I have an 04 F150 XCab and only have about 8-9 inches under the seat. I wanted to get the 10w7 but then found out that its just a tad to big to get under the seat. So, I'm trying to decide between the 1 JL 8w7 or 2 Memphis MC 10s to start out with. I Have a MTX 801D amp. I plan to use that this week when i buy the subs and then depending on which setup i go with buy another/better amp when i get paid again.
I never thought about the washers, not a bad idea but not sure it will work for what i want. The 10w7's have an 8" mounting depth which means i'd need 9.5-10" of room. The clearance of the backseat is right around 8" which means i'd need 1.5-2" of washers and that doesn't sound like a very safe/stable back seat.
I guess I'm going to go with the Memphis if they will be that much louder. I'm going boston acoustics pro60's throughout so i'm going to need the subs to be as loud as possible.
Will it make much of a difference if i throw 2 8w7's and 2 amps in compared to 1 of each?
Have you considered an Ascendant Audio Atlas 12"? JW was telling me they have a mounting depth or like 6.5 inches. Plus they are badass subs that only need around 300 watts, and they retail for like $150 each. I have a 02 Silverado Ext Cab.. so I feel your pain about the limited room, and I am going to get an Atlas.
