Question about Rockford Fosgate Punch 301S Car Audio Amplifier

Blowing fues trying to hook up my two 4 ohm subwoofers in bridge and in a parallel hook up for more power. but it keeps blowing the fues when i turn it up all the seting are right i put it in mono i dont know why if i hook it up two the two chanel it works fine do i need 2 ohm subs?

When you put two 4 ohm speakers together in parallel you are making a 2 ohm speaker load. (If they are dual voice coil speakers then it is a one ohm speaker load.) And when you then bridge the two output channels together, then your 2 ohm load will act as a ONE (1) ohm load to each channel since they both share the load. This is not a good thing for an amp that is most happy with a four ohm load. It will fry your amp. You are lucky if it is only blowing fuses. Or else you have already blown the amp and now it doesn't matter what the speaker load is. Try turning the amp on with NO speaker attached and if it still blows fuses then you have a amp in need of repair. Good luck.

Are you sure you can put a 2 ohm load on this amp? Thats almost a complete short.

How do i wire alpine swr1243d subwoofer

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.

Do you bridge a 850.4 four channel amp when it is 2 ohm stable and ur subs are wired up as series/ parallel and there 2 ohm dual voice coil speakers

If you wire 2 ohm dvc speaker parallel that would give you a 1 ohm load. If your amp is only 2 ohm stable that would not work. You would have to wire the speaker in series giving you a 4 ohm load. Then you can bridge the 4 channels into 2 with each speaker running at 4 ohms.
If you want to run a 2 ohm load use all 4 channels on amp and speakers. No need to bridge.
For 2 ohm DVC:
Parallel = connect both + and - together. = 1 ohm
Series = connect + from 1 channel to - from the other channel. = 4 ohm.

I have to hook up 4 amps in my car. 4 channel 700 watt ken wood, 2 channel 800 watt Sony, 4 channel 740 watt Jensen ,and a 2 channel Rockford fosgate. Which is best way to hook them up so I'm not ki

Pace posted on Saturday, March 05, 2005 - 01:08 GMT 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.

When i turn my two 12" kicker l7 up they cut out

You could be having an amp overload condition. Make sure your speaker impedance matches the amp specification. Esp if you have bridged the Amp the impedance should be at least 4 Ohms and not below. When you connect two 4 Ohms speaker in parallel the total impedance becomes 2 Ohms !!!.

I just bought an '02 Honda Civic SI hatchback that

you have to understand impedance to do this. how many ohm are your 12,s`? you can run all 4 subs in mono off one amp if wired right. it works like this, lets say all 4 of your speakers are 4 ohms. if you wire 2 4 ohm speakers in a series it looks like one 8 ohm speaker to the amp. if you wire them in parallel the amp sees it as 2 ohms, ps most amps cant handle less than 2 ohms in sereo 4 in mono bridge. so no if you take one pair say the tens run them in series now take the 12 run them in series. now take and parallel both sets to amp and you have a 4 ohm load. to better understand do a google search for series parallel circuits. also you amp should be marked for bridging if not look up the amp on the manufacturers web site most will let you download the owners manual for free if in doubt about your amps ability keep it at or above 4 ohms

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.

Ok . i have a pair of crossfire subwoofers, @

Your amplifier is 4 channel... and only 2 ohm stereo capable.

You will get the most power putting 1 subwoofer wired in parallel on each BRIDGED channel.

This will give you a 2 ohm stereo load.

Both + on 1 subwoofer to + terminal on amplifier bridged channel 1
Both - on 1 subwoofer to - terminal on amplifier bridged channel 1

Both + on 1 subwoofer to + terminal on amplifier bridged channel 2
Both - on 1 subwoofer to - terminal on amplifier bridged channel 2

You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.

Amp Problems

You are probably presenting too low an impedance load to the amplifier. In bridged mode the amp must be connected to a minimum 4-ohm load. If your subwoofer is a dual voice coil type with 4-ohm voice coils, you cannot wire the voice coils in parallel and connect it to the bridged amplifier. If you have a sub with dual 2-ohm voice coils, you can wire the voice coils in series and connect it to the amplifier in bridged mode. To connect voice coils in series: Connect a wire from the negative terminal of one coil to the positive terminal on the other coil. Connect the unused positive and negative terminals to the amplifier's output.
