Better amp on lower end speakers is the best way
bad amp = distortion = blown speakers.
The Type X compnets of the deck would be no offence but a waste, the amount of distortion in an internal amp on a deck is 10 times that of a good amp. Good speakers need good power, especially the tweeters, they will blow pretty quick with distortion. Ive installed a lot of systems and I heard $80 set of speakers sound amazing using a clean signal of a great amp and proper set up of the deck. Dont get me wrong a higher end speaker would sound better but the amp really is the key.
