Wow great responses. The sub is new, but its been in a the box for two years. I bought it for my GT, used it for about 3 months, then sent it to JL, and they replaced it for me under warranty. The box will be sealed, I don't want ghetto beats like a ported box sounds like. I don't want the boomy bass, just tight low dropping smooth bass. I listen to a lot of dance and rock, so I want it loud and accurate, not boomy and distorted... If I sell my speaker I have, it will cost me less to get a W7, and $100 les for hte box because its s single chamber. If I buy another W6, it will be more expensive but louder, so I dunno. The W7 will play this amp at @ 900 watts due to the ohm load of the speaker, and the W6s will be at only 600 watts, so I would think the added power will make up for the extra sub.
I haven't been into audio for a while, and this is my daily driver (TL), so I dunno what its going to sound like. I am not putting in any EQs or high end crossovers, (they are in the Stangs and my Porsch), so it will be a basic system with the built in 24/dB sloped crossovers, and the two amps. I am going to run 1/0 wire to a 4 gauge dist block, because I have all this shit I was going to put in my Stang. So I still dunno which way to go.
BP you say go the cheapest way, but then not to spend money on a high dollar sub... Well I can get a new W6 for $369 on hook up, retail is $500, and can get a W7 for $600 or $800 depending on size. I found 13W7s on Ebay for like $629, so if I sold my sub for say $300, saved $100 on a box, it would only cost me $229 more for a 13W7, instead of another $369+tax for a 12W6... see what I mean? on your recommendation, you would go with the cheaper setup even though it would be the best sounding one right?
IE, I don't like 10s, they sound like shit to me. I like DEEP bass, not hard hitting 60 hertz stuff... I dunno what the 13 would sound like, but I always liked how 15W3s sounded, so if it was a smoother version of that, I think that would sound the tits!
