Make sure you have a good solid ground. Make sure both amps are grounded to the same paint free metal point. Make sure you are using a good quality RCA cable and that they are run on the opposite side from your power cable. Make sure your rca's arent run near any of the cars main wire harnesses. If all else fails try another amp.

Your tweeters are being destroyed. Either the crossover is too low or the power is too high, or both.

As far as your engine whine is concerned, by far the most common cause is bad grounds, but in an older vehicle it can also be caused by bad spark plug cables or a bad coil.
