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

If you have two subs to connect, place the speakers next to each other face down, you will notice that the connection points run in sequence +- and +-. Now connect the - (negative) from the one speaker, to the + (positive) of the other speaker. Now connect the open + from the one speaker and the open - from the other speaker to your amp.
If you have only one speaker it should be bridgeson your amp.
Your amp should have a bridging indication. On the connection points of each channel on the the amp, you should see a mark pointing to the first - and the last +. That will be your bridge

Hi, if you wire all voice coils in parallel, you will get down to 1.5 ohms. That is the lowest you can go with these 2 subs. Just hook the amps' positive to all 4 positive speaker terminals and the amp negative to all 4 speaker negative terminals. Please let me know if you have more questions, and thanks for using FixYa.

I have a power acoustik 0V4-1200 amp and 2-12" kicker cvr dual 2 ohms. My amp keeps getting really hot and turning off. I have two pair of rca jacks from my cd player to the amp. One speaker hooked up...


i have found the specs to your amp. 1. Amplifier connections: Lets make things simple. As we look at the amplifier speaker connections, we will number the outputs 1 2 3 4 from left to right for the top connections and again 5 6 7 8 from left to right for the bottom connections. 1 should be connected to a positive (RED) (+) on sub woofer A on voice coil (a) 4 should be connected to a negative (BLACK) (-) on sub woofer A on voice coil (b) Now using a small piece of cable, connect negative of voice coil (a) to positive of voice coil (b) Follow the same procedure for the other sub woofer using 5 and 8 as 1 and 4 This configuration should make the amp run at 4 OHM BRIDGED x 2. i hope this helps. dreamsystems

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 3 hifonics zeus Size: 12 inch Impedance: Single 4 Ohms Peak Power Handling: 800 watts RMS Power Handling: 400 watts Sensitivity: 89.9 dB Aluminum Cast Basket American Spider For Reliable Performance...


Hello king3132,

Three 4 ohm subs can be wired parallel for a 1.34 ohm final load or series for a 12 ohm load. If you have the channels of the amp bridged, I hope that the subs are connected in series because the Sony XM-2200GTX is NOT rated for or stable at 1.34 ohms. It's only stable down to 4 ohms.

You definitely will not get the maximum potential of the subs from that amp. They can handle 400 watts RMS each (total 1,200 watts) and the amp is only capable of 500 watts RMS into 4 ohms (less at higher impedance), so each sub could only be getting a maximum of 166.6 watts RMS.

Hope this helps.

Sub+amp configuration


With a single 4-ohm subwoofer, usually the best choice is a 2-channel amp that can be bridged to a single channel. In your case, the sub is rated for 1000 watts. Not many amps are rated for that kind of continuous power into a 4-ohm load. Kicker doesn't list a minimum power rating, which isn't unusual in subwoofer specs. Depending on your budget, I'd look for an amp rated for 300-500 watts minimum; the higher, the better, up to 1000 watts. Most amps will have several power ratings, based on the load impedance and number of channels driven. A typical 2-channel amp might be rated like this: 150 watts x 2 channels at 4 ohms 300 watts x 2 channels at 2 ohms 500 watts x 1 channel at 4 ohms. The power rating you'll want to look at will be the 1-channel, 4-ohm rating. You can look at mono amps, too, but in the power ranges you're looking for, a 2-channel amp will probably give you the best value. However, if you can find a mono amp with a high enough 4-ohm power rating, it would run cooler and might last longer than a 2-channel amp with comparable power. When looking at mono amps, you'll find their highest power output will be at 2 ohms or 1 ohm; make sure you're checking the 4-ohm rating when making comparisons. Some amplifiers that might work well for you: Kicker SX900.2 Kicker ZX850.2 Alpine PDX-1.1000 Rockford T600-2 Hifonics ZXi 1006 Premier PRS-D2100T Power Acoustik OV2-2200
