Alpine Technical Expertise needed!!!!!!!!!!!!!!!!! I have tried everything I can think of to solve the frequency output problem in my car and still have not been able to figure out what is going on. Here is my set up:
Alpine IVA-W505, Alpine PXA-H701, Alpine TUA-500HD, Alpine TUA-T020XM, (2) JL 300-2, (1) JL 300-4, (1) JL 500-1, (2) Tsunami 1.5 FARAD Cap, Yellow Top Battery running 0 gauge to a distribution cap then to the Caps. (2) Sets of Boston Z-6 speakers (front stage is bi-amped), Boston Pro 6 1/2 for the center channel, Boston 12" G-5 Dual Voice Coil Subwoofer. EQ (PXA-H701) is connected via AI-Net and optically.
We have rewired the amps and made sure that all components are properly grounded and ever performed a "voltage drop" test and everything is working properly.
My problem is every time I start my car ('04 Acura TL), my system plays differently. Sometimes my highs are not as loud, or my midbass isn't or my sub bass isn't. The problem seems to be very random and the Alpine techs have not been able to tell me why.
Does anyone have any suggestions as to what the problem is or can you tell me what I should check next. BTW, the amps have been replaced with the new JL Version 2.
