Looking to improve the SQ on a base 2003 Camry. Questions for those familiar with the internals:
- Does the HU connect to a separate factory amp?
- How are the 3.5" dash mounted speakers hooked up with the thin 6X9s in the front doors? Is there a crossover? Paralleled? Or do they run off of their own channels in a separate amp?
- Which would be most cost-effective, yet best SQ upgrade: a. Replace the HU b. Replace the speakers c. Add an amp (or replace the possible factory amp) I suspect the head unit is of decent quality, but underpowered. The ergonomics of the HU are excellent, however.
- Anyone familiar with replacing the front door speakers? Components or low-profile 6x9?
Thanks for any help you can provide.
