hi, i was wondering whether it is possible to wire two amps to one sub because i am buying a 1000rms sub and i was wondering if i could buy 2 500rms amps to power it?

[Don't Panic]

yes i believe its possible but im not entirely sure how you would wire it, possibly by bridging the two amps together, ask where you get the wiring cables from. You will need heavy duty wire!

if you could afford a TRUE 1000w rms sub - then a 1000w rms amp would be pennies in comparison :wink:

What one are you looking at?


and by the way, unless it was a dual voice coil sub, and you used an osilscope to set the gains to be EXACTLY the same - dont expect the amps/sub to live very long

this sub:

but a 1000 watt rms amp costs way more, i was thinking about bridging two of these to that one sub:

I'd personally leave that amp well alone - as they dont say the RMS output, only "peak" output


and I stand by my statement - dont join 2 amps together, it'll only end in tears

[mini_basser]

You can indeed wire 2 amps to one sub

What's your budget for the amp(s) though? IMO there's not much point shelling out on a decent sub like the X and then going for cheap ampage...i.e. Sony :fear:

Have you got the sub already?

[Brawlyrox]

Just dont do it!!! AS Chair said it will end in tears!

yep agreed with CC, 2 amps to one sub is possible but not a very clever solution, best to get a decent 2channel or preferably mono.

If you are spending that kind of cash on a sub don't you need to be spending a few hundred on an amp, then when you've done this you'll need to make sure the battery and charging system are up to the job.

to be honest unless you've got about £500 to spend on an amp i wouldn't even think about it, just buy a sub you can afford to amp properly.

here's a few that would do the trick

Genesis Profile Sub Ultra

JBL BPX1100.1

I wouldn't bridge 2 stereo amps i would just bridge cheap mono amps... surely the output of one amp could go into the input of the other? or is there limitations of what input you can have?

[chairchild]

input ignores current, and only looks at the voltage (max is around 7v)

If you try to chuck it in any louder, you'll either just get massive distortion, or you'll fry something



the only way it's remotely possible, is to link them in parrallel, and hope that the amps are working at exactly the same frequency rates, otherwise they'll be fighting each other, and shorting each other out

If they do that, you may as well just connect the amp power leads together and short it out that way - saves having to destroy 2 amps
