bridging

is bridging your subwoofer really make a difference in you bass?

[Laidout69]

You can bridge the wires on your amp to get the mono power. More power can mean more bass.

ya, it makes a huge differance... i had a pair of 10s that were 10 x's louder bridged than 2 12's that werent

if your subs are dual voice coils then u can run the subs in paralell which will make them thump. That bridges the amp down to something like 2 ohm or something like that. Im runnin a 800 watt MA Audio bridged to 2ohm on 2 12" JL Audio W3V2 subs and it fockin thumps my sack harder than a chronic masterbator in prison.

ok that last mental picture was un-needed, specially since i just got hired as a prison guard

that was an awesome analogy, thanks Boz...haha

wow, that was crucial....anyway, yeah i have always bridged the amp, but i never had a dual voice coil sub. i have had a JL w0, 2 RF punch p1 10's, two 12' Kenwood tornados, and a few more i just don't remember but know i have a 12' audiobahn dual voice coil (8) ohm AW1251T and a 800 watt Kenwood amp to push. so i was wondering if that bridge on the sub to that second voice coil would really make that big of a difference.......

damn none of you guys really know what bridging is...basically you have an amp with multiple channels. When you want to combine the power from each channel into one power source for the sub, you bridge the channels. This is normally done by using the positive of one channel and the negative of the other channel. Not all amps are 2 ohm stable when bridged. Do not attempt to bridge your amp until you are positive that your amp can handle it. On most amps, when you bridge the channels it is only stable to 4 ohms.

you dont bridge a sub dude, you bridge an amp. A sub is wired either in series or parallel, you cant "bridge" a sub.

In your case with your dual 8 ohm sub, you want to wire the sub in parallel. You can also bridge your amp since the final impedance will be 4 ohms and i'm sure your amp is stable to that load.

Take the positive of one channel of the amp and wire it to the positive of one of the coils on your sub. Now take a small length of wire from that positive terminal and connect it to the positive wire on the other coil. Now you take the negative on your amp and connect it to the negative on one of the coils, then take another short peice and go to the other negative on the sub.

yes you can bridge a sub, it's the only way for both of your 4 ohm voice coils to run together.... and i think everybody knows how to bridge an amp....
