I can buy a 400w clarion mono block for pretty cheap, will that power the sub? I should i go higher? Remembering the sub is a real **** clarion.

You'll be able to power that ****ty Clarion sub with like 150rms... Just check up what the specs are for that Clarion mono are... but you should be ok

Okay thanks, and for the time being ill just run the 6x9s and the 4"s in the dash off the head unit and save up for a 4 channel amp to power them.

You could buy a 4 channel amp. Run the front splits of the deck. Run the 6x9's off the amp and use the sub on the amp(parallel). 4 channel amp Channel 1 & 2 = pair of 6x9's Channel 3 & 4 = one subwoofer(parallel) You can do this as long as your amp has a low pass filter. You should have a switch on your amp where you can choose between high pass/range, mid pass/range & low pass/range.

Okay well whats the cheapest amp i cauld do that with? I dont want a really ****ty amp. I havent got the 6x9s yet but when i do i will buy some half decent ones that will probably be the same power as the sub. Cheers

What type of deck are you using/running?

Pioneer deh-1050e

This would be a good buy. I was just looking at JB HiFI stores and their's none located in Bairsdale. So your next best bet is E-bay, at least their cheap. Plus with this amp being the same model allows for the correct frequency output from your deck. http://cgi.ebay.com.au/PIONEER-GM-64...item2c54bd5858 (http://cgi.ebay.com.au/PIONEER-GM-6400F-4-CHANNEL-AMPLIFIER-600W-CAR-AUDIO-AMP-/190400256088?cmd=ViewItem&pt=AU_Car_Parts_Accessories&hash=item2c54bd5858)

Okay, well soon when i have more cash, will be a bit later im going to buy a new head unit, one with usb and stuff, will that matter? Thanks heaps! ---------- Post added 28-05-10 at 19:06 ---------- Okay well i have been talking to my friend, he can get stuff at store price at jb, its like a big store in nunawading, but he cannot order anything in only stuff at the store, so can you gives me a list of amps that they should have? I will also grab some 4" speakers while im at it.
