Sorry man
If you can check the Amps specs I would be grateful
It's a 4 channel Amp and I will be using bridging 2 channels to get 162WRMS @4Ohms
The other 2 will be used for a component set
Will it be enough?
Cheers

Is this thread more suitable in the Speakers section?

your underpowering the sub a bit but it will be fine it will work just fine as long as you remeber to run the sub in 4ohm config

if you have the dual 4ohm sub itll be about perfect, remember just dont clip the amp and youll be alright it wont even be noticeable if you had 60 watts difference if you have the single 4ohm sub.

You mean the Sup or the Amp? (the pdf is for the Amp)
Yep the Sub is both dual and single 4Ohm
And the Amp is bridgeable and can run 4/3/2 speakers on 4Ohms.

How does the dual 4Ohms Sub work? Does that mean a dual voice coil? Can it be connected to 2 amps, run as a 2Ohm or maybe 8Ohms???
Cheers

my sub is a dual 4 ohm i just has two voice coils i run it in two ohm off a mono amp. you can run them as 8 ohm or 2 ohm.

The only way to run a dual 4 ohm v.c. sub to 2 ohms or 8 ohms is the way you wire the v.c.'s together. Parallel configuration will give you 2 ohms and series gives you 8 ohms.

I would not recommend running 2 separate amps to a single sub. If the adjustments are off on the amp a little, it could potentially harm the sub. Just use one amp for that sub.
