Quick Question?

[cheese20323 13]

So I in the market in buying a 4 channel amp I need about 100 rms per channel going cheap on the amp crunch or MB quart. But my question was if i buy the amp i can use 2 channels for my front stage and can I leave the other 2 for a sub? And most amps are only bridgeable at 4 ohms so this means it is 20 ohms each channel? And my sub is a 4 ohm DVC so if i wire it 2 2ohms it going to be at 1 ohm? So what I'm saying is will I be able to run a front stage and a sub together?

Yes, you can bridge 2 channels to the sub at 4ohm and run 2 channels in stereo to your front. For instance the DSC4125 can run 125w x 2 in stereo and 500w x 1 to a sub.

you kinda lost me on that 20ohm part so i am sure there is more to your question that i didnt help with.

Edit:

I failed at reading your sub is dual 4 so no that will be a no go.

Yeah i just wanted a temp set up until i get the big amp but i guess i cant bridge the amp you did answer my question tho...

[Sir-Lancelot 216]

How cheap?

you could always get a 4ch and use it later on the highs.

[cheese20323 13]

That's what I'm going to do but i just want my subs going first then do the front stage. I still don't have speakers so I need speakers first then the amp. But I'm getting the alpine type r 6.5 components and maybe a crunch pzt 900.4 or hifonics HFI100.4 so yeah just had the quick question on the sub part but thanks for your help will need alot of help in the future if you have any other amps for under 120 and 75-120 rms show them....LOL

Mash Here

4 x 80/4 x 160 or 320 x 2 - In your budget!

You can't wire a 4 ohm DVC to a bridged pair of amp channels unless the amp is stable at 2 ohms bridged, which 99% of amps are not. And no it would not be 1 ohm, it would be 2 ohms on a pair of bridged channels. You even said it yourself, "my sub is a 4 ohm DVC so if I wire it to 2 ohms," stop there. 2 ohms. You can either wire one coil to each channel or series the coils and bridge the amp, in those cases it will either be 4 ohms stereo or 8 ohms mono. It'll cut the amplifier output in half, but at least it'll run.

Also, don't skimp on the amp just because it's powering interior speakers and not a sub. Those amps fail just like lower quality sub amps do. Buy as good of one as you can afford.

Another? You guys know how some songs sound badass in your computer speakers(well mine) and since I don't have an amp for my car speakers(off Hu) will the quality of the sound increase because my car speakers sound worse than my home speakers.

If you can spare some more cash, i'd go with a PDX series amp from Alpine.
