gain to set points above-below the main gain setting. A bass boost knob may do the same thing, or it may boost a certain frequency range to accentuate those frequencies.

okay i think i got it figured out i had all channels set to full range it kinda felt like to much bass was coming outta the door speakers so now all the freqs go were theresupposed to go now the gain on the mono sub amp deck at 3/4 volume started turning the gain up goes all the way up no distortion now when i started turning up bass boost then it started getting loud and then distorting and this is all mute point cuz i sent back the planet audio anarchy 1500 watt and replacing it with the axis 1500 watt i guess that product line is rated more like the big bang series

 

[scoobyxj]

Yeah. when you set your sub gain turn the sub knob all the way up. That way you can set the upper limit to play without distortion. Then you can just use the know to turn the amp up or down according to your taste...
