AUDIOLINE - AL614 Car Speakers (6") $11 Delivered from JB HI-FI
This was posted 4 months 12 days ago, and might be an out-dated deal
So here is some really cheap 6" 80W car speakers. These I imagine would not be amazing quality but for those that are driving around an old 'shitbox' car and don't think its worth throwing a lot of money on a sound system may think this is good enough. Not extremely powerful but loud enough for most.
Im using these to replace an old set of OEM speakers that are crackling like crazy. meh $11 delivered does not seem bad, plus you have your 12 months warranty in case you accidentally play some skrillex.
