Need help to plug my subwoofer !!!!!!!!!

guiguilandry · 02-20-2009, 10:07 PM

Well it is my girlfriend's subwoofer in fact...
it is a Clarion SRW1252 800 watts dual 4ohm voice coil....
I need to plug this to a Kenwood KAC-959 800 watts amp but this amp is 5/4/3 Channel.
It has the outputs for the speakers and they can be bridged
But it also has the output for the sub....
My question is what is the best way to plug the double voice coil to this amp.
Right now I'm not using the amp for the speakers...
Can I have more power by pluging the sub to the bridged speakers outputs or just simply pluggin it to the sub output???

And How to plug a double voice coil sub. Do I take the two + and the two - in parallel to the single connector in the sub box and it makes this like a 2ohm sub ???....

Sorry to sound like a noob in audio, but... I am one.... lol

You have to bridge it. Its hard to describe. Put the amp in 4 channel and *I think*: Chan 1 positive to sub, then same voice coil negative to negative on channel 3. Chan 2 positive to sub, then that coil's negative to negative on channel 4.

Someone correct me if I'm wrong.

I looked there before i posted lol. Doesn't have this configuration that I can see.

cool thank you, just one more question, will it be more powerfull at 8ohm or 2 ohm, my guess is 2 ohm... and whare can I find if the amp is good for 2 or 8 ohm in the bridged speaker signals or sub signals ????

they say this about this amp :
Description: When 5, 4, or 3 channels of amplification are required, the 40 watt x 4 channel + 120 watts x 1 channel KAC-959 Multi-Channel Power Amplifier is a great choice. The bridged rating is 120 watts x 2 + 150 watts x 1 for a maximum power rating of 800 watts. Features include a variable low-pass crossover, selectable high-pass crossover, and 2-ohm stability. Speaker relay protection and a quiet turn-on make this amp competition quality.

Am I better to run the two positive and negative of the sub to the single output of the sub out on the amp ??? 150W
Or to run each voice coil to one bridged 120W output of the speakers ????? or this is just not an option at all because this is just not displayed in the 12volt website and that could bust the amp

2 ohm. Less resistance means more power. Google KAC-959 specifications, it lists its power handling @ 2 ohms so its safe at that impedance. However, you should know that wiring a DVC sub up to multiple channels can be dangerous to your speaker. If one coil is pushing while the other is pulling, kaboom. Personally I would not do this.

with the given specs of the amp am I better just to let the speakers outputs alone and to simply plug it into the sub output ??? they say 120 or 150 watts ????
or to plug them on one of the two bridged channels of the speakers ??? tey say 120 watts ...

I think you would have to connect your coils in parallel to this sub output, meaning half the power to each coil. That, or power only one coil. I have never owned a multi channel amp though.
