What do you think about this amp???

[dom08]

Ok so i have done some research and was looking at a GLI pro PVX-9000 amp;
here are the specs.
Power output:
PCX9000:2X500WR MS @ 4OHMS(stereo mode)
1x900WR MS @ 4OHMS(Bridged mode)
Total harmonic distortion: less than 0.1%
input sensitivity & impedance: 1.0v (0dB) RMS, 10K Ohms
Signal to noise ratio: more than 100dB
Frequency response: +/-0.5dB, 20hZ 20 KhZ
19" Rack Mountable
10,000 Watts Maximum Power
2000 Watts Per Channel RMS
Channel Volume Controls
Clip/Protect Indicator
Turbo Cooling System
Bridgeable
THD: Less Than 0.1%
Input Sensitivity & Impedence: 1.0V (0dB) RMS, 10K ohms
Signal to Noise Ratio: More Than 100dB
Frequency Response: +/- 0.5dB, 20Hz, 20kHz
Power Supply: 115V-60Hz/ 230V-50Hz (Switchable)
19"w x 5 1/4"h x 16 3/4"d
Shipping Weight: 40 Lbs
Made in China


These will be used to power my cerwin vega vs150; One amp per speaker.
What is the difference between 4ohms and 8ohms??; my speakers are 4ohms
what is the proper way to bridge one amp for one speaker?
Also, would you recommend to have a amp for a center channel?

what do you think?

thanks alot
Dom

It might work and it might put out what it shows. Then again, it could be a very brief experience for you.

Speaker impedance is the measure of several things and shows the resistance to Alternating Current flow. Current is a function of voltage and resistance, so if the Power remains constant and the resistance drops with the voltage staying steady, the current will increase. If the amp can't handle the current demands, it gets hot and in extreme cases, it dies. Sometimes, it just blows a fuse.

How this amp needs to be wired for bridge mode will be in the instructions.

Can your house wiring handle that?

Keep in mind that bridged amps "see" a speakers impedance as half of it's rated value.

why wouldnt house wiring be fine?

Because at 120V, a 15A circuit works out to 1800 Watts (Ohm's Law states that P(Power)= I(Current) x E(Voltage)). An amp can't put out more power than what's available from the circuit and that's one reason it shows that it can be wired for 220/230VAC. A 15A circuit on 220 works out to 3300 Watts. Two of those amps bridged into 4 Ohms, assuming the specs are accurate and that the amp is 60% efficient (nothing is 100% efficient), will draw 3000 Watts, which will pop the breaker on a 20A circuit at 120V.

Because 2000W RMS is more than a 15A 120V power line can provide. The most a 15A line will provide is 1800W and that is into the device. Efficiency isn't 100% so you aren't going to get 1800W from an amp that is pulling 1800W from the wall.
