mack Unregistered guest | so it is possible to easily run 4 ohm car subs on a 4 ohm home amplifier right. |

Silver Member Username: GmanMt. Pleasant, SC Post Number: 503 Registered: Dec-03 | It depends on the speaker efficiency and the power requirements of the speaker---and the power envelope of the amp. One usually powers car subs with fairly inexpensive, but powerful BASH amps (or something similar). Most home amps are of insufficient power to adequately drive car sub speakers. Car subs don't normally have the luxury of being enclosed in a big box, so to compensate they are generally driven by down and dirty, but powerful amps---also car subwoofers don't have much area to cover. A home sub is usually in a room many times larger than a cars interior. But let me get back to what I said earlier---speaker efficiency. A 4 ohm speaker with 90 db sensitivity will require far less power for the same loudness than one at 84 db's. So one would have to know where you are playing this sub (car or room), what is the efficiency (sensitivity), is it enclosed, loose, or just mounted on a board, etc. There is no easy answer to your question without you supplying a lot of information. |
