Swez, I am finding the JBL's to be too high pitched and they cannot handle high power at all.
I "played" around with the Amp Gains etc last night, but the speakers are still not giving me what I am looking for

High pitched meaning shrill, overly bright, harshness in highs? How is the mids bass and midrange performance on these speakers? Metal dome or edge tweeters can sound very bright to some folks. Some prefer silk dome for more natural sound. (I prefer silk domes too)
It may have a lot to do with EQ-ing, aiming, location and filter crossover points. Before you dive in and pull them, care to learn some tweaking processes that may prove acceptable?
If the tweeters are pointed right at your head, they may sound very bright and harsh. (beaming) Some Splits (Component crossovers) have built in attenuators to tone down the tweeters. Aiming them above your head or at chest level may help too. Also, too much clipping of the amplifier channels will produce shrill, un-natural highs and sloppy midbass too. Amp/HU setup is key to proper staging and clarity. Very easy to overdrive the amp into clipping with Bass boost, excess EQ or improper gain settings.
Care to give it some time and attention before you throw the baby out with the bath water? Some have reported the Boston's to have similar characteristics. A very good option reported by many here, are the CDT CL-61a's. (or T) They are very natural sounding and at $150.00 a set... the price is a real value. MSRP is normally close to $300.00/set.

Here's a few helpful links on setting up the sound stage on a vehicle.

You may find this very handy and the EQ section is definitely a good thing to review. Just make sure that when tuning and tweaking, keep the volume at moderate levels. Once our ears get a sustained blast of 95dB or more, we lose some ability to detect SQ (sound quality) and have to shut down the system to allow our ears to recover.

Do you have any links to teach me how to do the following:
* Correctly Tune the Amp (Gains, Voltage etc) ?
* Correctly configure the EQ ?

Here's an FAQ that may help you in gain settings and bass tweaking:
http://www.clubknowledge.com/Car_Audio_FAQ/?t3
As for the EQ-ing, it's all done by a well tuned ear or a Real Time Analyzer for a baseline. A friend with a very good ear or a shop that will tune you up with an RTA. It may cost a few bucks to do an RTA... but this tool is the best at giving a solid starting point, then tweak to taste by what you hear and like.

After much "playing around" on the amp, and trying to tweak my JBL's, they still did not sound the way they should.
I have had the Boston Acoustics installed, and they are a million times better...they truley are incredible speakers !!
I used your guides to correctly tune the amp gains etc and it is now sounding fantastic.
I am thinking of pulling out my rear set of JBL's and putting the BA in there too...
The guides were really helpful, and I must say that I have learnt a lot from them...I now understand how to tune the amp properly.
Thanks for your help

Good work on the tweaks. I am surprised to hear how poorly the JBL Comps sound in your application. What was your major issue with them? How was the midbass/midrange performance and was the tweeter giving you fits as well? Try to detail a summary of before and after you installed the BA's.
