Hello, would like to install in my Astra F ne Car Hifi system soon. I have a few parts for a while and now need some answers to my questions. I have up to now: Woofer: Magnat Transforce 1200 300Sinus/600Max Amp: Axton C408 2 channel 350Watt (as far as I know the sine indication) Boxes: Pyle PDI693 3 way systems 150Sinus/300Max I want to get: Radio: JVC KD-G611 + possibly other AMP (see below) Now to my questions: 1. Where should I connect the 3 way systems ? Are 4×25 Watt sine from radio not too little if still the 4 standard Opel boxes hang from the front 2. Should I sell the Axton if necessary and buy me a 4 channel ? 3. If yes this power amplifier is good what: LINK 4. Where can I put the cables to the radio or the vehicle inside with the Astra F in the engine compartment ? Find no hole to the driver’s room. 5. Fit the standard plug at the Astra right on the radio. Auto is year of construction at the end of 96. Thanks in advance, hopefully someone has for me A I don’t know how to keep going. Oh, well, I’m pretty limited from the budget. P.S. The Amp + The Woofer had a buddy in it. Bass was really very good. If I’m going to get a new amp it should be the same. That’s an addition to question 3!
