Whats up guys..need a little help getting some stuff together for my Impala. Can anyone recommend a decent head unit. Not looking to go too crazy. I would like to replace the interior speakers with Infinity Capa all the way around. Also looking for a decent amp maybe four channel. I don't want a sub just want a nice crisp interior sound. Also I will need an amp installation kit. Trying to hook it up myself. Hopefully I don't f*** anything up. If anyone can give me pointers I'd appreciate it. Not looking to break the bank. Thanks a lot.
