go to jaycar man, good value for money...ive got the same sub and am gunna run it off my 4x100 haycar amp when my headunit arrives...will sound good

oh, bridged it does 380wrms (sub is only 300wrms)

i think the jaycar 2x150 would be a good choice, bridged it gives 500wrms.

I am using this amp with a sub that has similar power requirements, and was going to use it if i got a w3.

I think the first thing to check is if it is dual 2 or dual 4 ohm voice coils coz a dual four will only run at two or eight ohms thus a monobloc and a dual two will only run at 1 or 4 so probably look at a two channel and bridge it.

Just out of curiosity how much are you guys paying for the suitable jaycar amps just so i know what sort of budget you are shopping with.

W3s are hot man especially in the ported box but don't feel bad about giving it 400-500 wrms they love it as long as its clean power trust me.

Run mine in the shop (JB HiFi) in qld off a 500/1 and it is tight as. If you really want to hear it sing try a jl e1400D (if its a dual 4) and you'll never go back. If its a dual two ohm (less likely) go to JB and check the prices on coustic 600S two channels for comparison to jaycar stuff they are good for 350wrms bridged and sound great on subs especially for under $300.

jaycar amp is 249 normally, if you buy a few of them u can get them for as low as 199(look on website) and bridged it will only run 4ohm.

ive found most w3 ive seen are dual 2ohm...like mine is...

jaycar amps dont like to be run at 2ohms bridged...which is why i needed that dual 2 ohm sub...

mate go for an audibahn 8000T, ive got that and 2x JL 12" w3's and they quick hard, its an expensive amp but its worth it....

its a 1x1600 watts ach power, which is 1x 400watts rms

[jlaudio_33]

just to clear it up a dual 2 ohm sub will present a 4 ohm load if you run the two coils in series or 1 ohm if you run the two coils in parallel.

Same principle as wiring two single voice coil subs you can only double or half the impedance with each addition so two four ohm subs wired together will run at 2 or 8.

So the jaycar two channels are okay if the sub has two ohm coils, the audiobahn A8000T will give give 400rms at 4 ohm or 800 rms at two ohm. Mass_iv has also got dual 2 ohm subs as both subs would be wired in series to four ohms and the two subs would be wired in parallel to the amp to bring it back to two.

nice sub same one in my old skool capri makes some big sound even though it has a petrol tank behind the rear seat. i use a kicker mono block to run mine.

(note its a 71 capri not a convertable capri)

go to jaycar and get their new line of monoblocks, set you around ~$800

should be able to crunk out 800 watts RMS @ 2 Ohms, if your sub is dual 4 ohm

thats overkill for that sub, but in the future if you get a sub with higher power requirements it would be useful.
