im in the market for new speakers for my 4th gen...was seriously considering some infinity's because i like them and found a few good deals on the internet.

ive heard a lot of stuff about alpine so i decided to check out prices, and they seem a little more expensive, but worth a listen

before i go ear testing, i want to know why alpines (generally) seem
have a much lower rms rating (40-50) and peak power (200) than the infinity's (90ish) and (270) ---of course all depending on model

thanks
matt

oh yeah, btw....i still cant figure out what fits 6.5 or 6.75 i see both thrown all over the boards hear (98 with bose)

 

There is no real explanation for why some companies make theur speakers at 10Wrms and some 200Wrms. I bet if you look hard you wil find Alpines at 100Wrms. Im not too sure if that was what u were asking for. And dont concern yourslef too much with peak power.. always and I mean always look at the RMS value.

 

ok well i should specify im looking to use a blaupaunt skyline hu from like two years ago (dont remember power....40 or 45 i think)

just for an expamle:

Alpine Type-R SPR-176A has 8 to 50 rms

and

infinity kappa and reference 605 series both have 2-90

will the alpines really be distorted at high volumes?

 

Realy it comes down to marketing, theyve made people think higher watage is better some compies have bought into it som e han't. By the way your head unit is prob putting out around 10 watts.

 

If you are going to power these from your HU then you should worry that they will blow from under powering them (distortion). And the range for wattage on speakers is what you should really stick to when powering them, but try to power them with close to their max RMS value. ex. for those infinities... and amp that can do 200Wrms X 2 would be perfect.
