Just finished an install today on a friends car (1994 Toyota Corolla) It consists of the following: Alpine CDA 9884 2 10" Fi SSD (brand new, no options) in a 1.35 cubic foot sealed enclosure BIG 3 (4 AWG) Stock batt up front, Motomaster Elimintaor in the rear 4 AWG wiring throughout Memphis 16-MC1500D @ 2 ohms For some reason, after no more than 10 minutes of test tones (from 25hz to 40hz) at around 75% volume the amp goes in and out of protect mode. All we were trying to do was loosen the woofers up a bit. Car was started, and gains weren't even at full potential. Fuse holder w/ voltage display states that the voltage was around the 11.8V range before it went into protect (cars heater was on, voltage taken at rear batt) We then went out fro a drive, and was listening to a variety of music. To my ears, this system doesnt sound anywhere near what it should sound like. For a 1500rms amp, it seems as though its no more than 600rms to the ear. Now I do realize that the woofers are brand new and aren't fully broken in, as well as the enclosure being a prefab sealed one (for the time being) Can anyone point me in the right direction as to why the amp is going in and outta protect mode? Also, why is it not sounding near its full potential?
