my mom owns a 97 mark 8 and i should be getting it for graduation come may and i have a few questions about the car.

1. is there any space underneath the back seats and if so is there enough to put 2 10" subs there? (if so i wanted to cut a port for each sub where your legs would be)

2. whats under the back dash? it looks like maby speakers or somethen, theres what looks like a plastic cover that hides whatever is up there.

any coments or tips would be much appreciated
 
Replace the deck, speakers and amp with aftermarket. Subs can fit under the deck but not seats. Subs sound better in these cars if they are placed in the rear corners of the trunk and fire to the center line of the car. Has to do with the accoustics of the trunks shape.
 
Specs of what, the amp? Its a JBL POS factory ford amp. Specs of the rear seat? The gas tank would be under there. You could put a fuel cell in the trunk and then put your 5 watt under the seat, but then again you could also put them in the trunk like everyone else. I have 2 12s and 2 1.0 farad caps and 2 c500 amps and an optima battery in my trunk and it still has plenty of room if that is your concern.
 
i havnt heard any other mark systems but i'll take that with a grain of salt laser... Most people won't want to make fiberglass enclosures to fit in the corners..Box's on either side would look retarded aswell.

the jbl amp is in the 140's for wattage, not sure if thats rms or max..Likely max though.
 
just an idea but would i be able to remove the stock amp and put the 2 10"kickers there or should i just say screw it and leave it in the trunk, but keep in mind if i put it in the trunk i want to eventually add 1 15, so would i have enough room with a little extra room to spare?

you can take out the amp rack under the rear shelf. I cut a hole in both the rear metal deck and the panel/carpeting above it about 25"x10". I have my subs firing upward through the rear deck in a sealed box..Dont just cut 2 holes in the deck for those subs as i belive they dont do well in ib setups..If you want to go ib look into image dynamics.

eh, guess it looks ok w/ a 10..W/ a 12" and a 1cu ft box it would look silly..i thought you meant more kitty cornered..Then the box would look ghey. But i'll still disagree that position sounds the best.

That was a $25 ebay box. And he did say 10" subs so.... meh. I would like to have a custom box mad but thats $400 so I guess I will just learn how to shape a fiber box myself. It does not protrude into the trunk much and while not as visually nice as having them under the deck the sound difference more then outweighs the location.

As I have said many times before, my single 10" plays deeper then Sappers pair of 12" subs and the bass is much much tighter. His is louder, no doubt but if I had a second ten then levels would be similar. I have installed a dozen or so Mark systems and 100% of the time the same sub sounds 10 times better in the corner then under the deck. Due to the trunks unusual shape there are too many free standing waves around 30hz and 80hz that cancel out the notes the subs are trying to reproduce so there are dead or overly flat spots in the musical reproduction below 100hz. I have used an Audio Control 1/3 octave spectrum analyzer with a white noise(20-20khz) disc to confirm and tune this. There is a 6-9db drob in those frequencies. While a good eq can help to correct this issue it does so at over amplifying other frequencies and causes the boomy-ness.

As you seem to have found a good substitute is to fire the subs through the deck but most people wont want to make the custom box to fit nor would they feel comfortable cutting a hole in the deck and recovering the shelf in a speaker grill material.

I still have that one Kicker L7 I could throw in there but it won't fit in the corner.

The pic above was a temp setup and it had the boom but no high end bass. When I got back from Florida, I took it out and put my three 10's back in.

It's all about the musical preference you want. If you want a good beat that's clear but not vibrating your eyeballs when looking at the traffic light, then you would want one 10" with a good amp such as what Laser has.

I can't speak for the "firing up through the deck in sealed box" sound because I have never heard it before. I could imagine that with the shape of our back window, the bass would reflect well but idk.

If you have decent amps (with settings) and a good deck with all the needed settings, you can produce some very nice sound. I can make mine sound like I have one 10", two 10", three 10", one 12", two 12", ect. I can also produce the boomer you hear coming 5 blocks away if I have the sub volume up loud enough. As of now, it's set very low and mild and in my opinion, it sounds damn good and it is a three 10" tight beat with boom when the song intends for it. I'm also not into acoustics so three 10's or two 12's wouldn't even be in my vocabulary IF, that's what I listened to.

He's talking about adding a 15" later on so I'm guessing he wants the 5 block away boomer in the near future. Speakers under the rear seats ain't heppenin in these cars. Mine isn't a grocery getter so trunk space is something I could care less about and I don't race at the track so weight isn't any concern to me either. I had to remove my rear tray to get my box in but nothing was on the tray except that $2.00 JBL junk ass thing they call an amp.

To the OP, you put in what you want but don't buy Wal-Mart anything! Buy one thing at a time if you have to until you have everything you need to have the system you want. Check CL on a daily basis. Always someone on there needing money and selling cheap and you can go there and hear it before buying it. That goes for subs and boxes and amps. I wouldn't buy a used deck. Just my 2 cents.
 
So I have a 'tarded question. Believe it or not I don't know much about the stereo stuff,so could a sub and amp hook up to the factory head unit?
 
you'd have to get a line out converter..Vary in price but a decent one will be around 25 bucks.

Hook it up to you rear speaker wires to get signal. Speakers will still work. I tapped into the speaker leads at the amp..Run rca's to amp and ur set..
