I ended up buying a 12" 1300w Sony Explod including the box for 50$. It's a 380RMS sub, and i'm using my 4chan amp. I've bridged ch1 and ch2 for a total of 280RMS so thats good enough for me.

Only thing I was gunna do was run ch3 for a left 6x9 and ch4 for the right one and set it on a HFP. Only prob is my headunit doesn't have another 2 RCA slots to run ch3 and 4

The amp should only have one set of rca plugs for input so you only need the one line coming from the head unit. So ch3 & 4 recieve the same signal as 1 & 2. Plug the speakers in, they should work.

I thought that would be the case but i couldnt get any sound out of the 6x9s and I tried different settings and nothing. It worked when i switch the RCA plugs into the other two amp inputs.
I'll have another play in the morning.

Figured it out after giving a mate a call it and was pretty obvious. Need a headunit with the second set of RCA out.

Oh, and I think my amp might be really dodge, because my subs already gone funny.

yer i think ur amp might be dodgy as i had no troubles when i had my 4 channel amp running them off 1 rca line

you can buy RCA splitters.. not that expensive, you get them from autobarn, super dear, REPCO etc

have used them heaps of times in systems that i have had. haven't had any problems with them

[Bucket]

When I turn my gain up or increase the LFP DB boost from 0->6 or 0->12, my sub just pops in and out and my whole system pumps this low "woomp" sound. I think my amps fucked.

it could also be the quality of ur rca leads and wiring

check those aswell as ur amp

[Bucket]

I went over my wiring a few times and it's all very strong.

I tried plugging my 6x9s into it and the same thing happens to them when I turn up the gain. Ah well, stupid cheap powervox

[BUZOOKA]

my powervoxs work fine for me

pumps my subs nicely

[royce]

motorboating its called, your wirings shit

gain is for level setting, its not a volume control!!!!

[BUZOOKA]

if u turn ur gain up to far u will blow ur amp and possibly ur subs
