analogue EQs add phase distortions to a signal, and active ones also add amplifier distortions. if you're going the analogue route, it's better to use passive EQs which merely attenuate frequencies.parametric EQs are generally better because you can precisely tune both a specific frequency and the bandwith that will be affected making them more flexible for solving both pinpoint resonance issues as well as major peaks or dips in response.
if you're using a digital source though, as mentioned, digital equalization makes a lot more sense. it's available in both parametric AND graphic styles. the entry level behringer does both 32 bands with a 64 band RTA as well as 10 bands of parametric which is 6 bands more than a typical analogue parametric.
it got a very favorable review or two years ago as a "giant killing" solution to speaker and room corrections that greatly improve sound. instead of investing in a hardware unit though, you can ALSO do the same thing with FREEWARE. i don't recall the program, but there's a fairly good one that lets you either adjust your EQ in real time using your computer driving a soundcard or digitize your files for "permanent" adjustments for a specific environment. it would seem to be a really nice way to tune a car system in particular.
the other nice thing about EQ in the digital realm is that you can perform it ahead of your DAC which can be as high end as your budget allows. so you're not stuck with the converters in your behringer (etc.) but can throw a $16k Berkeley Audio Design Alpha DAC Reference Series "ultimate DAC" (according to absolute sound... a year ago anyways) into your chain, or a cheap tube DAC etc. to fine tune your system.
digital EQs have lower distortion plus the flexibility to swap DACs.
here's the enjoy the music 2005 review of the behringer DEQ2496
