how to bridge an amp??

[pvv104]

hey everyone, need major help here..

I have a Jensen xa2100 amp, 200 watts. I just got a single 12 inch Jensen tornado sub, 700 watts, 150rms.

i know its not crazy bass or anything, but it was free so i'll take it. i have everything wired, but am not sure how to best hook up the sub to the amp...does have two negatives and 2 positives for 2 subs, but i'm only going to be running one sub, i need my trunk.

so what is the best way to do this, should I bridge it to get the 300watts x1 or should i just wire it up regularly? If bridging is the way to go, how should I bridge it, i'm not sure which negative and which positve go where. i already checked online and it is a bridgable amp. and if i were to hook it up the regular way, i believe than its 100x1, does it matter which positive and negative it should go in? i assume not. and what the heck does 2 ohm and 4 ohms mean?

Any help is appreciated, thanks,

Peter

it all depends on the sub... thats what 2 and 4 ohm mean. that is the resistance of the sub. depending on how you wire it, you can get the different resistance. i would look at the manual for the amp to see what wires go where, cuz yeah it does matter. that way you can see how much power you want to use. i'm sure you can find the manual online.

look at the actual amp, at the speaker terminals. See if it says bridged if so follow its instructions. If not x2 on finding the owners manual, go to http://www.audiovox.com and click on the jensen link
