Re: How to tune a power amp?

Thanks for your advise. It seems like tuning the sub is much easier than
tuning the amp for front speakers.

You are spot on. Actually i love the way it sounds now. But you know, i did
not perspire changing the sub amp and the new sub. So i thought something
must be wrong. I saw my installer spent a lot of time tuning the amps for my
front and sub. So i guess i gotta tune my sub amp too. Right now, they are
at factory settings and it sounds great. The question is, can they sound
better? How can i know if the sub amp can sounds better?
Thanks.
