Hey I recently purchased a pair of Kicker 10's, ported I think, and a Rockford Fosgate Prime R1000-1d, a 1000 watt amp. I have this set up in the trunk of my 2003 Toyota Celica hatchback and I heard hatchbacks are great for subs. Im am very new to the sub world and was wondering how to make it sound the best its capable of. I have as adjustment knob under my steering wheel area which controls the bass level I believe. I also have Alpine Sps-600 240 watts peak and 80 watts rms type-S speakers and a Sony DSX-s100 with ipod tune tray inside. On the deck settings I have sub level at zero and I control the bass level with that adjusment knob. The place I had the subs installed said to have the sub level on the deck at zero and just use that knob so I do. But I find i want more kick to it but of course with out blowing the subwoofers. And the other day my friends said it should kick harder. I put loud on the deck settings and found it does seem to kick harder as well as adjusting the sub level but I fear that it will blow them. Any suggestings on what I should or could do to make them sound prime would greatly be appreciated.
