Got my box done yesterday, got my sub in today. FI Q 15" D2
Its running off a DLS A6 1200watts @ 1ohm.
Box is about 4.05cf after displacement, tune to 32hz.
When i play it about 1/2 way, when the car is on or off, on mid high level, the sub stops working. Than i lower the volume, than it plays.
I dont know if its my amp, or my tunning.
Im not use to tunning vented enclosures...
So any advice is appreciated!
I dont know where exactly to start my tunning on my amp, and my crossovers on my HU.
ULTIMATE series A6. A 1 ohm stable monoblock that´s perfect for SPL. Extremely powerful power supply. The output power in 4 ohms are 500 thrue RMS watts. A cooling fan is built in but the amplifier also provides a built-in fan control for external cooling fan.
Built-in, variable 50-125 Hz low-pass filter for subwoofers plus a 25 Hz subsonic filter with an 18 dB/octave slope. Dual power terminals where you can connect dual power feeds or a DLS Power Cap. Extra features are a phase control variable 0-180 degrees continiously.
A remote sub level control is included. Adjust the sub level and phase from the front seat!
