There are a couple different ways you can wire up this speaker as it is a DVC speaker. Duel Voice coil, it has two + post and two - post. A dual 4-ohm voice coil subwoofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you'll get the most output from your amp.
Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance.
You can wire each voice coil to a separate channel of your amplifier, if you prefer not to bridge your amp. Independent wiring is a nice option if you're wiring two DVC subs to a 4-channel amplifier - one voice coil per channel
Depending on what you are hooking it up to i.e. a mono amp or a bridged four channel amp. I can tell you post to wire exactly if I know how you want to hook it up and what ur hooking it up to.
OK. Sometimes manufacturers put two flat prongs to each of the positives and negatives of the voice coils. This allows for daisy chaining multiple subs to be easier. Here is how you want to wire your subs in the box.
From the positive post of the box to the positive posts of both voice coils (just choose one prong on each of them, you do not have to connect all 4 of them). So you will have 2 wires going from one post on the box to 2 posts on the sub. Got it. Not go from the negative post on the box, to both negative posts on the subs. Repeat this with the other sub. Now you can hook each channel of the amp to the box regularly pos of amp to pos of box and neg of amp to neg of box.
This set up is called parallel and will drop the ohms resistance of two 4 ohm voice coils to a 2 ohm load. You will get 2 ohms for each sub, thus connecting one sub to each channel. This will allow you to get the max power out of the amp or 150w RMS per your post. Hope this helps.
First of all.
Using two different kinds of sub woofers, is not an option, as these two sub woofers have different specifications and you should never mix sub woofers.
Now the better choice from the 2, would probably be the Rockford. (cant be sure without knowing the models, power handling is also a factor in how well either of the sub woofers will play, but Rockford as a rule makes better sub woofers than Sony does)
In my opinion, both the sub woofers deserve a better amplifier than what Boss has to offer.
However to connect either of these sub woofers, you would need to determine how many voice coils it has and how many OHM the voice coil/s are.
If it is a DVC (dual voice coil) and each voice coil is 4 OHM or 2 OHM, then you can connect one voice coil to one channel of the amplifier and the other voice coil to the other channel of the amplifier. If it is a DVC 2OHM you can also connect it wired in Series/Series to give a 4OHM load and should be connected to the BRIDGE dedicated speaker outputs of your amplifier.
If it is a SVC (single voice coil) and it is 4 OHM, then you can connect the sub woofer to the designated speaker outputs of your amplifier that states BRIDGE.
DO NOT run the amplifier in BRIDGE mode at 2 OHM as this will probably damage the amplifier.
Well i tried looking up that amp, but Fosgate sight is down. So assuming that the best power out of your amp is 2ohms off the bridged hookup, and the subs are 4 ohms per coil, the best way is to only use one side of each speaker and hook it straight the the bridge. Only using one hook up wont hurt anything, its just for giving you wiring options. And when adding up ohms of speakers, it goes like this. If you had two 4 ohm subs, that'll give you a 2 ohm load. If you hooked up all your hookups, it would be like having four 4 ohm subs, and would give you a 1 ohm load.
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.
Your PSW815 has 2 ohm dual voice coils allowing you to better match the impedance to your amp. Each voice coil is 2 ohms. If you wire them in parallel (both +'s together and both -'s together and then to the amp terminals), the sub presents a 1 ohm load which is too low for most amps. Wiring the voice coils in series (one + to the other - and the remaining + and - to the amp terminals) results in a 4 ohm load.
This link shows the wiring diagram for both options. If you know for sure that your amp is 1 ohm stable, use Wiring Option #1. If the amp is not 1 ohm stable, use Wiring Option #2.
Well, this means you have dual voice coil subs. These subs are for running one sub in stereo mode( meaning you can hook up a right and a left channel to one speaker). In your case you are using 2 subs, which all you have to do is run a jumper wire from one side of the sub to the other. Take your (+) and hook it up on the (+)on one side of the sub and take your (-) and hook it up on the (-) on the other side and run a wire from the remaining post to the other. And do the same thing on the other sub.
In short yes. And is very common even has its own term called bridged. Taking two channels and making them one. I would hope that you are running a cap. that's going to put out a lot of power and stress on your battery
