It would be a lot easier to use a standard 110vac amp. Power supplies for running a 12v amp off of 110 are available, but if you are using a mid/high output amp you will have to spend over $100 for the supply.
Be carefull when selecting a supply, if the rated amperage is marked ICS, that stands for Intermittent Communication Service (50% Duty Cycle 5 min. on 5 min. off). The unit is not designed to supply that much power for long periods of time.
: Hi - I'm building a custom cabinet and putting in a car audio system rather than an existing speaker/amp set - figured it would sound better and save some mounting hassle. So, questions:
: 1. Any pros/cons to bottom vs side firing subwoofer? If down, it would be firing down into a 3" toekick area so shouldn't be any airflow problems there.
: 2. I was figuring on using an amp that can work as a 3-way with a built crossover. Any issues with this plan?
: 3. Are there any issues with an 8/10" sub magnet sitting in close proximity to a hard drive? even if I have the system up on a shelf it will still be only a foot or so away from the sub.
: 4. What are the good brands and sources for this equipment? Been 10 years since I shopped for car audio..
: 5. Oh, is a 300W PC power supply sufficient to drive an amp?
: Any other suggestions welcome. Thanks in advance!
