Hello,
I just randomly bought Almani headunit which has USB, AUX & FM Radio but no CD. Well, I am satisfied from it. It has (40W x 4) mofset built-in amplifier. Lol. I am now running 4 Almani speakers on it. All are 4ohm impedance and 2 are 800watt peak output and 2 are 1000watt peak output. I know that there RMS would be wayyyyy lower than these peak outputs and these peak output's might not b true. Whatever, but I found a woofer in my store room. It's a lot old but I want to use it anyway in my Mehran. I went to Hall Road to the same shop and he is my friend. He is giving me a 4channel, 1500watts max amplifier, it is silver and veryyyyy long amp. And he is asking 7,500 for it and 1,000 for bass tube and I have my own wiring of woofer and of amp (wiring of woofer and amp, which I found with the woofer but unfortunately, couldn't find the amp). I am now confused that on the 1500watts max @ 4ohm, 4channel amp, will my 4 speakers and this woofer run MAZAYDAR? +Wiring jon si hai, voh series me krni hai k parallel me, wali bukwas voh, myra dost khuddi karay ga. Lol. :'D

Btw, the amp is silver in color and is damnnnnn long! :')
Also, it's model number is BA-510, I forgot the company name and yeah, under the company name there was written, "Engineered & Made In USA", there was something written on it, "1500watts into 4ohms", please do tell me if you know what this means! 
+The amp was looking really expensive and it was long and it was heavyy. I really looked HQ bah I was not sure so I came back to ask from the experts first. 
++Any help would be highly appreciated!
Thanks In Advance! :'D
