I in the process of installing a new stereo system in my car... I am looking for Sound Quality...

I was wondering if a 100WRMS amp is worse than a 250WRMS amp when tied to the same speaker... assuming the speaker is 75-90WRMS speaker?

Plus... I am looking for a good amplifier, 1 - 4ch amp for fronts and rears, and 1- Mono/2Ch for a pair of subs..(Not looking for a thump just clean bass) ...

I was thinking that a amp that is 100WRMS would be good for the front ...
And anything for the rear...

And 250WRMS for the sub...

I have looked at this JL Amp:
a 500/5

I think this would be perfect since the Vette is small and it has all 5 ch in one unit...

 

Power matters in that you want it to match the speaker's requirements based on ratings and efficiency and you want it to be balanced. For seperates you want 50-100w per channel. For coax, 25-50 is usually enough. Subs vary greatly. A five channel amp is a good idea for your needs. However, I'm not to thrilled by JL amps. Subs are OK but the amps and speakers aren't the best. I'd look at A/D/S, Soundstream, or even Rockford Fosgate first. :cheers:
