I thought i'd ask here instead of making another thread. Is there any advantage to overpowering a sub? I'm going to be aiming for a Nine.1 and a 13O.v2 (http://www.edesignaudio.com) and was wondering if pushing 900w's to a 600w RMS sub would be a bad idea. I read somewhere on here that it's not a bad idea to give a sub double (or almost triple) its rated RMS power. Want to confirm.

 

the rule of thumb is overpowering by a lil bit more power is okay. a couple hundred watts maybe. it is prably better even. but going overboard is going to kill ur sub. double or triple the power is going to blow ur sub for sure.

 

pushing 900w into that sub is a really really bad idea if you look at the power rating chart.. 900 is pushing it imo. as the page says, its safe to run but it will wear out your sub alot faster..

I'll just run the Nine.2x then and save some money then. I was originally going to buy it, but the Nine.1 had more power, the attentuator ****, and greater efficiency.

So, another question, how do you bridge channels? Trying to figure out some of this stuff is making me feel like this:

Also, do you need to attach a ring terminal to all wires to connect them to the amp, or do the terminals on the amp simply screw down onto the wire? Stupid, but I can't find any answers, or even close-up pictures to answer me.

 

you can set the amp so that the sub never ever sees close to 900w.. might as well go big or go home

 

You don't have to use connectors when connecting to the amp, but I'd recommend it. It will be a strudier connection and also look better. I usually use the connectors that have to prongs sticking out that slide on either side of the mounting screws. You can get them at any hardware store.

 

most amps (i'd say 90%) bridge by connecting the left side + and the right side -. the other 10% of the time its the left side + and right side +. try the 1st one and if it doesn't work then try the 2nd one.

 

to connect the wires i like using a banana plug if not that (because its sometimes short) i solder the tips so that they stay together.

 

I'm going to be running a Nine.1@1ohm on my 13Ov.2.... as long as you're experienced in destruction of subs and know what to avoid, you can run much more than RMS on almost any sub...


the RMS of a sub is the thermal power handling. This is measured with sine wave tones played for "X" amount of time. The mechanical power handling of a subwoofer is usually much greater than the thermal handling and is what can be used if you've got the experience to know what is good and what is bad for the most part....

as long as you're not driving around blasting test tones all day, know how to properly set a gain, and know what mechanical noise sounds like, running more than RMS wattage shouldn't be a problem.
