SOURCE: Rockford Punch HE2 wiring question.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

SOURCE: need to wire two dvc 15 in kicer l7 to 1 ohm

Hello goldy6569,

To wire the L72's at 1ohm, simply connect both +'s and -"s on each sub together. Then connect to your amp terminals.

With 2ohm DVC's, you can have either a 1ohm load or a 4ohm load. The diagrams are here (I know it's the website of a Kicker competitor, but their "wiring wizard" is simply the best).

Hope this helps.

SOURCE: Want to bridge 2 channel amp to push single 4 ohm dvc sub

Hello k_rabbit89,

A 4 ohm DVC sub can be wired in series like you described for an 8 ohm load or the voice coils can be wired in parallel for a 2 ohm load.

If your 2-channel amp isn't stable down to 2 ohms when the channels are bridged (most 2-channel amps are only stable to 4 ohms when bridged), you do not want the voice coils paralleled. The amp will overheat, go into protection mode, and eventually fail completely. A sub with 2 ohm voice coils would be a better fit. That way, you could series the coils for a 4 ohm load and the amp would operate OK with the channels bridged into that load.

But anyway, for the best power from THAT amp to THAT sub, your best wiring solution would be to wire each voice coil to a separate channel. The problem with that is that the signal to each coil needs to be EXACTLY the same or you will have one coil trying to move the cone out while the other one tries to move it in. You can closely approximate identical signals on the output side by using the same input to both channels. Do this by using only one RCA connection (either right or left channel) from your head unit and split it with a "Y" cable.

Hope this helps.

SOURCE: i want to know the best subwoofer wiring diagram

if the amp has a 2 outputs then i would wire the two 4ohms together, and the 2ohm by itself. and if its a 4 channel output then wire them all sepretly, if its a 1 channel output then wire the two 4ohms together and leave the 2ohm sub out

I got 2 10in kicker comps and the rms on them each is 150 watts and can i hook them up to a 1000 watt sony xplod 2 channel amp and do i use both channel or just one or bridge them


1st thing is amps outputs have to be properly "loaded" this value is given in "ohms" if your amp says minimum speaker "loading" impedance is 4 ohms ( I suspect it does) then you may load that 1 channel down to only 4 ohms or amp will be damaged , most speakers are rated in ohm's Impedance (look for Greek symbol for omega) look for its rating somewhere on it doing the electrical formula math if you connect two 4 ohm speakers in parallel to one channel ( +=+ / -/- ) this divides down to 2 ohms (not good) but if you take same speakers and connect in series together (+to-/+to-) this gives you eight ohms (better) , the watts rating is a figure for you to determine the amount of power the speakers will take before failure , hence just because you connect 200 watt speakers to a 2000 watt amp is no indication that speaker will take all 2000 watts ( it will fail long before that point ) watts do ADD together like the above example two 4 ohm 250 watt speakers connected to one channel of amp in series will look like ONE 8 ohm 500 watt speaker to amp of course over 16 ohms load speaker volume will greatly diminish and amps have max impedance loads for them as well although there not often published
this is why I love the old TUBE!!! amps they load all the way down to 2 ohms and go up as far as 32 ohms load with no problems , they sound better as well across the board as well

The ampe i got is the bp1200.1 is that 1200 watts in to one chanel can you tell me thanks


it is a mono (one channel) amp. it outputs 600 watts at 4 ohms (1x4 ohm speaker connected) and 1200 watts at 2 homs (2x4ohm speakers or dual 4 ohm voice coils in parallel).

Been looking everywhere for this... i just hooked up my PMP6000 to my brand new JBL EON's 305 (non-active), stereo (one cable for A and B) using Speaking to 1/4" cable. My output level was also VERY...


The JBL EON 305's are 8 ohm speakers. The PMP5000 wi;; produce 400 Watts per side into a 4 ohm load (600 Watts peak). Into your 8 ohm speakers, the peak current will be halved while the voltage remains the same so you ACTUAL power per side is 200 Watts. It is hard to know how much you expect to get out of the amp. This power would fill a venue of at least 2000 sq ft. If you need more sound, try borrowing another 8 ohm speaker for each side and parallel them with the EON's as a test. That will double the power and add 3 Db more of sound. Your main slider should be around unity typically. This amp is a class D switching type (very efficient) and runs on +/- 70 volt rails. giving about 45 volts RMS output. At 4 ohms, this is just over 10 amps giving 450 Watts... at 8 ohms this is around 5 amps or 225 Watts.


Please read my tip on Fixya about the ground hazard of channel A when using 1/4 inch cables out of the PMP units... essentially the BARREL of the connector from channel "A" is the HOT,... NOT the tip of the PLUG. Ground the barrel IN ANY WAY AND YOU FRY CHANNEL "A" AMP !!!

Can I hook up 2 lanzar opti1532 subs 2 a kicker kx 1200.1 or do I need a bigger amp, its a 1ohm stable amp an birth sheet says 1390watts but they told me at 14+ volts it will do 1400rms


Based solely on spec sheet information the Lanzars can handle 1300 watts RMS and the KX1200 is rated at 300x1 @ 4 ohms, 600x1 @ 2 ohms, & 1200x1 @ 1 ohm. Even with a 1 ohm load you will still only be providing 600 watts to each sub. While the kicker will provide more power at 14+ volts, no car creates more than 12-13 volts via its alternator. A car battery only provides 12.6 volts. So you will be loking at 1200 watts from 1 channel as a best case scenario.

Additionally, with your 2 subs, they will need to both be Dual 4 ohm voice coils in order to net a 1 ohm final load. Each voice coil will need to be wired in parallel and then each speaker needs to be wired in parallel.

What size amp needed with a sony explod player?


this bandpass enclosure is rated peak power at 1200 watts . what this means is that each subwoofer in the is peaked at 600watts to make 1200 watts . what your looking for is to power up the subs with rms continuous wattage . you need an amp that will put out 400 to 500 rms a channel to run this sub enclosure at 800 to 1000 watts rms to keep the speaker from blowing


audiopipe apf1801
71671968.jpg this amp will give you 1 channel @ 4 ohm x1 350 watts 1 channel @ 2 ohm x1 900 wats 1 channel @ 1 ohm x1 1800 watts you would have extra power for better subs with more power later but you get 900 watts which when connected right would mean 450 watts per sub be perfect for you . i sell this for $320.99 in my store can shipp any where in usa to contact me caraudioquestion@gmail.com

I have a 12 inch audiobahn 550 rms 4 ohm coil ported box and a dual box with 12 inch subs they say 550 max wattas a piece thats it waht amp do i need to get atleast 80% of my power in bass


Get a 1200 watt 4 channel amp that's 2 ohm stable. Bridge 2 channels into the single 550W rms audiobahn. Use the other channels for each side of the dual box. Turn the LPF or Low Pass Filter on and vibrate down the road.

XM-2002GTW Car Amp: i have 2 dual 2-ohms solobaric speakers and im try...


I researched your amp and it looks like its not even 2 ohm stable :( the problem with these companies is they lable there amps 1200 watts MAX, that means they tested the amp in a perfect enviroment and the amp fried somewhere in the ball park of 1200 watts, your best bet is to save your money and buy a nicer amp that is two or one ohm stable... that being said the best way to wire your subs is in series
