ok i just put in my second L7 15 and my problem is when i turn the bass nobe up past the second marker it will cut off i have a zx 1500.1 amp pushing them and 4gauge wire everything worked fine with just 1 L7 looking for some advice.
Wire the speakers in series instead of parallel. Sounds like the resistance of the speakers is too low and your amp is shutting down from too much current.
