Do you have to add an amplifier to modify your car's sound system?

Generally entry-level speakers, the host can be pushed to listen to, but added amplifier will be a little better. But have to consider the cost-effective, after all, entry-level, quality is not bad host has been able to play out most of its potential, the remaining point on a little bit of quality amplifier, plus wires have to be about 2,000 ...... so, cost-effective ah cost-effective. Modified audio common equipment: speakers, amplifiers, bass, amplifier's role is to amplify the weak signal from the source or preamplifier to promote the speaker sound. A good sound system amplifier role is indispensable. Host push factory speakers performance to achieve the best 70-90% of the factory speakers is good, the factory speakers are not modified plus amplifier effect is not great. If you change some good speakers, the factory host basically can not push, the effect is not out, completely with the car tuning store to listen to the prototype is two different things, so it is still the most cost-effective amplifier. Mainly depends on what speaker sensitivity is how much I think the sensitivity if the original host in 92db93db push properly, even if you add the amplifier difference is not heard, if the speaker sensitivity in the 90db or less, that really is the original host is not too much to push the need to add the amplifier.
