I have a Diamond D3 12 duel 4 ohm in a custom Alpine Inclosure and a Kenwood 1000 watt amp for sale. everything is in perfect working condition and sounds really good and hits hard to boot. If you are interested send me a PM and this is a pick up only, I'm sorry but I will not ship. I live in western part of Indiana. I am asking $200.00 for both but feel free to make a serious offer. Thank you for your interest.
