Hi, I'm new to this site but I have 100% positive feedback on Ebay (cya-zya). I'm selling my DSP amplifer and sub that both work flawlessly. I upgraded my sound system and have no need for it anymore. I have all bolts and brackets so install will be simple. I removed them both last week and they both worked like new. Zero issues. I just saw that the DSP amp sold on ebay for $305 plus shipping. So I'm thinking $425 shipped for both. I can email you pics if needed. My email is [email protected] I'm located in Bristol CT if pick-up is an option. I'm going to give it week or so one here then they will go on ebay, Thanks for looking Rob
