is my amp to much for my speakers ?
Here is my setup, My speakers are peavey sp4's, and my amp is a pyle pro pea4000. the specs on my amp is * 4000 Watts Max Peak Power Amplfier
* Two Channels Stereo Or Bridge (Mono) Output
* Independent Volume Control For Each Channel
* Balanced XLR And ΒΌ'' TRS Inputs
* High Speed Coolng Fan
* Lowest Noise -Smooth Operation
* Signal And Clip Led Indicators For Protection And Performance.




* Speakon-Binding Post Speaker Terminals
* Thermal And Overload Protection
* Power Output: 260W (RMS, Stereo, 8 OHM)
* Power Output: 400W (RMS, Stereo, 4OHM)
* Power Output: 800W (Bridged, 8 OHM)
* Power Output: 4000W (Max Peak)
* Distortion (Typical): <0.08%
* Input Sensitivity: 0.775V, 1V, 1.4V (Adjustable)
* Impedance: Unbalance :> 10K Ohm Balance :> 20K Ohm
* S/N: >103Db
* Frequency Response: 20Hz-20 KHz, +0/-0 Specification.5dB
* Raise Rate: >45V/Us
* Damping Factor: >220
* Cross Talk: <-78db @ 8 OHM
* Power Supply:115V-60Hz
* Dimensions: 3.5''H X 19''W X 15.9''D


and the specs on my Peavey sp4's are


* Quasi-three-way, full-range, bi-ampable sound reinforcement system
* RX(TM) 22 compression driver with ferrofluid cooling
* Two 15 inch BWX Black Widow(R) 4 inch voice coil woofers
* 4000 watts peak
* Patented Asymmetrical Quadratic Throat Waveguide(TM) technology
* Patented Radialinear Planar Phase Correction System
* Sound Guard(TM) III tweeter protection
* Frequency Response: 52 Hz to 17 kHz (+/- 3 dB)
* Sensitivity: 100 dB (1W/1m) anechoic
* Full-range inputs include a Neutrik(R) Speakon(R) 4 pin jack and two 1/4 inch phone jacks
* Bi-amp capability via internal wiring jumper
* Trapezoidal enclosure
* Hammertex durable covering material

The amp has two channels to adjust for impedance. I use two speaker cords with speakons. one goes to chan 1 and the other to chan 2. and i put the switch to "full range".
I keep blowing either a fuse to the crossover or the diaphram on my horn. Normaly its feedback from my mic that does this . How do i avoid this?

What mixer are you using?

You can't use just and amp like that with a microphone. You either need to add a cheapo mixer or get a mixer with amps built in.

PS: I'd say except for the amp being a Pyle of $*#^@%, that they mate up very well.

If your problems are caused by delivering excessive power to the speakers, you can achieve all the benefits of a lower powered amp by, uh, turning down a bit so your current amp sends less power
