Hi guys i have a dilemma on which 0.5 stable amplifier would be the best choice for my needs. I have 4 RE Audio SEx12D4 subs and need to know which 0.5 ohm stable amplifier you all would choose to power these subs. I have them in a custom quad 12 sealed enclosure built to RE Audio specs, made with 1" MDF, and also has 4+ coats of fiberglass resin. I am on a budget and found these two 0.5 stable amplifiers that would meet my power requirements. My car has a 220amp PowerBastard alternator, all 2/0 Awg 100% Copper welding cable, including Big 3 upgrade, an XS Power D3400 Group 34 AGM Battery up front, and a Kinetic HC1200 AGM battery under amp rack in trunk. I will only play system with car running, as of now my sitting voltage is a steady 14.8 volts without A/C on and 14.6 with A/C on. I live in the south so temperatures can reach upward of 104+ degrees. I was wondering which amplifier a Lanzar OptiDrive Opti2000D or Soundstream Tx1.2600D would you all choice to run these subs. All subs are wired parallel to make a 0.5 ohm mono load... Please help!!!!!
