Baliw naman pala ang 1st installer mo. Based on what you mentioned, it seems he only used one RCA cable and used a Y-connector to split the front signal of your HU for the seps and subs. The 2nd installer added another RCA cable so the front signal goes to the seps and hopefully the sub-out signal for the subs. Would you check if you can control the volume levelof your subs using the sub level control on your HU. Paki confirm muna bro before I continue. Let's see if we could do something 1st with the install before you spend for a new amp.
