Re: please look at this
The least u wud need is - 1 mono amp 600rms to power both subs.
Or 2 amps 300rms - mono.

Re: please look at this

Re: please look at this
right im gettin comfused on this channel thing....
If i have two subs then that is effective ly four wire that will be running to the ampifier. Two positives and two negatives. Four wires.
So does that not mean i need a four channel amp?

Re: please look at this
no no each channel has a possitive and neg output which the wire attaches to so a 4 channel amp would have 8 wires going in to it if using 4 speakers but when u bridge an amp its diffrent and as for a momo amp 1 channel u join the both posi wires together put them on the posi connection and do same with neg on the neg connnection so its 4 wires going in to a 1 channel amp

Re: please look at this
right, i sort of understand that so basically it doesnt matter what channel amp i get... but considering im not wiring my speakers up to the amp i might as well get a 2 channel or a mono block amp...
so which one would you choose?

i used to use an alpine mrd m500 which is 4 yr old now and sold to a mate is still pounding 2 subs so i like my alpine that was good in its day with 500 rms but really up to you and what you can afford dont do what i did paid 400 from halfords and at same time it was like 250 online!!
ps.i also blew 3 vp4 mono vibe amps before it but apparently it was a dodgy watch neva less i wouldnt get a vibe amp again

Right first of all lets get one thing out the way.
For a Road Car, 600wrms is more than enough. Cheapo Chavvy companies have runined Wattage, By plastering 120000000w on 6x9s etc etc. Put this into consideration, A stand Renault hed unit is probably sending no more than 10wrms to your door speakers, And upratedd one with a 4x50 internal amplifier is putting out around 25wrms.
600wrms is about the absolute limit you can send to the subs you have.
A channel is basically a positive + and a Negative terminal. When it comes to multi channel amp, You basically need a channel for each speaker. So if you want to run 2 sets of speakers (2 Left and 2 Right) thats four in total, so would need four channels.
A Monoblock amp (Class D, Sometimes called a "sub amp") is a one channel amp. You can run x amount of subs off it, But adding subs changes the final ohm load or impedence shown to the amp, so the figures it puts out are different.
An amp will be X amount of Ohms stable, Ie, The lowest impedence you can run on a 2 ohm stable amp is 2. You cant run 1 ohm on it,
Your Subs have voicecoils (which in simple terms are terminals) Some will have a Single Voice Coil (SVC) with 1 positive and 1 negative terminal. However, AS there are a huge range of amps out there, All with different specs, There are alot of Dual Voic Coil (DVC) subs out there, Which have 2 positives and 2 negatives. The advantage of a DVC sub is there are various ways to wire it to give you the choice of what ohms or impedence you wil lshow the amp.
Your subs, (1202D's I believe??) are Dual 2 ohm, a Pair of These can be wired to show various ohm loads, In this case, I'd wire them to show a 2 ohm load, In which case you need an amp that puts out around 600wrms @ 2 0hms.
The amp will have ONE channel, But both subs can be ran off this as its a monoblock.
have a read of this thread, Very similar situation to yours, And I've posted a few times in a bit more detail.
There is an amp recomended in there by myself (JBL one, Forget part number) that is ideal to your application

I owe it all to Forums, 3 years ago, My first post on an audio forum was asking what switch i press to change the impedence 
IF you are confused regarding wiring the subs, And what impedence will be show, Theres a few wizards on the net, I used to use em all the time, But ive done that many installs now, I sadly know them off by heart
