Std speakers (aftermarket ones at least) present a 4 ohm load, and this is what your deck would be expecting.Originally posted by aydensdad
Hey all you car audio gurus... I have an Alpine CDA-7832 head unit, going through some amps and speakers/sub. But one thing I have not yet added to the system are front speakers. As I am on a budget, I'd like to just power the crappy stock speakers for now until I can afford another amp/speaker combo. So, I connect the front speakers to the HU, and I get crackly, distorted sound from the fronts that gets worse with more volume. The speakers are not marked, and I haven't had a chance to measure their impedance. Would this likely be the problem? Are my stock speakers probably rated at 8 ohms when my HU is expecting 4? Can I do anything to the circuit to lessen the impedance or make it work with the Alpine's internal amp? - Aaron
If you're not planning a huge system, it's valid to run the fronts off the deck, and just use the amp to power any subs. This might allow you to upgrade the fronts now (fronts being the most important part of a sound system, cept your puter), and maybe go for the package deal later with the amp and the sub. Don't forget to get a crossover for the sub.
