if you wanna attach it to the rear seats you will have to drill small pilot holes where the screws are doing to go as the back of the seats are metal and you require self tappers. Go to B&Q and there will a whole section of self tapping screws.
If you wanna connect it to the box then use self tappers as well

drill a pilot hole in the back the seat first, as self tappers will have trouble screwing into metal

..i take it you have each of the subs a bridged channel? or have you wired them together?
Personally i would wire them together to make a 4ohm or 2ohm load and bridge the 4channel amp into 1 mono channel (should be possible) and connect the subs to that What model of amp is it anyways?

i always thought it ws bad practise to mount the amp directly on the sub box?
something about the amp components inertia with the vibrations??

Amplifier mounting:
DO NOT mount an amplifier on your subwoofer box. I know that there has been a great deal of discussion over mounting an amplifier to an enclosure and many people do it all of the time with no problems but those people probably build good enclosures from 3/4" (or thicker) MDF with extensive bracing. Most people (especially young impatient people) are too lazy to do that and build unbraced enclosures from 5/8 MDF. These enclosures will flex considerably more than a proper enclosure and will likely cause amplifier failure if the amp is mounted to the enclosure.
REASON:
When the woofer(s) moves in or out, the box flexes and therefore causes the sides of the box to vibrate. This vibration is transferred to the amplifier mounted to the box. All of the electrical components in the amplifier have mass. Inertia (an object in motion tends to stay in motion, an object at rest tends to stay at rest) tells them to stay at rest, the box vibration is trying to make them move. The energy from the box's vibration is transferred to the components through the electrical leads which are soldered into the circuit board. All of this will cause the components to break loose and therefore cause the amplifier to fail prematurely. Basically, the amplifier will commit suicide! :-) I'm not telling you this because someone told me it was bad. I've been repairing amplifiers since ~1985. Virtually every amplifier that's come into my shop with parts rattling around inside them have been mounted on the speaker box. It causes the legs of the semiconductors to break (which causes amplifier failure). It causes the capacitors to break off of the board (which can cause catastrophic amplifier failure). It causes solder joints to break on the semiconductors mounted to the heat sink. It causes transformer windings to grind into one another (which causes lots of smoke to pour out of your amplifier). People who repeatedly tell others to mount their amps on the speaker box because they've never had a problem remind me of people who drink and drive and say there's nothing wrong with it because they've never crashed their vehicle. Eventually, in both cases, problems will arise.
NOTE:
Mounting the amplifier on the enclosure also allows someone to steal BOTH your amps and speakers at the same time with no extra effort. It's bad enough to have one or the other stolen but losing amps and speakers (and anything else mounted to your speaker box) is really gonna suck.
