So, I recently installed some Rockford Fosgate P3 Shallow 10's under the seat in my '14 RAM. I have had Rockford subs (T1 12's) in the past, and I thought they were pretty solid. These things however, are some of the worst sounding subs I think I have ever heard. I thought it was the LOC at first, so I picked up an AudioControl LC2i to help with the bass roll-off. It solved that problem, but man oh man do these things suck. Being somewhat of an audiophile, I immediately packed them back in the boxes and threw them up on Craigslist. Now, the point of my post lol, anyone have any experience with Polk db1040s? The reviews look great and they are fairly cheap right now ($60 on Amazon), so it looks like a steal. Any other sub recommendations are certainly welcome. I would love to go back to the Boston Acoustic G3 10's that I had in my previous vehicle, but I just can't find any. I am not looking to impress the neighborhood teens, just looking for SQ. The days of beating down the block are far behind me. I just noticed that Amazon has the Image Dynamic CTX104 for $129 with Prime Shipping. I see a lot of posts about ID, but I have never heard any. I am guessing the CTX is more of their entry level sub. Also, the ID10D2 version 3 is only $139 with Prime Shipping. Thanks for the help!
