An amp that runs 2ohm stable and pushes 2 channels at 300w? That'll be out of your budget, on it's own

4ohms

If you're going to run in parrallel then yeah a 4ohm amp.

I'd go with the GTO-1014 or 12 variety meself.

[megamini_jb]

Main thing is I kinda understand most of it now....

till I go put my music on and blow the bloody sub!

[conlad]

Good man!!

Jus tget something cheap and cheerful to annoy your neighbors and if it doesnt annoy them then youv'e bought wrong ;)

[Skortchio]

You'll be fine, dude. Hard pushed to blow one of them :)

Cheers for the help dudes

[conlad]

No problemo. That'll bounce n boom like no tomorrow ;)

I'm sticking with just the single sub, just out of interest though, if I was to add a second sub like the one Im getting, how would that work? I'm guessing a mono amp would be needed (the amp I'm getting is that isn't it? or it can be bridged) and then would you add the 2 subs RMS @ 4ohms together and make sure the amp can run the 2 subs RMS added together @ 4ohms or is that when the impedance changes and becomes confusing.

Because you already have a monoblock then yeah you'd need a seperate amp. So in essence its a new configuration.

I.e. its like buying what you have twice

EDIT: if you had a dual amp (two channels) then it is possible to run two subs off it, or a 4 channel amp could run two by bridging 4 channels into 2

I see.

eer nope.

A mono block can run as many speakers as you want, as long as the impedance does not go lower than the rated amp capabilities.

The JX 500\1 can run down to 2ohm and produces a health 500 watts rms at that, so if you wire like below you are all good.:




I've seen old skool SPL system (20 years ago) with 6 subs on one RF amp... rate at 50 watts rms at 4ohm... running 0.125 ohms!! producing HUGE power.

[freshairmini]

to be honest two subs in a mini isn't really needed, unless you want huge volume, which again isn't needed as volume isn't a problem in such a small car.

Keep it simple with what you listed above (jl sub,sealed box and amp) and it'll sound good.

Sorry, I thought he meant he wanted another amp and then how to set that up in sync with this one... read it back now and I have mis read it lol Cheers ruckus
