you need to add extra mosfets,
talk to PuRpS, or do a search on 2X150 mods..

i'm not sure but i dont think the jaycar 2x150 can run a 2 ohm. Any how, you connect 2 vc to one channel. Running the positive off a single channel over the two positive conacts of the vc's and the negative of the single channel over the two negative contacts of the vc's.
I'd suggest you wait until someone can clarify whether the 2x150 jaycar amp can handle it though.

well what amp 500 will run really powerful at 2 ohm and how do i do it?

(im really curious)

if you have the 2x150 .. mod it appropriately and it'll happily run 2ohm for daily driving.

purps had theirs running HARD for a few hours before it shat itself.

but if u do want a new amp which is 2 ohm stable .. then look into the kicker ZRs .. they are preceded so if u can find out you'll get em for a good price. methinks they are best value for money.

and in order to get the amp the 'see' the 2ohm load bridged .. just do what 4subhatch said.

basically .. just wire 2 4ohm VCs (whether it be 2 4ohm SVC subs or a DVC sub with 4ohm VCs) in parrallel.

nah man .. 2ohm bridged i think he is what he talking about

Been running mine at 2 ohm mono for a couple of weeks now no worries, although its got some fans on it http://www.caraudioaustralia.com/ubb/smiles/smile.gif gains are only on half... can't wait to open it up for a meter http://www.caraudioaustralia.com/ubb/smiles/biggrin.gif

wldwagon: do you know what you plan to run with the amp?

you could also consider the new alpine class D MRD-M300 rated at 1x300WRMS into 2ohm, RRP$599. note that this will be at least a genuine 300WRMS when driving subs; most wimpy amps drop off their power outputs powering subs with subbass frequencies.

however the old ZR kickers are indeed great too.

good luck http://www.caraudioaustralia.com/ubb/smiles/smile.gif

yeah it would be interesting to see if someone actually benchmarked a jaycar 2x150 in 2ohm bridged and see what it actually puts out at subbass levels.

I've got an oscilliscope here... how do I use it? http://www.caraudioaustralia.com/ubb/smiles/rofl.gif seriously my dad uses it for work, its got 100s of knobs I have no idea what do http://www.caraudioaustralia.com/ubb/smiles/smile.gif

if you don't know how to use it, i certainly wouldn't be mucking around with one. not only are they sensitive, expensive pieces of equipment, i believe they can be very dangerous too (= electricution).

but sure, get your dad to help out. you can use it to visualise power outputs by using it as a voltmeter. you'll get a very scrappy signal unless you use nice test tones (simple sine waves). from the screen you can measure off voltage, and i figure if you can also meaure current, you can calcultate watts. at least i figure it's that easy. haven't used one since high school. http://www.caraudioaustralia.com/ubb/smiles/laugh.gif
