I want to get a really nice system for my car. At first i was looking at 2 JL 13w7's and i was gonna run them on 2 JL 1000.1's. I am willing to spend what it takes to hook something like this up but i was looking at some other subs and was wondering if they would compare at all to the JL. I looked at the Orion HCCA154's, Alpine 12 type x's, FI BTL 18's, Memphis CM10D2's. Are any of these close to the w13? Are there any other subs out there that are better or similar to the JL 13w7? After the JL's my second choice would be the Orions. Please somebody who knows a lot about this stuff let me know what you think.
