Amplifier matching

shampc · Post by **shampc** » Mon Feb 12, 2007 3:48 am

I'm replacing my 4ch Amp from Alpine MRP-F250 to Genesis Series III 4ch amp. My opinion after searching rms output i think this the correct amp for my component. (i'm shortlisted it among other amp eg..Audison, steg and another Alpine)

But many people say and some of them tested that it is not maching each other, how true it is ?? more ambarass some say got peoples with laugh at me if they know the combi i choose.

need opinion from ice master here as i'm newbie in ice.

thanks in advance.

What do you mean by matching? And what's an ice master?

ice master = (In Car Electronics master)

your initial post doesn't make much sense. what do you want this new amp to match? your component manufacturer, your subwoofer amp manufacturer, what? and exactly which components do you have so we can tell if your current or new amp will work well.

Sorry My mistake. I'm forgot to mentioned my component speaker...It is Alpine SPX-177R aka type X.

From the comment i get is, this speaker is entry level in SQ and it's not mactch if i use Genesis amp whereby this amp is highend stuff...That why i don't understand what they mean.

The reason i change is because my current alpine 4ch amp (MRP-F250) is underpower my component (40wrms 4ohm / 50wrms 2ohm). I'm running active coz i just install PXA-701 and controller...

Are you happy with what you have? Don't worry about what other people think about your equipment, there's nothing wrong with it.

generally, your install ( placement, angle, deadening, etc) will have the biggest affect on the sound. if your not happy with the sound, check there first.

if you're running active, then your giving each woofer 40w rms and each tweeter 40w rms, which is plenty for that pair. your not gunna hear much difference changing amps to get an additional 10w rms.

and as stated above, if you are happy with how it sounds, thats all that matters. most people's car audio knowledge is misconception anyway, so I wouldnt base my purchases off general public opinion.

Sounds like a good match to me...
Anybody willing to upgrade to Genesis equipment knowing full well the capabilities of it with their current equipment... I'd say is off to a good start.

The reason i'm upgrade is because i've done a great mistake (din't check the spec though) on my current 4ch amp which is Alpine MRP-F250 (check this out : http://www.alpine-usa.com/US-en/product ... l=MRP-F250)
The amp rated 4 x 40wrms @ 4ohm but my component is 75wrms..

Because of this stupidity i've make, during installation, i've to bridge using "Y" cable from HU to That amp to get 100wrms then connected to Alpine Type X passive xover. The result, the no separation in sound rather than Loud and mixed sound.

Two weeks ago i've try to match my component speaker (Alpine SPX-177R) to a used Rockford Fosgate old model modified (40i & 100i). It a decent amplifier anyway but dont have variable control (high pass & low pass only.

So now, after i've make a research. I've shortlisted 2 amps which is :
1) Genesis Series III 4ch amp (http://genesis-ice.com/)
2) Steg Competition K4.02 (http://www.audio-system.de/steg/k_steg.html)

Even though the Genesis Series III 4 ch amp is only rate at 4 x 50wrms @4ohm the true power is 4 x 90wrms @4ohm. It's under rated same as old RF amp.

Steg on the otherway is good amp rated at 4 x 115wrms @ 4ohm. But Genesis outperform Steg in term of their reputation in design decent amplifier.

So the decision here is clear...Genesis Series III 4 ch amp..not buy yet since some people say this amp is not match my component speaker. (Decent amp match with normal entry level SQ speaker = not worth it)

The reason i open this thread is to get opinion from Car Audio those with experience. So that i'll not make 2nd mistake with my 1st 4ch amp....

Ok I think your worried that 40 watts isn't enough (or might hurt your components)

Well don't worry. 40 watts is plenty, the only diffrence between 40 and 80 watts would ba about 3dbs. So unless you want it louder your fine running your current 4 chanel as it was intended to be set up.

Ok now to your complaint about the sound. What do you mean by no seperation?

If your running a component set on a 4 chanel, and you use the front chanels for one set of speakers, and the back for the other, you will still have full control over balance. You won't have any fade, but you didn't say anything about a second set of speakers.
