help chose between 2 amps
 

so im finally going to be running an amp to my speakers. i have all new speakers mb quart all the way around. my question is the speakers handle 60w rms and there is two amps i can use. both are identicle inside and out except one is 80w rms and ones 60. initially i thought go with the 60wrms but then i thought maybe i can get away with 80wrms im assuming i wont have to worry about overpowering them since im sure ill lose some of that wattage through all of the wiring by the time it hits the speaker. theres only 25 dollar price difference between the two. so help opinions on which power to chose welcome.

i'd get the 80w one, and just turn down the gain so it isn't putting out full power

you won't lose wattage in the wiring. I'd go with the 80 and turn it down. You'll get better performance out of your amp.

X2 on that ^^^

the resistance in the wiring isn't enough to really matter, but with the 80rms amp, the amp won't have to be putting out full power all the time, which will cause less stress = longer life and less wear and tear

Links to amplifiers? One may not put out rms, or even close... etc.

thx guys i didnt think about the stress part

?????????????????????????????????????????????????? ?????????????????????????

yeah, when it comes to amps, you want a higher wattage amp to power lower wattage speakers. This lets the amp give your speakers their full potential, and keep your amp from burning out. Professional PA systems do this too. :)

Such a dumb thread. You can't compare items solely by price.

cash i dont even understand your questions yes its 60w and 80w rms not peak power they are identicle amps by same manufacturer internally and externally.

Didn't realize I sounded like such a rooster when I sent that. lol

Okay if they are from the same company then the bigger of the two will more than likely do the higher power.

What I was getting at though was which specific amplifiers they were as not all amplifiers are the same.

For example, a Crunch amplifier may claim 50rms X4 @ 4-ohms. Though, after efficiency, voltage drop, etc the Crunch amplifier may only do around 30rms. When you look at a Rockford Fosgate amplifier, they may claim 50rms X 4 @ 4-ohms and really do close to 60rms per channel. Some brands are known to built much higher quality amplifiers in which others can't compare in quality, efficiency, etc. It all depends on the product.

Another example, if you were looking between a 1000rms Hifonics and a 1000rms Sundown amplifier, i'd tell you Sundown in a heartbeat as you are looking at the Hifonics doing around 800rms and the Sundown doing around 1500rms. It all depends.

Neither of the two amplifier that you are looking at may do rated rms power, BUT if they are the same brand from the same line, the bigger of the two will obviously do more power, giving you more room for error. Go with it. Does that make a little more sense as to why I was wondering? lol

safe bet..

lesser known names (budget brands) over rated power
well known names: generally close, maybe over or under, by a little
lesser known names (high quality brands) under rated power

Really? Sundown Labels their shit at 1K rms and give it 1.5K rms? dammm talk about quality for you're money....... Typo?

Manufacturers have been doing this for a very long time now.

Look at old Rockford Fosgate products from the early/mid 90's.

I know I have an old (small) kicker 4-channel amp and the rated RMS power is @12v. The realized power is a bit more with the car running @14v.
