25K to 30K (without a HU) a really good budget.
The Verna is a great car to ICE. Nice buy
Fronts: 6.5" components; Hertz DSK165 (6K) or JBL GTO607c (6.5K)
Rears: 6x9" coaxials; Hertz DCX690 (5.2K I think) or JBL GTO937 (5K)
Amp: JBL GTO special edition 4 ch amp (GTO964?) @ 10K or JBL GTO 75.4 (13K).
RCAs: 2K (Audison/Stinger/Twister/Other good ones)
Power wires: 3K (Audison/Stinger/Twister/Other good ones)
If you're not looking really low bass, the 6x9s when amped will do a great job. Every Verna install I've heard without a sub had me lift the boot to make sure there was no sub.
If you want to add a sub, you can add a 10" sub like the JBL GT4-10 (4K) in a sealed box (1.5K) and use the rear channels of the amp to drive it.
