Ok just did a basic stereo upgrade. Kenwood unit with rms pwr. High end Kenwood 6" in the doors and 6x9's in rear. Sounds great, crisp but definitely lacking bass. Wanna put a 10" sub box in place of center console. Thinking I should be ok running speakers off deck then running sub off amp. Am I correct and what pwr amp would be recomended for a 10 or possibly a 12? Not a stereo guru, want to keep it simple but do want to do this correctly at a reasonable cost any feedback would be great. Thanks!
