Currently, I have Infinity Kappa 692.5i rear speakers and 462.5cfp front speakers. I am not looking for a super system, but rather something that sound decent. I plan on using a quality head unit as well.

The fronts are rated at 60 watts rms and the rears are 110 watts rms. Both are 4ohms impedance.

 

check out an eclipse or alpine 4 channel. something with about 75-85x4

you can always turn down if its too much for your fronts. i would just def say, make sure there is a high and low pass x-over on each channel. you'll want to run the fronts on low pass about 400hz, and run a low pass on the rears at about 70hz. they cant handle that deep sub bass, but you will def get a round sound.

 

just get a 350rms 4 channel amp. you notice the difference right away. once tuned it sounds way louder. I use to listen to music on my deck at like 20-25 (fairly loud). Now with my amp I listen to it at like 15. Makes a huge difference. 20-25 now is ear bleeding, can barely hear myself talk.

 

Would something like a Infinity Reference 475a work well?

 

Or JVC KSAX4504?
Or PowerBass ASA-600.4?

 

I ended up getting the PowerBass ASA-600.4 and mounted it in the spare tire area. Post to come in the future.

 

Still have to fine tune the settings, but now will get loud without distorting.

 

hours of tuning distortion is alot of fun!

 

I realize that the tuning is done by a very unprecise device (ear), but can you provide any tips on setup?
