alpine 9883

[dkentrepreneur]

I went to a local auto stereo shop and made a deposit for sony xplod gt510 headunit which supports ipod integ as well as USB drive. Currently i have two 12 fosgate subs along with four sony speakers. I also have two amps, one for subs and the other for 4 speakers. The guy at the shop was asking for 380 including the sony head unit and with the installation (including the wires, high low converter). I'm not sure if i already have high low converter installed. I must have if i already have the subs and the amps. I'm not too great with electronics. After doing hours of research, sony xplod has the worst ipod intergration due to slow pace of finding the music you want to listen to. So instead i went to amazon and purchased a alpine cdA 9883 along with the KCE 422i ipod cable. According to online reviews, alpine has the best ipod support and easy access to the playlist. So my question is, how much should this guy charge me for installing the alpine head unit along with ipod cable and connecting my subs amps to the head unit? I really think 380 is a rip off for a sony xplod piece of crap headunit that is with installation included. Also what type of wires are needed and the cost for the wires for installing a headunit and connecting the subs and amps on to the headunit.
BTW i currently own a 02 tl type s.
