Fixing the OEM Subwoofer 'POP'.

Fixing the OEM Subwoofer 'POP'.
OK. What is the correct way to do this? I have searched through these forums and this is what I have found:
These are just some of the solutions I found. Can anyone tell me which one of these (or any others) is the 'best' solution for the subwoofer pop problem?
Or, maybe this unit for $11.99 is the way to go?

Here is the information I got from crutchfield when I asked about my factory sub system.
"The factory stereo only sends 5V to the sub amp. When an aftermarket stereo is installed, there may be a turn on/off pop from the subwoofer. To avoid this, a 12V to 5V regulator can be installed on the remote lead. The Radio Shack part is 276-1770. (This regulator has three terminals: the first is the input, the second is the ground and the third is the output. The regulator produces a large amount of heat for its size and should be bolted or screwed to a clean metal surface that will act as a heat sink)."

Thanks for the replies.
The voltage regulator seemed like the best solution, so I went ahead and ordered the pre-wired version from SMinnTech. It should make the install a little easier since the wires are already soldered unto the regulator leads. They also add capacitors to the input/output leads to prevent oscillation on the output side. Just a little extra protection for the sub amp.

Worked for me too
I installed this fix.
Head unit is a Pioneer AVIC F900BT with the stock Ford subwoofer. It would "pop" when the key was turned to the on position.
The voltage regulator was installed (Radishack part number 276-1770 - Model 7805 - $1.67) as shown. No more pop. Works perfectly.

I hate to delve back into a 2-year-old topic, but this is the issue I'm faced with. I know I need a voltage regulator, but I'm a little confused as to what amperage is needed for the subwoofer 'pop' fix.
A lot of the '7805' voltage regulators that I come across (we don't have Radio Shack in Canada anymore) are 1.5A, while I see some that are 1.0A. Does the amperage even matter? I know it has to be +5V, but I need to know if it matters what amp rating I buy.
Thanks, guys!
