Are Dual amps worth buying?

I have 1 10" Memphis 15-PR104D and I want a small cheap amp that i can get at a local store. I was hoping to get something about the size of a PS2 like the Memphis 500D that my little brother fried.

memphis / dual ?  no comparison.  memphis 500d is 500rms@2ohm. a dual 500 is probably 50rms@4ohm. have the bad amp serviced if you can.

Don't buy Dual if you can avoid it.  Get a mono amp.

mono is the way to go if you have one sub, it can put out max amount of power in a single channel....
just be aware, you gotta watch you dont over power that sub since it can only do 200w rms,
use a bit bigger wire too....

Ok i have narrowed it down to 2 amps for my 10" Memphis PR dual voice coil, but which one?

Both are mono sub amps and class D

1. Alpine V-power MRP-M450

2. Memphis 300D

OK I bought the Alpine amp but i am having a problem locating the stock amp for the interior speaker's. I have been told that it is in the trunk by the rear speaker's but it is not. This is not the bose system so what do i do?

All i need to do is hook up a line out converter for my sub signal. Will there be a problem if i just splice into the wire at the rear speaker's?

Assuming there's no factory sub, this should work fine. If there is a factory sub (I don't believe there is), use those wires. The factory amp may be in one of the rear quarter panels (I think passenger side).

Look underneath the vehicle where the sub box goes and check for any obstructions. If there are none, drill a few holes through the bottom of the box and floor (remove the sub for access), and bolt the box down. Use some fairly large washers when dealing with fiberglass.
