[QUOTE="ps2cho, post: 3138273, member: 578373"] Hi guys, I just installed my sub and amp for my new system and its performing really poorly. It sounds almost as bad as the 4" speakers I have do for bass. It makes the "bouncing" sound when the bass turns up the same way that small size speakers do when the bass is turned up. This is my first time doing car audio, so bear with me if I did make some silly mistakes (ASSUME EVERYTHING!) Pretty disappointed and there must be something I did wrong. I was looking for a nice small amount of bass to add to my music, but nothing expensive or super powerful so I chose at DUAL 580w Amp and 2 10" DUAL subs which I got for like $90. I built my own box with correct T/S parameters and here is how it looks: [IMG]http://ps2cho.net/downloads/photos/300TE/wood1.jpg[/IMG] [IMG]http://ps2cho.net/downloads/photos/300TE/wood2.jpg[/IMG] [IMG]http://ps2cho.net/downloads/photos/300TE/audio/sub_box1.jpg[/IMG] [IMG]http://ps2cho.net/downloads/photos/300TE/audio/sub_box3.jpg[/IMG] I connected everything like this diagram I made: [IMG]http://ps2cho.net/downloads/photos/300TE/mysetup.jpg[/IMG] What could I have done wrong?
