looking to upgrade subs. the amp i have is a elemental design nine1 1200watts at 1ohm at 12volts.$300 max per sub but dont want to spend over 500 total. iwant to power 2 subs 12"s or 15"s. looking for sql. right now i have 2 15" cvr and they cant handle the power i have. i heard of the rlp are good but if i only have enough power for the 12s will they be louder than the kicker 15s. open for suggestions
