I have a 4 channel, 90 RMS per ch. amp. The front door mounting depth in my honda CRV is kinda shallow. I think it's around 2 1/8 at most. I'm havin' a hard time finding any spks. that are shallow enough to fit but can take the 90 RMS. My amp has a high pass crossover. If I filter the bass, can I push a little extra power through? If not, any sugg. on what spks. to look into. Trying to spend less than 100, and I'm probably not a good enough installer to handle components with a seperate tweeter. Thanks for your help.
