way overpriced you can get it new on the internet or ebay for like 150 with a warrenty. I would not like it for an l7 since it only give 600rms wich is probably for 14.4v so you will get like 500+ real rms. Go better quality especially if your looking to spend 250. Do you have the 1000rms or 750 version? look at MTX THUNDER 801D for 800rms @2ohms if dual 4ohm and orion xtr pro 1000 for 1000rms @1ohm if dual 2ohm voice coil. These are just some suggestions doo some research you wont regret it
