OK im running 2 audiobahn 2000 watt subwoofers so 4000 watt total. I have it running at 1 ohm and i want it louder so it says at 1 ohm it runs at 1000 watt x2 and with 1/2 ohm it runs at 1500 watts x2 the guy i talked to said i had to wire the amp and subwoofers parallel what does this mean. Also if anyone has a boss pd3000 cuz thats what im using what bass settings are the best for optimal performance
By the wya im running 2 audiobahn 12qs 2000 watts each and a Boss pd3000 3000 watt amp

Just what are you using to power the amp? Do you have HO alternator? Without adequate power, it won't do any good.
Is the sub ported or sealed? for SPL, you will want ported box.
One more thing, Boss amps aren't known for their quality. I wouldn't push it a 1/2 ohm. If you need that, try Orion HCCA 275 G4.
Wiring subs in parallel means connecting the pos to pos and neg to net on each sub and then wiring them together the same way in parallel (pos to pos and neg to neg).

what should i do because i should be pushing alot more than i am i have just a regular alternator and battery could this be affecting how much im pushing? and how would i wire it to 1 ohm becuz i dont know if its done correctly

Well what is the spec of your subs? Is it 4ohms DVC or SVC?
For 4ohms DVC, wiring in parallel will drop each sub to 2ohms, then wiring them in parallel again to each other will put it at 1ohm.
A stock alternator will supply around 75A the most. So your 3000w amp is getting ALL of it's power from the battery which is 12v. This is probably why you're not getting lot of power.
You need to get HO alternator first before wiring the subs to 1ohm. If not, you will surely kill your car.

I'm doing around 3200 watts with an extra Optima yellow top bat. and an AlumaPro 15 farad cap. bank. Under my hood is a stock bat. and alternator. I have no power probs at all, NONE!!!

a: that capacitor is totally useless. it does nothing for voltage drop. It also has a horridly high ESR which makes it even more useless for any car audio application. great gimmick though. makes alumapro lots of money from those who know nothing about electrical engineering or the basics of what a capacitor actually does.

b: if you have a stock alternator and charging system, you're NOT drawing anywhere close to the power you claim. You'd be lucky to get 500 watts from that system without dimming lights and a stalling car.

the pd3000 is capable of putting out it's rated power at something like one-half own, but at higher loads it puts out a mere fraction of that power. since you won't answer anybodys' questions about your subs and their coil configurations, nobody is going to be able to tell you how to get full power from your low end gear. you have some potential with what you have, but it has to be put into the right box, installed properly, and set up well to get any performance out of it.

probably "3200 watts" max, not RMS.
I can guarantee you there's no physical way possible you'd draw 3200 watts worth of current from a stock 12VDC charging system in a car while the engine is running.
That yellow top would last you about 5 minutes before it gave out at that much draw, too with the motor off.

you want the amp crossover set to "low pass" and bass frequency is probably for bass boost EQ, which is best left flat or at zero for now while we get the rest of the system worked out.
set the LPF to 80Hz

I Have 2 Ampman/Adire class D amps rated at 1500 watts RMS each at 1 ohm.
I have 4 Farenheit CK12" subs rated at 1000 watts RMS each wired in a 1 ohm load. Each sub is in it's own 1 cubic ft. sealed chamber made out of 1" mdf and another half inch of Dupont Corian on top of that for the face of the box.
Top end Cerwin Vega componets up front and Infinity 2 ways in the rear that are being run by a Profile Clarus 4 chan. amp. And again a 15 farad cap bank and an extra Optima yellow top, along with the stock bat and alternator under the hood of my 97 4Runner. All going to an Alpine deck. I have had it in car shows and when people feel it and hear it they are in awe!

I also have in the 4Runner:
2 Nesa 6" headrest monitors.
1 17" Dell HD widescreen.
1 XBOX.
1 1750 watt power inverter.

And yes I look for the RMS ratings on electronics that is why I will only buy Onkyo,Denon or Yamaha for the home. The Onkyo is working great with my Velodyne Sub.

http://jlaudio.com/tutorials/wiring/index.html#2dvcsp that is how to wire your subs to get a 1.5ohm load you will be getting about 750 Boss watts to your 1000 watt audiocrap subs. What that evens out to be is about 300watts(true) to your 400watt(true) subs it should sound ok if that amp is even really stable half as low as t says it is which I highly doubt it.

Oh im at least hitting 1200 watts right now having it wired to 1 ohm i think i just need a new battery and alternator if i just get an Optima battery i should be set shouldnt I and would your cd player have any affect on loudness and bass and stuff and whats the best Cd/Mp3 player out there right now
