I already have an amplifier going to two mb quart tower speakers. Im pretty sure it is a 2 channel eclipse amp. If I were to add an L5 with an additional mono amp, how should I run the power wire ,and where could I ground the amp to?
No. Unless you have a very large feed allready. Were talking 2ga or better. Other than that run a new feed from the battery to the amp. And make sure you put a inline fuse as close to the battery as possible.
