I def want to get a D-Class Amp ...i just dont know which one will give me the best result.
1- SWS-8 (4ohm) in Stereo with an Alpine D-Class 2x150w
2- SWS-8 (2ohm) in Series with an Alpine D-Class 1x300
Or what else...?

Wow ... i didnt know the OE underseat subs were set between 200-250hz ...that explains alot. How would I change the crossover output from the OE Amp with just an additional Amp and a LOC from Technic?

4ohms in Stereo (2-channels) = 4ohms total impedance per channel
4ohms in Mono (single channel/Parallel connection) = 2ohms total impedance
4ohms in Mono (single channel/Series connection) = 8ohms total impedance
2ohms in (single channel/Parallel connection) = 1ohm total impedance
2ohms in (single channel/Series connection) = 4ohms total impedance

The amp chosen to drive the SWS-8 is determined by the total impendance to be driven per channel.
