Hey I have done a lot of research and have heard that the soundsplinter RL-Ps are amazing for both sound quality and sheer power. I am looking for a setup that will bump and will be heard by people outside of the car, yet will still have good sq. I do not want it to bump so much so that my head is going to hurt after 10 minutes though. I was thinking possibly 2 12 Rl-Ps, but didnt know if those would be too loud for what I am looking for. Maybe even 1 15 Rl-P would work too. I would also like to know which type of box would work well with these subs? What type of amplifier would work well with these different setups? Again I want a system that can have some serious power and be heard with good sound quality, but not so much so that it will give me a headache listening to it for 20 minutes. Thanks for all your help. Mike
