If powering two separate sub enclosures, would I still use a mono amp? or would I need at least 2 channels?

also if the sub specs are

recommended power: 50-450 watts RMS (900 watts peak power)

and there would be 2 subs, one in each enclosure

would i only need a 450 watt amp, or a 900 watt because there are 2 separate subs?

 

wrong forum....

but you can still use a mono amp - it's all in the wiring

 

thanks for the reply, yeah i posted in car audio but not really anyone there right now..

do you know how many watts the amp would need to be?

one sub needs up to 450 rms, 900 peak watts

but i plan on getting two, each in it's own enclosure, so would i need an amp that goes up to 450 rms x 2? = 900 watts?

or could i get one between 450 and 900?

 

: Should I use a mono amplifier or a multichannel amplifier to power my subs?

A: Because mono amps tend to be Class D amplifiers, they are a good choice for powering subwoofers — Class D amplifiers have a high power-to-heat ratio and excellent efficiency, which are exactly what you want when dealing with power-hungry low frequency signals.

Most mono amplifiers are designed to run at 2 ohms; some are even 1-ohm stable. Multichannel amplifiers, on the other hand, are typically designed to work with a 4-ohm load. This is an important difference when using your amp to power multiple subwoofers, because you won't be able to bridge your multichannel, 4-ohm stable amp to power multiple subs that present less than a 4-ohm load. Instead, use a mono amplifier to power a 2-ohm load — two 4-ohm subwoofers, or 2, 2-ohm dual voice coil subwoofers, for example. You'll be able to push your subwoofers with the mono amp's maximum power, without running at a dangerous impedance.









so i guess i just need a mono since the subs are 2-ohm dual voice coil.

now i just need to figure out if i need the subs rms x 2 or just the rms x1..

 

power is still "shared" so a nice 1000w mono amp should set you straight

 

yeah it makes sense, lol, thanks a lot

 

ECLIPSE by Fujitsu Ten

damn that thing is sick!

i want a 450rms sub with 2 ohms, and it has a dedicated sub rms of 450 when using a 2 ohms sub!

and it still puts out 75 rms to all 4 speakers! sexy!

(and those numbers are typically underated, which you find out when you open the box)



eh, kinda silly though if my HU already does

Built-in Speaker PowerMOSFET 50W x 4



Continuous Power Output
22W x 4



I think i'm better off just getting a mono amp, yeah? or just get this Eclipse one for the 53+ watts more that it has as speaker continuous power output?

damnit, my current aftermarket speakers are 4 ohms.. so that would really lower the RMS on the Eclipse amp unless there is a way to wire them for 2 ohms

 

ok so basically the question is now:

can you wire four 4 ohms speakers to an amp so that they act as 2 ohms?

What is better 4 ohms or 2 ohms

so i guess that means yes.






Speaker / Amplifier Wiring FAQ - Tutorial hmmmmmm.. now i can't find any specs that say if my kicker speakers are DVC or not.........

 

DVC is dual voice coil. your subs will have 4 input posts. If your talking about door speakers i dont know of any that are DVC.
