a) there are no spark plug wires on 98-2004 LH2 cars. However, grit and grime can get into the coil packs and cause problems. It doesn't hurt to pull the packs off, make sure that the spark plug connections are clean, and put everything back together again.
b) depending on the size of your amp, the power feed and gound wires might need to be as large as 6 ga, maybe 4 ga. The positive (red) cable needs to be run straight from the battery. The negative (black) cable needs to be well grounded to the frame of the car. Fanatics have been known to take the negative cable all the way to the battery too. Double check the ground on your head unit too.
c) make sure that the power turn-on signal for your amps is connected to the correct wire at your head unit.
d) run your power cables seperate from the speaker and signal cables.
e) caps are generally a waste of money if your amps are pulling more power than the car battery can supply.
f) a larger alternator will charge your battery faster, but it will not not let you run larger amps. The only solution for power draw is a power supply; the battery. Larger alternators run from 160 amp ($100, a used Chrysler police package alternator) to over $300 for a 200 amp custom wound job.
