RE: HK Citation 16 vs Ashly FTX 2001

Current can be described as a function of power and resistance in the following equation:

I² = P / R

This means that current squared is equal to power divided by resistance. Therefore, current would be equal to the square root of (power divided by resistance).

For the Ashly:

I² = 500 / 4 = 125

I = the square root of 125 = 11.18-Amperes

Alternately:

I² = 675 / 2 = 337.5 or 18.37-Amperes

For the Citation:

I² = 175 / 8 = 21.875

I = the square root of 21.875 = 4.677-Amperes

Alternately, if the power is based on 4-ohms, current would be 6.614-Amperes

It looks to me like your Ashly FTX 2001 produces more current than the Citation.

On the other hand, if you can borrow a Citation and connect it to your speakers, you can determine which amplifier produces better bass. That's probably the best way to evaluate the difference between the two amplifiers.

Good luck,
