pioneer GM-3500T amp
has anyone used these amps before are they good value or priced accordingly
id like to know if they are good and maybe to add this to the new stereo in my ute
the head unit is
pioneer DEH 4450bt
and my spilts are
alpine sps610c
80w rms 240w peak
the amp is
60w rms per channel
and 200w peak per channel
Those amps are fine but personally, I'd be buying an amp rated at 80Wrms or higher for your application. You'll be running that amp at it's limits and will probably end up damaging your speakers.
what amp do you recommend that is rated at 80w rms x2 then
ive been told kicker 70w rms x 2 but its a little out of my price range
i prefer to keep it under 150 for the amp not including wiring kit
what is the difference between running 2 ohm and 4 ohm as the amp stated above can run 85w rms at 2 ohm
how does under powering speakers damage them
by running this amp it will triple the power im putting into them
as they are just running straight off the head unit atm

I don't recommend amps, I just advise what would work better.
Speakers have an impedance which can't be changed. In car audio it's generally 4 ohm. So you connect a 4 ohm speaker to an amplifier, the amplifier will be running at 4 ohm.
When you use an amp that can produce less power than the speakers can take, people end up turning the stereo up until the amplifier starts clipping (distortion) which then causes excessive heat in the speaker that can damage it. Amplifier distortion is a bit harder to hear than speaker distortion so I prefer to recommend more power than required to avoid amplifier distortion in the first place.
im not a big fan of amps ether but everyone keeps saying that my stereo will blow up because of inadequate power from head unit to speakers
I meant I don't recommend amp brands (as I work for a brand).
I wouldn't build a car stereo without an external amplifier, head unit amps suck.
what amps are 80w x2 rms
and are they in my price range of $150
i would to use ether the pioneer or the alpine brand as thats what i already have in the car
i dont see how under powering a speaker is bad for it as much as over powering it
i.e if u under rate an engine it will last forever where over rating it you rebuild it every 30mins or run time
i know an engine is an engine and speakers are speaker but i would of thought under powering them was good for them
so at this stage im a little confused but willing to listen to your comments
im also beginning to wonder if you can reduce the power that an amp produces
i.e could i make this amp
http://www.pioneer.com.au/au/product...00T/specs.html
produce an 80w rms ?
but in saying that isn't an amp better than no amp
i dont plan on having a big loud stereo all im aiming for is clear sound so because im not going to have it super loud would the smaller amp cut it
as the rms is a constant running level
correct me if im wrong but the way u increase volume is by increasing volts?
therefore by putting a 60w rms amp on the stereo it will be louder anyway
im not trying to be smart i am just confused about the low voltages as to high i.e putting a 100w rms amp on these speakers is good for them ?

I already explained above how having a lower powered amp can damage speakers. Read this if you want a longer version: Click me
You don't need to "reduce the power an amp produces". An amplifier's rating is the maximum power it can make, it only makes that if you turn the volume up to that level.
RMS is not a "constant running level".
Yes, the amp you originally chose will be louder and clearer than the head unit. What I was saying is that IDEALLY you want an amplifier rated to the level of the speakers or higher so that you don't overdrive the amp and cook your speakers. Read the above link to have it explained in more detail.
how does using an under powered amp to power speakers "blow" up the amp if it can only put out 60 w rms isnt that all that it does
how long would i get out of the amp if it was to blow up? minutes? hours? days? weeks? a year?
if someone could tell me an amp rated at 80w rms under 150 dollars that i could look at purchasing and adding to my stereo
or if the pioneer 400w one ive have listed will be sufficient to clearly run my speakers at listening volume in a UTE not doof doof from 100m away all the stereo is for is listening to music while driving

Just buy your original amp, if you don't turn it up until it distorts (which you claim you won't), you'll be fine

for $150 u'll b looking in the 2nd hand catagory pretty much but if u can stretch ur budget 2 around $250-$300 u'll easily get urself wat u want. but that pioneer 5500T amp would b much more than enough as long as u set the gains correctly.

********4 Sale- 2 x 7' Pool Tables********
ive settled on the response precision
AA0450
2 x 80w rms
$119 at jaycar
its the right size for my speakers and ive been told that they are a pretty good quality amp
The pioneer 2 channel amps are fail for running splits , they only have LPF on them which is completely useless unless running a sub.
Right click save as . .
i did a complete back flip this morning and bought a kicker zx200.2 amp
now i need to learn how to tune it does anyone have a simple method to tune the amp
to suit splits?
