Components: Radio: Alpine 9812rb Front Power Amplifier: Audison LR 604 XR Sub-End Stage: Emphaser EA 2200 Subwoofer: emphaser T3 (12 inches) Front: HT: CarPower *The Dome* TMT: still Eyebrid 16er, soon Micro Precision Series 5 The whole in the Golf 3 Just like I now have my front system in, front is full at the Audison, is played with the internal switches, how do I now adjust the ratio of HT and TMT (everyone has their own GAIN controller)? what do I have to adjust first? the HTs run on 4 800 HZ (more goes net at the Audison, or should I go further down? what is a good value?) TMTs now have 60 HZ (set on the radio, gives only a gain control at the Audison) Then the woofer should fit in, it runs fully active, and the alpine regulates the frequency, the pitch is set 80 HZ, the radio can not go further down. Or would be better to set over power amplifier, buddy has got advised over radio, is better. Doors are still insulated at the front as soon as there is Oh and how does it look from the radio with the equalizer? e.g. for Treble, should I change something, lower it higher? or leave it to zero?
