Hi guys just wondering if any of you could clear a few things up for me. I did a search but could not find exactly what I am looking for.
I have 1 set of sony xplod 6 1/2" rated at 250W Max and 65W Nominal (XS-V1640H),
and 1 set of Sony Xplod 6x9" rated at 200W Max and 45W Nominal (XS-GT6930).
And a Pioneer DEH-P465OMP rated at 50W X 4 and wish to put them in my new car when I get it (hopefully a VRX).

Please don't comment on how sh#t sony is like in other threads because I couldn't care less, I'm happy and that's all that matters. :D
I am happy with the current sound but I would like to know how far I could push the speakers in terms of power?, or have I reached the limit already?. For example If I were to get an amp, what would be the most power I could run through them without damaging
them?

And with amps if they say it has a rating of 4x150W would I be right in saying that is the peak power and it really only pumps out about 4X75W RMS. (Avalance AV-430 4 CHANNEL 600W) I know it's cheap but that's all I can afford, any other suggestions on cheap amps are welcome.

I don't expect to have the loudest sound system around and I don't really want too but I would like to get the most out of the system.
Sorry to be a pain in the A#s but I would really appreciate your help
Thanks in advance!

im no expert, so ill just say what im sure is right, please correct me if im wrong.
if there is a gain on the amp (i.e. turn down the volume) then im sure that amp should be fine, just turn it down a little, so whens it at full volume, your
a) not going to overpower the speakers
2) cook the amp

there is this jaycar amp you might want to consider, has a few options and for $200 it doesnt look to bad
Jaycar 4 channel (http://www.jaycar.com.au/productView.asp?ID=AA0422&CATID=24&keywords=&SPECIAL=&form=CAT&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=595)

im pretty sure that amp should be fine as long as its not always on full power, becuase especially with the sonys you'd probably just blow them.

hmm, hoped that helped man

Cheers Paul

Thanks for the quick response mate,
I had a look at that jaycar amp and correct me if I'm wrong but wouldn't that be the same as running them off my HU which is rated at 4X50W.
Is it even worth getting an amp for this setup?
I'm no expert either although I like to think I am. lol

Corrected :P your HU is rated at 50 max, which usually ends up being somewhere around 16rms, the response is 50rms per channel and I dare say your sonys could take this ok, but as far as improvement, you'd get better bang for buck from a speaker change and run it off the deck still.

Matthius

no no, this is 50W x 4 RMS.......the HU's are only about 18W RMS, but they state 50W x 4 to make it sound beefier, in reality, this is a PEAk figure, and the HU is never going to get past 20W in reality, 18W usually, the good thing about that amp is that if you buy a few small subs it can always run those, but im pretty sure the el cheapo will do it aswell.

hope that cleared it up

edit*....haha, what he said^^^^

Thanks guys, I'm slowly learning. :D
I couldn't be bothered buying new speakers so do you think it's worth running a 4X50W RMS amp on the current ones. The speakers can handle this power can't they?
How do you work out the RMS if you only know the Max Power?
The Amp I was talking about b4 only said it was 4X150W Max, I was just guessing the RMS.

The Response 4x50W is pretty much perfect for what you need and want. You will be very happy with this amp. If you want to let the amp have a bit of breathing space (or headroom) you could go the 4x100, which also alows for upgrades to speakers/sub later. A bit more expensive though.

There is NO direct relation or formula to convert between PMPO and RMS or the other way around. The RMS is the continuous power the speaker can handle for long periods, but the PMPO is the MAX specified by the manufacturer for typically less than 1 second. They have absolutly nothing to do with each other. You can only take a rough guess based on rule of thumb.

I think the Avalanche amp will be well suited for the sony speakers you mentioned.

Bare in mind that with the AV-430 you will have an RMS value of 50watts per channel (info. sourced from manufacturer) however, as a coincidence I have personally tested this amp to perform to around 30 watts RMS at 1% THD (just below any audible distortion).

This figure should see that your speakers will run comfortably (being at a higher nominal watt value) and I suggest that you use the amplifier's built in high pass filter at its lowest frequency setting (which from memory is 80Hz). At this setting you will have a system that will be capable of sounding much louder and detailed ( I mean, that's why your amplifing it right?) plus, the speakers will have less chance of over-excursion due to the high pass on the amp.

Don't be afraid of losing bass by using the high pass at 80hz. Thankfully the Avalanche amp has only a 12Db attenuation (not a steep rolloff for frequencies below 80Hz), so you will still hear bass, but it will be slightly limited, and I doubt that the speakers will show any AUDIBLE difference. They will however be less likely to cause rattles and become distorted.

I'm very sure that the speakers will soak up anything that the amp will be able to produce (even at full power) and as long as you set your gain right on your amp, and make sure that you wire the RCA cables well away from interference (pwr cables) you should be very happy with your setup and it will be a major improvement over your existing stereo.

Sony speakers tend to be a little harsh, but they love techno and rock, give a good snap to snare & toms, and love being played loud!!!

Hope I've helped...

P.s. The reputeable manufacturers RMS figure should be at .707 of their "peak" value. However as usual they have been grossly overated (as there is no formal test for peak power), and I swear that they must take use of a bolt of lightning and speed photography to come up with some of these figures!!!

Thanks for the input mate

Sounds like the response 4x50W is the way to go. I'll look around and see if I can pick one up cheap somewhere.

Thanks to all you guys that replied, you certainly helped me out
Cheers

This has helped heaps mate, I'm not a big fan of Doof! Doof! bass so theres no dramas there, I love my rock (disturbed/mudvayne) music and so this setup sounds good.
Appreciate the help.
