You can find the OEM factory amps for cheap on eBay. Hopefully the wiring is still there and you can just unplug your old one and install the other one.

Does your car have the Hi-Fi option? If so then there should be small little 5.25" subs in the door. While they aren't thumpers,they get the job done. Focal makes an expensive but quality direct replacement.

Another option is to install the rear speaker kit,it helps to fill in the sound but it won't do anything on the bass side.

*Who cares about the radio in the end,the engine and exhaust sound bada55. If you can't hear your engine or exhaust then your driving too slow and you belong in a Chrysler Sebring convertible.
