Well you will need an amp that puts out about 300wrms @ 2 Ohm. You aren't going to get an award winning amp for that much money....

Where did you buy the subs from?

 

[gootynz]

Ohh ok, do you have any suggestions, I am also going to be using hertz HSK 165's for the front and FAKE hertz HSK 165 for the rear cause sofar they are free(dont ask lol), got the subs from Fhrx Studios Pty Ltd - Audio / Visual Specialists 450$ I allready have amps for the door speakers etc, Am i better with a single chan or double chan amp for the 2 subs ?,

Wow thats pretty pricey for two 8 inch subs. Never heard of the brand either

 

[gootynz]

They are suposed to very good quality, Much the same as DLS I was told,

So they are the dual 2ohm model?

Wire each sub in series (=4ohm), wire the subs in parallel (=2ohm) and run them off an Option Audio OAK600 (600wrms @ 2ohm). Should be able to get one for less than $200. They are a decent amp for the $, and compact/efficient being class-D.

Other options would be:
-Bridge a 4channel into 2x150W+ @ 4ohm (most 4x50w or better would be capable of this)
-Get a 2channel that does 150W+ per channel @ 4ohm - Jaycar/Response make a 2x150w in your budget.

Wow thats pretty pricey for two 8 inch subs. Never heard of the brand either

Pretty well known and quality brand amongst car audio enthusiasts...

Yes these are dual voice coils and 2ohm.
2ohm parellel with OAK600 be better idea than 4ohm option ? what would you do ?

 

[HEKYEH]

You won't find an amp for $200 that will give you enough power at 4ohm.

Also, rear door speakers are a waste of time. Unless u sit in the back seat when u drive??

Would this amp do everything run the subs and the fronts and maybe the rear or better to just user for front and subs ??? or not at all,
5/4/3/2 Modes I guess if I am to use this I would use either 2 or 3 channels ???

Use the sub channel, bridged into 2ohms so you get 300wrms. More power would be nice...but it is what it is.

Then bridge the front and rear speaker channels to give 200wrms @ 4ohm. Run the rear door speakers off the headunit. My preference would be to throw out the rear door speakers because they are useless.

But what would I know about Sound Quality.... The gear in my last car was worth around $15-20k And I didn't have any rear door speakers.....
