Sony Amp and crossover

[tjl1388]

Since we're on an audio kick around here lately...these were in my new XJ and I don't need them..

Sony Xplod 1100 watt Amp, gently used. Not really into the loud stuff anymore...I guess I'm getting to old. Pictures by request.

Exactly like this one... http://www.amazon.com/Sony-Xplod-XM-SD22X-Amplifier-2-channel/dp/B0007OPHCU

but half the price.  $65

Coustic XM4 Crossover. It has a built-in line driver, stepping up voltage to 8V RMS. (whatever that means)
$50

$100 for both.

I know nothing about the new audio equipment, but want more sub and power in my boat. 

Has 2 amps now, a 12" sub, 6 speakers in the boat, and 4 tower speakers on the tower. 

1 amp powers the tower speakers, and 1 powers the sub and boat speakers.  Want to separate that.

Am going to add a bigger sub and more power.  Will this do it?

How much power does it take to shake those big low notes?

You will want to look at a sub that has a narrower frequency and in the range you want. I think you are wanting low frequency. The broader the frequency range, the less dedicated it is to a certain note. If you will notice the expensive ones don't have that broad spectrum, and the cheap ones are wide. Do't really worry too much about the watts.
