Yes, set to mono. Are those 15 " subs ?? If that is, I really don't think you have enough power from this amp to run those subs ?

no they are 12's, so do i leave the amp set to stereo, but only use one side?

They got 250 watts max cuz that's the total peak power that the amp can put out during a musical peak.  It's not really a meaningful number but many manufacturer's label their amps that way cuz a lot of people don't know the difference and just think the bigger the number the better the amp.

The 120 watts RMS bridged is what the amp puts out when you combine the left and the right channel into one output channel, usually to drive a subwoofer (or two in your case).

For this amp, you will actually not set the switch to mono.  That is only if you have one input signal (just white, as opposed to white and red).  Leave the switch on stereo.  Set the "filter" switch to "LPF".

After you've wired the subs together using Jeff's diagram, you'll end up with one positive and one negative speaker wire to connect to the amp.  On this amp you use the positive from the left channel and the negative from the right channel when you are bridging it (it says "Bridged" and has arrows linking these two outputs).

What is the exact model number of your subs?

Check your power connections. does the amp turn on when subs aren't hooked up? make sure wires are not shorting out any where. The amp should tell you where + - go for
mono. make sure you follow that.

So the amp doesn't work but the rest of the system continues to function?  and what model subs are they?

BTW it's a 15 amp fuse, not a 1.5

If you're gonna be using the high-level inputs to send the signal to the amp, you wanna make sure that RCAs are not also connected.  Never use both sources at the same time.  Maybe that's what your problem is?

Also, I'm almost positive that you leave the switch on "stereo" as it appears to be an input select switch.  It says MONO (L ch) and I took this to mean the input.  It's gonna automatically sum the left and right when you bridge the amp anyways.  Others may want to verify this, just check out this pic.posted_image

Even if that part is wrong, which I highly doubt, that still shouldn't be causing it to blow a fuse.  You can always try switching over to mono just for the hell of it.
