So I have some money to spend on subs. I , just getting a new transmission and going halfs with my parents on the body work from when the lady hit me. I have a 7in clarion touchscreen head unit and alpine type s speakers all around. I have the custom sub box and a kenwood 600watt amp. I want a pair of 10 in subs but not sure what to get. I want something decent I was thinking just finishing off the whole alpine type s since I am looking for something reasonable. I just want to improve my sound not bump my hole neighborhood and rattle my trunk. so let me know what I should get and If I need to get another amp. Thanks
