Need some advise on a cactus 5kw.........

shaker

Now according to the specs this is a 1 ohm stable amp ......... but the person i bought it from and a few other people told me that the amp could be used for daily playing @ 0.5 ohm ........... i don,t want to damage my amp so i need some advise from the experts......... can i play 2 d2 subs bridged on this amp...........

I wont advise you running that amp for 1 ohm daily playing,maybe just for spl burps,unless you have a shitload of batteries I would not advise you to do that

You should look into gettin a powerful 2ohm mono instead,maybe from Stetsom,Banda,Crossfire.. They would run your subs more efficiently.

Or maybe changing the coil configs of your subs, to dual 4 ohm each to get a final impedance of 1 ohm

fuzz , sorry i made a mistake , my car is a competition vehicle and the purpose of the amp is 4 crowd pleaser / gallery ........ what i need to know is , can the amp play a pair of dual 2 ohm subs @ half ohm without damaging the amp.........

More importantly, What is your electrical system.

oh, i now see you mentioned Cactus 5kw.. which is basically the same as the Atomic 5000.1.. which is what i saw tested..

here are 2 Atomic 5000.1's strapped at 0.5ohms (or 0.25ohms per amp!)

his electrical is a 220A alt and 5 batteries...

my electrical system consists of 1 2000 powermaster in the engine bay , 3 3800 kinetics in the back and a 200 amp power master alternator.........

i still want to know what is the pair of subs please
i am familiar with his electrical system.

why?
lets say the amp runs at 4500rms at 1 ohm comfortable,
and he connects 2 5000watt subs to it at 1/2 ohm,
then he would have to max out his cactus at 1/2 ohm and play bass for almost a minute(because its for gallery)
and he would max it out because that power wont be enough to drive the 2 subs properly.

Now if he was to connect 2 p3 12s to it to come down to 1/2 ohm, he could go play all day long, that wont hurt the amp, because all he needs is about 1500watts.

but not maxed out at 1/2 ohm, i dont think any amp would hold up that is rated for 1 ohm stable.

-unless the dealers have personally tried this out and found it to hold up-

i bridged 2 channels of a rockford 800@4 at 1 ohm already and had it played one a my dds, i was flabbergasted by the power out, but after 20 seconds it was burning hot.
Had i continue it would have blown.

Its all about what u are going to do with at that ohm load that will will decide if it will work.

you for real man

could you explain whats wrong with what i said?

(...Rovin...) · Posted: Wed Nov 11, 2009 5:56 pm Post subject:

company rec 250Ax2 fuse for this amp

though it can work like fuzz & 3stage said its going to suck alot of current + ur other mids\highs amps will have to share current from those 3 batts as well

if was for SPL which only need a 3 second burp then its no problem

its risky for music playing but CP is 'only' 45seconds so u can try it & see how d voltage holds up

i have a 200A alt & was running 2 pb 3000d strapped (on a @ 1ohm load) which also uses 250A x 2 fuses , i have less AH than u (probably less mids\highs amps than ur set) & in my case d current held up good but it might be a different case for u

u cud always install d4 kits on ur 2 subs instead ... Neutral

there is a reason subs come in different coil configs likewise amps

match them up properly that is all
if someone "tells" you if can play to this and that impedance, when your amp bun down i hope they give you back your money

this is so simple why do ppl make a deal out of this
the only exception is for extreme spl reasons and I HIGHLY doubt this is the reason to be doing this

this guy reminds me of southside last year Surprised

The subs are a pair of DD 9510,s ......
