what kind of amp do i need?
I have two Kenwood 10" KFC-WF253 subs already installed in the box. What kind of Amp do i need? Here are the specs:
500W peak
4 ohm
How much Watt amp and how many ohms, stuff like that, cus i dunno about amps.

You have to find out 3 things.
-What is the impedance of these woofers? Are they 4ohm...2ohm?
-Are these woofers dual voice coil or single?
-How are they currently wired together in the box?
All that will determine what kind of amp you will need. If I remember correctly, these are single voicecoil 4ohm subs. If so, chances are they are wired in parallel. You will need an amp that will put out enough wattage at 2ohms. Another thing is you will need to find out what the RMS wattage rating of the sub is...peak power doesnt tell us too much.

Yeah, sorry, i cant find any information about its RMS. and about the wiring? theres two subs, each has its own wiring out the opposite sides if that tells you anything:
--[O O]--
If its dual voice coil or single? no clue =/
Ive tried searching for the specs of this but all i find is:
250mm subwoofer, 500W, Free air design, Tornado shape rigid diaphragm

this is what you need to look at
see if there are either 1 or 2 positive and negative terminals on the sub (should have one of each on each side or just one set on one side). if there are 2 sets then you have what is called a dual voice coil sub, this sub either comes in a dual 4 or a dual 2 design. if you only have one positive and negative terminal you have what is called a single voice coil sub. depending on how you have them wired from there depends on the impedance.
from there we can answer your question.

If an amp has 2 channels, it has TWO sets of positive and negative inputs that can be controlled independantly.
