Obviously not "what are the most expensive ones", just "what are the ones people like best". The amp is very important. JL makes a nice sub amp (500.1) - are their component amps good as well? What other brands are quality amps with good hardware and configuration/tuning options?

What are important characteristics for a good amplifier to have?

With a nice set of component speakers (probably Polk Audio or MBQuart) what should one use to power them?

I have a JL 450/4 running MB Quart comps at each door. I am very happy with the sound quality and power. I personally don't think it much matters which amp you use for the comps as long as it provides enough clean power to match your bass setup. I am using the JL 450/4 mostly because it matches my JL 1000/1 running my subs. My setup has the amps exposed so using the same brand that matches looks better (same size too).

Would the 450/4 be too much power for MB Quart Premium PCE-216 components?
Also if I was only going to run a 500.1 JL with a smaller sub like a 10W6 or 10W7, would that be underpowered against the components?

Thanks.

1. Yeah, 450/4 is too much. I would use the 300/4.
2. No. That would be in line if you use a 300/4.

okay thanks, i appreciate your input. i think the only store around here that sells JL is Tweeter. I've heard some people say they are not the kind of place you want doing the installation though. Maybe I will buy the hardware there and either attempt to install myself or have another place do it.

If you're having it installed, I would find an install that can get you the JL equipment you want. I wouldn't want to buy at one place and ask a second place to do install because if something goes wrong during the install, you're stuck doing leg work.

ok thanks for the advice. I will try MyerEmco, I think they sell JL and i know they install.
