Right, Back to front, Power Cap, no. These are gimmicks to be honest, a 1 farad power cap is a massive amount of energy about 100Amps !, not needed. However for a Sub, then you might need one to keep a power continuity. But a 0.5 or even 0.25 farad cap is sufficient.

Right This is how to do it, and dont worry bout the head unit, one step at a time cause a new head unit will run like this too.

My Amps are both in the boot, screwed to the back seats. Now, Power and earthing cable is important, use thick cable for amps, they draw so much current you wouldnt believe. So for the power, you will need either, 2 cables of 0.75CM copper thickness, or 1 cable of 1.25CM copper thickness. Directly from the battery. It is important, the thicker the better (in this case anyway!)

Then also you will need the same diameter in Earth Cable. Then, run the phonos from the HU, to the Front components Amp, then from that amp to the sub. There should be an input and output on the amp. And there is no compensating in sound, amps and Hu's are preamped for signal, so you wont lose any. But the best thing is to put Either the better quality amp first, or the one powering components, Not subs. (cause they filter signals)

For the speaker wiring, you will have to follow from the components through the door, then take the cables to the back of the car somehow!!!, wherever you feel is best! But i would advise that the most important thing would be to upgrade the backs aswell, cause then you can do the wiring job all in one! (time saving)

For the components, You will get, (and i mean this) a HK equivalent sound from a good set, For loud sound, go for Kappa Infinity fronts, these include 2 drivers and 2 tweeters, £165.00, but well worth it. You will get a very bright sound from them, plus they can take a hammering, however. . . . I did blow one of my tweeters due to a musical hitch, to replace it, it would have cost me £80, no way, so i bought a pair of caliber tweeters £50, they dont sound as good as the infinity, but can take more of a beating.

The tweeters are the most important thing, they are funny bits of equipment, they are made of a plastic material, and if you want to know how they work, ask and i will tell. But they can withstand upto 200W rms, but with amps not being able to do this, they usually blow first. The only reason the kappas are good is beacuse the tweeters, and the fact that the main drivers can take a beating, The drivers are not nessasarily (spelled wrong) the best sounding.

Hope this helps, fire away, so they say. If you have any more queries.
