I have this set up http://www.sonicelectronix.com/item_...ed+System.html

Im not shore what the watts are for the amp? In the Reviews for it, some people say its 400 watts. Iv google the model number and they dont sell just that amp, its only for that kit.

A friend gave me his xplod amp http://www.sonicelectronix.com/item_...+XM-554ZR.html I hook it up and it hink it sounds better with more thump. But im not shore what amp is better?

what do you guys think?

Also i was told to go for a high rms out put, and the xplod is 260 watts, and it says visonik is 500watts? So wouldint that make the amp more than 400 watts?

 

Sony is better than Visonik, but you need the amp that matches your subs. I'd keep the amp you have and pawn the sony amp. With the Sony amp you will be underpowering the subs and it won't sound as good as it would with a properly matched amp.
