Well ive finally came to a halt with my whole car audio system. Go the Alpine M-1000 amp, two sundwon 12s, sound deadening, alpine head unit, etc. Well i wanna continue to improve my system. I have a 2011 Ford Fiesta. And have roughly about 300-400 dollars to spend on anything else that will improve my system. Batteries? Alts? I tried looking for Alts but i cant seem to find anything thatll fit my Fiesta. Need some advice. Thank you
