Hi everyone! I am using the HELIX V TWELVE DSP and recently purchased a USB-C to optical cable to connect my iPhone 15 Pro to the DSP. However, when I select the digital output from Apple Music on my iPhone, the sound is unbalanced and lacks bass. On the other hand, when I choose the regular output using Bluetooth from my head unit to the DSP, the sound is excellent. Does anyone have any idea what might be causing this issue? Thank you ..read more

My major issue is the power and ground wires. I'm not finding an empty grommet to run the wires through. And I'm not finding a good ground point either. Electrical manual with wiring diagrams for the 2002 van hasn't helped either. I'm guessing I'll need to run a 4 gauge power and a 4 gauge ground up to the battery on the right side of the engine compartment. But hoping not to have to go behind the fender or down through the step well and under the vehicle. If I have to do the latter I...

Fit 6 1/2" speakers in 6"
DIY Mobile Audio Forum

2011 impreza sedan I have 6 1/2" speakers, is it possible to get a bracket that will connect them into 6" holes? When I look at crutchfield or sonics, they say my car is 6 1/2" speakers. But I have them in my hand and I measured them and they are 6", and my 6 1/2" speakers are too large for the default mounting plate. I suppose I could jury rig some plywood, if it came down to that. But I thought maybe someone here has a better idea ..read more

Hello all. I have a Nissan Kingcab with a Pioneer DVD headunit, a Precision Power A600 (150x2) running a set of Morel Maximo 6 components in the front doors, another Precision Power 2200 (200x2) running two Kicker Comp 12" subs in sealed boxes. I know the A600 puts out more than the Morel's are rated but I have the gain on the amp all the way down and the volume on the headunit I hardly ever go above 18, sometimes I'll go to 19-20 but never higher. Truck is a king cab so it's loud. Also... Couple questions possible bad Morel midrange ..read more
