Question about Car Audio & Video
Connect ampere in parrel way . connect it in parrel, an run ur power wire to ur battery (red wire) ur power turn on lead an rca cables to ur cd deck, ur ground wire (black) to a solid ground, any slid metal in the car . run ur speaker wires negitive to negitive terminial of the amp an positive to positive in parallel.
Just run the positive terminal from one channel of the amp and opposite channel's negitive terminal to one sub. Run the 2 remaining terminals (the positive of one channel and the negitive and the other) to the other sub. That is how you bridge, but then how you acutally connect to the sub depends on how you want to wire (series or parallel). If they are DVC subs (dual-voice coil: two pairs of positve and negitive terminals on an individual sub), then it's best to run in parallel to get the post power. To do this, individually hook each bridged channel separtly to one pair of the +/- terminals on the sub, then from that run more wires to the other +/- terminals on that sub. Do this separatly on each sub.
another way is -------- Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,
This will create a 4 ohm load on your amp.
Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms. Bridging a 2 channel amplifier when using two subwoofers will supply the same amount of power to each subwoofer. It will simply be divided from the 2 channels wattage , then supplied to your two subwoofers. To bridge an amplifier, if it is a 2 channel, you would take a positive and a negative from each channal and wire them together making 2 positive wires become one positive wire and 2 negatives wires become one negative wire (twisted together); then connecting the positive to the far left (channel 1) of your amplifier, and the negative to the far right's negative terminal (channel 2). You need to make sure that the impedance is going to be stable once bridged too. Usually a dvc 4 ohm subwoofer pair can be wired series/parallel to establish a final impedance of 4 ohms bridged. check out.

Hello their, I have reviewed your post about the 4 Channel Power Acoustik 1600 Watt amplifier not going out of protection mode, it's a class a/b amplifier so it's porbably best not to run it in bridged mode 2 Ohm Stereo, 4 Ohm bridged. this amplifier has overload as well as overheating protection. a quick test to check that the amp is working properly is to take a jumper wire from the power side of the amp, and connect it temporarily to the remote side, this is only to test. if you left it their it will drain the battery as the power on the stereo remote wire turns the power on the amp when it is powered. another thing that happens is that the ground looks like it is good but theirs so many factors at play with a good solid ground. the misconception is it only needs to be connected by a thread. meaning 1 or 2 strands of wire, not true at all, the negative cable is very thick often, this is because the power flows threw the ground as well so it would be very wise to check that the ground is connected to the chassis. something else that will help you is to test only one side the the speaker at a time. meaning of course hook left or right up to the amp and see if their is anything. sometimes the speakers are wired in series if this is the case then that will not work, but it may prove that the amp was wired from say positive terminal to negative and causing an interanl fult protection circut to cut the power to the mosfeats before they overloaded. theirs a verry good chance from this description that their is a + speaker wire going to a negative terminal with 2 speakers. low-impedance loads will cause issues say short circuits or backwards wiring. they can happen and not even be oblivious till you look at the speakers configurations.

You are doing right on what you described. I really like to work with a clearly described what involved in an issue.
Now we have to use a Voltmeter to check if there is power to the amplifier. If there is power to the amplifier terminal, then the problem is at the amplifier, not the connection. Let check it out:
1- Turn on your Kenwood radio, make sure to hear sound from your regular speakers.
2- Turn remote control knob to the mid level between min and max.
3- Measure the blue wire where you spliced to ground to see if you have 12V, if it is not then the problem is right there.
4- Measure the Red wire power from the Amplifier to ground ( the bolt that you connect the negative power to see if there is 12V, if not trace back to the Fuse that you inserted between the positive terminal of the battery and the wire going through the firewall to correct it.
5- If you have 12V at step 3 and 4, then you have a defect unit, return it to the manufacturer for a replacement.
