G'day guys,
just bought 2 subs (300rms) each, a clarion 4ch amp (only 400watt I think) would it have enough power to make these subs really pump? I have no extended knowledge about sound systems, but was told by many that it should be fine to run them both? Any help would be great, thanks. |

The amp can power the subs, but the subs won't see the full potential...which can be a good thing because you won't be able to blow them...better than over powering the subs till they blow.
Not sure what you mean by "really pump", but they will suffice in playing loud bass (depending on set up/tune etc.) Make sure you don't run the amp too hard to the point it clips the signal which in turn could cause damage to the subs.

I just want it to be quite loud from inside the cabin.
I got him to play a 250rms clarion in the sound room, and it was shaking the whole room , not sure what amp he was using to power it. By really pump, I mean the people in the backseat feeling the hair on the back of their neck stand up. |

So overpowering subs is bad.
To get the most performance out of 2 300rms subs, what kind of amp would you have to be running, keeping in mind it's 600rms all up. |

personally i would try to run them on around 250W rms each this way u can crank up the volume and be safe for extended periods of time
they will run pretty well on 200W RMS but not terrifically if u wanted to hit there max potential and still be safe ull prob need about 280W RMS each never go over somethings max RMS eg: pumping 400W RMS into each of those sub if u turn the volume up ull prob have confetti raining

Ok so they're single 4 ohm voice coils, running 300 rms,
and amp is Power, @ 4-Ohm, 60w x 4 Power @ 2-Ohm, 90w x 4 Bridged Power @ 4-Ohm, 100w x 2 so should be running 240watt? I'm guessing that's how it works, no idea about this kind of stuff. |

amp power is very easy to work out if your given all the info
so for eg: Power, @ 4-Ohm, 60w x 4 Power @ 2-Ohm, 90w x 4 so bridged power should be 4-Ohm 180W X2 to get ur bridged just get the channels ur bridging together and add there power together from the 2ohm output and u will have ur 4ohm output in bridged how does this work ? its simple the amp only applies 2ohm to each channel that are bridged together so the ohms build on each other and so does the power

So that would be 360watt, would it overpower the sub? 900w/300rms?

it would depend if the amp is capable of bridging all channels to one 360W RMS is in the warranty void area not many amps can bridge all channels into one i would recommend a monoblock amp
the amp u have inst capable of running your setup u have its not suited to it i would recommend 2 of these Pioneer GM-D7400M for a safe fun but for maximum 2 of these Pioneer GM-D8400M use your 4 channel amp u have to run your speakers 60W each channel is some pretty good speakers there but that does mean getting new speakers all round to suit 60W RMS each speaker i also hope u have taken into account the cost of wiring as wiring in 2X300W amps would be costly depends were u get it from but i recommend aeropro wiring its a good budget setup i would recommend running 1 wire from your battery to your boot and then spliting it up to run all your amps i would recommend using 2GA wire for the big wire that run to the boot then in series (all from the tip of the 2GA) run prob about 8-6GA wire from your 2GA to your amps

Hi well the store rep told me the amp should be fine, he's a Rockford rep. Can't really change my mine now, it's all paid for, I'll see how it sounds, may be able to get a refund and add a little more for a better one.
As for wiring, I got a wiring kit, the rep also told me is enough, we will just have to see how it goes. |

one thing ive learned is never trust salesmen they lie and s**t to get you to buy stuff and they will always point u towards what makes them the most money

Yeah true,
but would it be bad for the 2 subs? I just want it to be heard from quite a distance. Hopefully the amp can power it enough for that. |

it will power them just at half there potential

So will it be pushing, (60*4) 240w?
So 240wrms? Better than overpowering the sub isn't it? Your feedback has been very helpful, thanks. |
