Hey Man, You can put upto 6.25" speaker in the front without any problems. The quality of the sound is going to come down to the quality of the speaker. Most autobarn / super cheap brands (poineer, kenwood) will do a great job if you just a "better than factory" sound Personally, I go a bit further to achieve "awesome sound". If you want to play in this field, be prepared to drop some coin. Brands to look for include: Hetrz, German Maestro, Response (jaycar) Just remember, this is a person view, other people may differ in there views and there is no right or wrong answer!
