At $150 or more each for those Pioneers, there are certainly less expensive options available but none that will match the factory wiring in a Firebird as well as the eD subs. You will be leaving an amplifier channel on each side unused by installing SVC speakers.
Check with Ian (KEE AUDIO) about getting some CDT speakers that might be less expensive than the Pioneers with comparable (or even better) sound quality.
