RMS value question

[joshua.watson1987]

Hello,

I got a head unit that does 4x30W rms (4x52w max)

Now will 100W rms speakers work ok with this or should i get 30w rms speakers does it make a difference at all

Even that 4 x 30 is pushing it. They quote it at 14.4v and quite a high distortion rate.

Those speakers will work, but to make them sing they need power. If you plan on amping near the future, then go for it, if not then get lesser powered speakers.

Well i will be amping them in the future yea but would i get better sound from the ones that match the rms or the ones that are over

If you're gonna amp them in the near future, then you may as well just buy one set of suitably high WRMS comps over buying a low WRMS set, then having to buy another set of comps when you come to amp them

Hi guys

OK, be warned, having higher power rating on your speakers on a lesser powered amp could cause meltdown of the amp and damage to the speaker drives. As a rule of thumb, you should have more or at least equal power from your amp than your speakers can handle. That or make dam sure you don't crank them up to max.

I can run through the calculations if anyone's interested but it's techie geek speek and might bore people :idea:

So, either buy the matching speakers, but TBH you want even them amped as the head units never deliver what they promise!

Or go the full hog and get the monsters but do not drive them hard.:slayer: As soon as you hear any kind of distortion, back off a little. Get the amp fitted later. As long as you don't go mad with it, you should be OK.

Yeah, headroom is a good thing If its the opposite, then keeping the gain low is a good idea
