what amp to power these subs?

[Matt M.]

I've got 2 of the rockford fostgate stage 3 4-ohm 500 watts rms subs and I was wonderin what amp would power them the best?I've heard mono amps are good for 2 if you use both subs on the same channel but I'm not 100% sure

If you use a mono (1 channel) amp, you will have to put both subs on the same channel :lol:

I'll start by giving you your options.

Your subs are dual 4ohm, 500w rms. A pretty good start....

If you go with a mono channel amp, you will wire the subs up in a 1, 4, or 16 ohm load. Obviously, you dont want a 16 ohm load, so 4 or 1 is the way to go here. Pretty much any amp will carry a 4 ohm load with no problems. If you go 1 ohm, make sure you get an amp that is 1 ohm stable (harder to find and more expensive).

Option 2, the way I would go for your subs, is a nice 2 channel amp that is 2 ohm stereo stable. Wire each sub to 2 ohms, on each channel. Efficient, easy to find and can be inexspensive.

I would look for an amp that is around 800-1000w rms and a decent brand. Every person will tell you a differnet brand to buy, but just use the internet to look up reviews and make an educated decision that you will be happy with.

and how would I wire up a 4ohm sub to a 2 ohm load or whatever.

Wire each sub like this and get a nice 2 channel amp.

And I had to edit my first post, its 1, 4 and 16 ohm in mono, not .5 ohm.

[Matt M.]

alright thanks.so can you point me to a amp that is good enough to give me anough watts to push the subs to their full potential?

[Matt M.]

I found a profile ap2000 amp.it puts out 320rms @ 4 ohms and 480rms @ 2 ohms.would that be a good amp?

[djgizmo]

Nope, profile / lightning audio and other brands are natorious for over selling their products. (their 320 watts is probably closer to actual 150 watts)

Rockford T1000.1bd

probably will do around 1500-1700 RMS @ 1ohm. Sounds like too much but its perfect really.
