the subs have absoulutly nothing to do with if you need a new altenator, cap, or anything else...that all depends on your amps...as for the subs i'll leave my opinion out of this, enjoy them...what are the specs on yoru amp
um...yea yur gona need a few alts and a few bateries, but no caps, caps are worthless, id rather put my money in an alternator...a cap is like a band aid, but a new alternator will fix the problem...bahn stuff draws serious power...thats like 5000rms...thats too much power...you really don't need that...watts DON'T matter when it comes to loudness!!!go witha X.XX 15" or Brahma 15" or IDMAX or sumfin that won't require 5000 rms to get the same output, o yea and audiobahn stuff sounds terrible...it can get loud though...in my opinion audiobahn is a waste of money, they are unreliable, and draw way too much power...
Cmon, stop telling ppl about RE, I want to put Audibahn ppl to shame. As long as you enjoy it go for it. Rember you'll have to listen to them on Good and Bad days... Headaches just eat up loud AudioBahn bass.
