Default Amplifier Help

Right now I have 2 - 10" Infinity'*
( http://www.futureshop.ca/catalog/pro...est%5Fcookie=1 )
in a ported box running off of a Rockford Fosgate t5001.bd aplifier.


The subs are rated at 250 watts RMS each. The amp is rated at 500watts RMS @ 1ohm, but on the birthsheet I got with my amp it is actually 950watts RMS when it was benchtested.

Right now I have the gain close to all the way down on the amp.

My question.. is it bad to still be running these subs with this amp?
How should I set the amp (Gain and Hertz)?

Thanks!

Mick

Even if the amp is rated at 950rms which is probably at a 1ohm load. You dont have to wire the subs to present a 1 ohm load.



Or you can wire to 1 ohm and keep the gain way down. Either will work.

you need to set the freq to somewhere around 25-27 hertz. As that is the lowest the sub will play.

Thanks for the reply corvettecrazy.

Right now I have it wired right now to 1 ohm. I will just set the gain lower and run it like this. Its better for the subs to have the hertz set low?

I guess that depends if it is a low pass or high pass cross over. I should have thought of that first. If it is a low pass then you will want to set it to somewhere around 100 IMO. Others will say differently. Depends on your set up and if you have the 6x9'* installed.

give the subs a chance to break in and then set the gain by basicly turning the system up as loud as you will ever listen to it, and slowly adjust the gain until the subs begin to distort and then back the gain off that point a little bit and leave it there. (DO THIS IN A REMOTE WHERE NO ONE IS AROUND)
