Does this mean you can put (4) 4 Ohm speakers on this unit (parallel to 2 ohms per channel), and get 12.5 watts per speaker? Is that loud enough?

Power and loudness are not necessarily tied. There are a ton more things involved...in the sense that you need horsepower to go fast, but going fast doesn't mean you make high hp...if that analogy makes sense to ya.

That being said, that system is weak, and rediculous.


Go to an audio retailer and but a Marine Grade 3.5mini to RCA cable. This will hook your audio-out headphone jack from any small-electronic, and convert it to Stereo RCA, which 99% of amps use for input. You can then wire speakers off a 4 channel amp just like any other audio system.

4 Channel amps are plentiful, and can be had for like $40 used if you really wanna keep it cheap. Even a good 4 channel will only run $150-250. On top of that, the cable itself will cost around $12-20.

If you want an added level of control, you can put an inline volume control in the line so the ipod doesn't have to be the volume control.

Doesn't get any more simple, total cost is as little as $20 if you already have an amp.
