Hey guys,

First of all, here are my goals: clear, high fidelity sound quality for trance, classical, rap, and rock. High sound volume is not a necessity. Basically, I recently purchased some equipment from a friend and installed the head unit, front, and rear speaker setups. I still have a sub to install, but now I am having second thoughts.

I am in search of recommendations from generous car audio experts. (my current system is listed near the end of my posting) General recommendations are welcome and here are some of my main questions:
1. Would my sound quality improve if I purchased a four channel amp to power my speakers? (I do not need high volume and already have a 27 watt rms head unit)
2. If so, how much rms and peak wattage should I go for?
3. Any product recommendations? The Profile Profile HA 1040 seems like it might be perfect but the price makes it seem too good to be true, any experience?
4. If I upgrade the amplifier, would the Infinity Basslink sub work well with the system?
5. If so, where should I mount it?
6. If I upgrade to a strong 4 channel amplifier, would my little Honda Civic 2001 coupe be able to handle the load? Also, would it handle the sub woofer's load?
7. What kind of additional parts do I need for installation (such as wire and wire type)

Here are my current system details:

The sub will just add some "bump" and lower end frequencies that your comp. and co-axial speakers can't pick up.

That system with the current sub choice is strictly SQ, but at a budget level I'd say...Not that it's not good stuff, just not JL quality SQ (or anything of that calibur).

Thanks for the advice, what kind of modifications would you recommend for my system? I will look into changing my sub choice. Also, I am looking into an Orion 8004 100 watt rmsx4 amp for the speakers. If I purchased something of that power, would I hear a distinct difference in sound quality compared with my current 27 watt rmsx4 hu? If I do upgrade to an amp of that size, will my little Honda Civic's electrical system be able to power this system?

Thanks so much!
