SOURCE: amp arc

What you need to do is first ground your amplifier securely then make sure all connections are fastened. don't remove the speaker connection and listen for sound. If there is no sound power down the unit, and send it to a repair shop because it sound like you may have damaged some components in the unit. But in order to come to this point you have to make sure you ground the unit properly and then make sure all of your connections are secure. Contact me once this is done and you are ready to do some tests.

SOURCE: amplifier loads

Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

SOURCE: I HAVE A PUNCH A2 AND WHEN I HOOK UP THE LEFT

If your speakers not wired up properly sometimes the bass can shake the wire off and it leads to a horrible crackly noise, make sure it's securely wrapped around and tied to the terminal. Otherwise it could be a blown speaker or you are trying to put more power into the speaker than the speaker can handle.

I have bought JAMO sub 250 subwoofer and Pioneer VSX919AH-K amp. Please advise how can I connect them. The amp has one RCA out for sub but the sub has two line in sockets (left and right). Do I need to use...


Hi,
You don't need such cable, although you can use it if you have one. If receiver has only mono SUB output (as majority of receivers have), you just connect it to the Left socket on the Sub and it will work.

Using the Y cable would probably cause that you will fed the same signal to both left and right sockets, but half the intensity (you would divide the output from receiver by 2). So in the end the Sub would receive exactly the same signal as when using normal straight cable.

Wiring for 2 subs for max performance


This amp is rated at 500 watts into a 4 ohm load bridged mono or 250 watts x 2 into 2 ohm load stereo. Do not go below that impedance in either case. The amp was meant to dissipate a certain amount of power, driving it to hard will lead to damage. Your speakers look like they are dual voice coils @ 4 ohms each. To get the max power while still saving your subs would be to parallel the voice coils on each woofer then run them in stereo with your amp. Stereo 2 ohm is 250 watts per speaker.

Ok I just bought a used fosgate amp belive its a T10001b could be wrong its big has fan 3 led lights and some pioneer premier 10 flat subs think there 4ohm. I bought a brand new amp install kit 6gauge...


eyp, most of the time speaker connections blow and fuses wont stop that from happening. They are there to stop the mainboard from frying and not working at all. try running rca splitters to the operational side of the amp. run the sub on 1 channel. you will start hearing a difference but both sides will work. if not, run the splitters from the head unit and bridging it. these are the cheapest solution i could provide

What amp do i need to power a Polk Audio db1040DVCin brigded connection, i only plan to run one sub, i want to bridge the sub for better sound quality, and i'm buying straight polk, what do i need


Hello oran1891,

OK, you don't bridge subs. You bridge amps, if they are capable of being bridged (not all are).

Bridging is a method of connecting the channels of a multi-channel amp in such a way that the amp delivers the output of 2 stereo channels into a single mono load.

The Polk DB1040DVC is a sub with dual 4ohm voice coils. You can wire the voice coils to present a final 2ohm load (parallel) or a final 8ohm load (series). The rated power range is 50-270 watts RMS. Since you can parallel the voice coils and have them present a 2ohm load to the amp, you are looking for an amp that provides a minimum of 50 and a maximum of 270 (round it up to 300) watts into a 2ohm load. The Rockford-Fosgate Punch 300.1 shown here for $170 seems tailor made for your Sub. If you can make do with less power and want to spend a little less money, the Orion Cobalt CO500.1 will deliver 250 watts RMS at 2ohms and you can buy it for $140. The punch is a better deal. If you decide to add another sub later, it will power them both with 150 watts each, a little low, but still decent. If you want a 2-channel bridgeable amp, I'd recommend the Kicker 08DX3002 shown here for $200. Note that in bridged mode, it is not stable at 2ohms, only down to 4ohms.

Hope this helps.

Speaker installment


I would run a 250-500 watt 2 channel high input capable amp.  run the original wires to the orginal speakers and jump off the original wires to the amp to push the secondary 6X9's you have.  So my understanding is.  you want the 4 original speakers and subs and add 2 additional speakers making 6 speakers not uncluding subs..
Head units care barely push 4 decent normal size speaker.  Usually they are 30-55watt per channel.  If you have 2 non sub speakers that are 250 watt max.. that's 500 total but don't push the amp all the way...start with it at 1/4 and listen to your stereo at a higher than nominal volume slowly turning up the amp.

JBL spot series speaker not working.


I know this is old but just incase anyone has the same problem. Its proabably the connection from back panel to the internal amp (Inside the sub enclosure). The ribbon cable has the + for the left speaker right at the edge with quite a bit of tension. Over time and with the vibrations from the sub this will bend/pull out slightly and needs to be pushed back on and some hot glue put around the connection to hold it in place.

Thats how I fixed mine anyway.

Punch p1 10" not working


I had the same issue with 2 Punch p1's. The wire stripping was most likely cut where the wires are saddled against 2 bare metal "C" shaped tabs before going toward the cone and coil. This was causing the wire to ground out. I cut both wires and **** connected them and bypassed the factory bracket. They work fine now. This is a poor desogn from Rockford and I can see where it might happen numerous times.

My JL subs just dont beat like the ONES IVE HAD before as well as the ones my friends have had


sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.
