I just found an Alphasonik A-501 E auto stereo hifi power amplifier.

It states the minimum specs but i have two 10"BOSS subs in a ported enclosure and i want to know if they'll sound good with this amp.

I would also love to know the max power i can pump out of this thing.

minimum continuous average power:

stereo mode: 50w per channel, both driven into 4 ohms

mono mode: 80w into 4 ohms, 100w into 8 ohms

frequency response  20-20,000Hz

<0.1% distortion @ rated power

signal to noise ratio: >85dB

equalization +6dB @ 60Hz

And my speakers are BOSS CH10 Chaos 10" subs

will the sound nice?

According to Ampguts, that is a one channel amplifier.  They say on the site that the amp is mislabeled as a 2 channel amp.  The numbers you posted which are the same numbers on the amps sticker is not accurate.  The 8 Ohm mono is the same as the 2 X 4 ohm rating   50left 50right = 100 into 8 mono.  The 4 ohm mono should be more than the 8 ohm mono rating.   AmpGuts shows it as a one channel amp.  1 X 50 into 4 ohms   and 1 X 80 into 2 ohms.

well in other words im asking if i hooked it up to TWO 10" subs (200w RMS ea. 400w peak) will it even work? I have them running off my stereo right now. but i just dont like the fact of trying to turn it up and possibly frying my whole deck. and i want a little more bass out of them....

It will do much better than your deck.  But we need to know more about the woofers.  Are the woofers single or dual voice coil?   What is the impedance of the coils?

1.5" high temp kapton voice coil. so im thinking one each and they have a 4 ohm impedance.

Option 1 (parallel) = 2 ohm load
Speakers wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono

ok i got all of that but with this amp, since it is a falsified 2 channel it has 2 speaker outputs.

on both of those wires the + have 32v 4a fuses.... remove them? replace them?

if u can please try to find a pic with the wire map on it...... i think ull get where im coming from...

If green and brown are both either negative or positive, and Blue and Grey are the other polarity, it is definitely a 1 channel amplifier.  I trust Ampguts a lot more than whatever country produced that amp.  If you zoom in on the following picture, you can see that those pairs of wires are connected to the same location on the board. http://ampguts.realmofexcursion.com/Alphasonik_A-501E/inside1.jpg   You can verify this if you have an ohm meter of any sort.  The 2 positive wires should show very near 0 ohms.  The 2 negative wires should show the same. 

You need to keep the fuses.  They will protect your speaker if the amp has a catastrophic failure with the output transistors.

ok the positives are the gray and brown on my particular unit. i also have fuses that will support slightly more power than the ones that are on here. should i switch em out?

Thank you very much. im no noob when it comes to this stuff but im no expert. appreciated greatly!!!
