SOURCE: bridging 800a4

That all depends upon whether or not the sub you are running has dual voice coils or just a single voice coil. The 800a4 is a four channel amp; thus the only way you can bridge it will be 3 channel or 2 channel. If you are running a dual voice coil sub then you can wire the amp two channel and get 400 watts x 2 @ 4 ohms. Make sure that you sub can handle this kind of power though.

Here are the specs:
4 x 100 @ 4 ohms (13.8V - <0.05% THD)
4 x 200 @ 2 ohms (13.8V - <0.10% THD)
2 x 400 @ 4 ohms bridged (13.8V - <0.10% THD)
Fuse: External 60A

SOURCE: want to bridge my alpine 3555 amp to run my sub.

I'm assuming this atleast a 2 channel amplifier all you need to do is hook the negative side of the speaker wire coming from the sub to the negative channel one. and the positive to another positive on channel 2. Should indicate on your amplifier channel one and two. most amps provide a diagram right on the amplifier over top of the speaker inputs. let me know if this helps.

SOURCE: I Have a Sony Xplod 800 watt amp and 2 12 inch Sony Xplod subs

You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.

Sub woofer automatically turns off when playing


Could be a number of things. First try another sub, your current sub could have a problem. Second could be to low ohms going to the amp. Is it a new install or was your current setup playing fine then your current problem happened. I need to know what kind of amp and sub and how do you have it hooked up. If it's a 2 channel amp and your running it bridge mode then the amp needs 4 ohm sub hooked up unless specified that it can except a lower ohms. Could be a voltage problem as well. You can contact me at skinnman33@gmail.com let me know if this helps.

Which subs to use with the rf punch 8002


You should get the dual 4 ohm version of subs and wire them both in parrallel and series for a 4 ohm load to that amp, Bridge the amp and your subs should be seeing about 960 watts true rms.

Overheating amp problem...easially fixed, i think....


depends on the sub rating.

if subs are 2 ohm rated you can ONLY get 1 or 4 ohms..
2x2=4ohm series
2/2=1ohm parallel

if subs are 4 ohm rated wire in parallel
4/2=2ohm

look it up google for diagram if you need one.

Kicker 8 inch 4 ohm subwoofer 200 watts rms?


Max 200 W. You could bridge 2 channels of a 4 channel amp (or get a 2 ch amp and bridge it) and connect the sub. Bridging = connect + of sub to + of one channel, and connect - of sub to - of *other* channel. Check amp manual for instructions.

Don't get a mono - most are 300W or more - might burn the coil during loud passages.

Two terminals? bridging theory?


Hello again jm129852,

Having two power and ground terminals allows you to run two smaller wires instead of one big one. It's a convenience. No, you do not have to use them both. They are connected together inside. Yes, you should still use a single fused battery lead. Connect the big wire and fuse holder to the battery and to a distribution block and run the smaller wires from the output side of the distribution block.

When you connect the outputs of a two channel amp to two separate speakers, each speaker gets the power produced by it's channel only. If you are using only one speaker, and the amp is rated to operate bridged, then the speaker will receive the power from both channels, typically twice as much. You do need to be careful when using bridged mode because many amps will only operate safely at a higher impedance when bridged. For example, when operated with both channels connected to separate speakers (not bridged), it may be stable to 2 ohms. But when you connect both channels together (bridged), it is only stable to 4 ohms. Usually, the specifications will tell you the lowest impedance at which the amp should be operated. The specifications for the current RF Punch 500.2 are like this: 125 watts X 2 at 4 ohms; 250 watts X 2 at 2 ohms; 500 watts X 1 bridged at 4 ohms (4 ohm stable in bridged mode). You would NOT want to connect two 4 ohm subs in parallel to this amp in bridged mode. It would result in a final 2 ohm load and the amp would overheat and fail. One 4 ohm sub would be OK, and it would receive the full 500 watts as stated in the specifications. You could connect four 4 ohm subs, two each in parallel to each channel, and the 2 ohm loads on each channel would be OK. Or you could series two of them together for an 8 ohm load, do the same with the other two, and then parallel the two 8 ohm loads for a final impedance of 4 ohms and connect them into the bridged terminals. With DVC subs the connection possibilities get more complex. There are many good impedance calculators online that can help you determine the best wiring solution for various amp/sub combinations. I like the one above at the12v.com web site. Rockford-Fosgate also has one which allow you to select the a number of subs (up to 4), their voice coil configuration (single or dual), and the voice coil impedance. The RF calculator then shows you what configurations are available and what your final load impedance will be.

Hope this helps.

Kole amp in protect mode?


Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.

Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.

Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.

Rockford Fosgate 800a2 To 2 SVC 2ohm subs


Ok.. Bridge the two sub into 4ohm than bridge to amp.


So. this how it goes.

sub1 + -
to      | |
sub2 - +
=      4ohm
       

           From Sub
                Two
            -          +  
            |           |
amp (L) - + (R)- +


This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.
