Punto subs and amp boot build

Right well basically on ebay you can get 2 1000w JBL's subs brand new for £50 so i was thinking of getting this and getting rid of the sub and ap set up ive got atm as it is not meeting my requirements.
I was then going to build a new floor for the boot out of MDF and the boxes for the subs etc. I was just wondering what amp to get and what wiring kit and whats the best way to go about wiring it and building it all up. Ive also got fusion 6x9s in my parcel shelf and was wondering what every1s opinion on this is wetaher i should keep them or replace them with better 6x9s or components or amp them up or what lol
all suggests and help is welcome
thanks in advance

Junk the 6x9s.

Reagrds to an amp - depends on how much cash you want to spend really.

6x9s arent needed nope,

get a set of hertz comps in the front, amped will sound amazing,

yeah go for the custom build.. jbl 1000 watt subs

run em off a 4 channel amp, for the comps run em off a 2 channel amp will sound amazing

well i dont have a huge budget for an amp but i would like a fairly decent one to get the most out of the subs.
The 6x9s are already cut into the parcel shelf so i would prefer not to just sell them on. So what is the best option to do? upgrade to better 6x9s or upgrade into another type of speaker e.g components?
I already have some components in the front which i think are reasonably good they are alpine with 110rms. should i amp these up aswell?
and how do you think i should structure the set up when i come about building it e.g to seperate sub boxes for the subs etc.

Yes, headunit amps are crap. Get some decent power to them (an amp that'll do 75-150wrms will do nicely) and relish in the improvement. Just make sure the comps installed properly so they can perform to their best.

Yeah cos im sure he has a spare grand for a set of HERTZ Comps when he is buying 2 JBL low budget subs. Sensible suggestiond please someone has been reading Pauls thread LOL
He already has the 6x9's and i believe the holes cut so i have suggested that he use them for a bit of Mid and treble until he can afford to upgrade.
His comps are fine and will be more than enough for now i believe they are 110w RMS which you will struggle to find an amp that will over power them in his budget as most 4 channel amps run about 60w RMS per channel so they are plenty good enough for now.
Right i have been helping this guy and he has seen this amp.

What i would like to know is would the 2 channels be stable bridged at 2ohms as i know JBL can be a bit generous in there stability quotes. And i have suggested that he runs the 2 4Ohm subs connected to make 2ohm's to get the Maximum efficincy out of the amp that he buys. This will not be possible if you cannot bridge the channels at 2ohm's.
Right here is a link to the diagram you asked for.

It is the one at the top of the page. It is a little misleading as there should be two green wires going from + to - on each sub.
Here is the type of the wiring kit you will need.

You will need another 5m phono cable eventually but that should be Ok for now.
Hope this helps

2ohms bridged might be asking a bit too much from that. Unless you kept gains real low and maybe added additional cooling.

For the original poster, if it were me, I'd get that amp linked above and just one of the JBL subs, use one pair for the Alpine comps, the other bridged onto the JBL sub, then if he wishes, use the headunit to power the 6x9s.

right ok a lil bit confused lol sorry
so is that amp good enough or not? and should i go for the 2 jbl subs or not? they ae only £50 for 2 off ebay. Then still unsure about the whole wiring up of these.
As for the components if i was to amp them up....which i will do eventually when i have a lil more cash to spare where will i fit the amp for them?
and for the 6x9s i cn afford to upgrade them now as my firend will buy them for a good price. So what shall i upgrade them to?
I think im going to build the false floor for my boot this weekend...how much should this cost and what thickness of mdf should i use and support it with 1x1's?
thanks alot guys josh

That amp is fine.

Two subs would ideally require a dedicated amp, which then means another amp for your components, which means more money on the ancillaries needed. Two subs would also take up a fair chunk of boot space.

Use the KISS theory (keep it simple stupid).

I have used just one amp to drive a whole system in the past with great results.

right ok then so that amp to power just the subs? or will that be good enough to amp up the compnents aswell.....i was originally going to amp the subs and components up seperatly(with independent amps for each one)
i will still do this if this is what every1 recommends but i will amp up the components after i have done the subs and everything and got abit more money.
also im not to bothered about boot space as i rarely use is at all.
and i am trying to keep it simple lol

I wouldn't use that amp to run subs, this would be more suitable:

Then this:

For your components.

I think that would suit your needs perfectly.

I agree with Paul on his choice of amps i just think that the Guy is trying to keep to a strict budget, but what are budgets i think that i have always doubled what i originally planned to spend. My advice would be to save up and buy the 1 channel amp that Paul suggested that is the one that is best suited to your needs and the JBL amps have very good circuit protection for the price. That means that the amp will cut out before it blows up or blows the fuse.
I have always used 3/4 inch MDF for false floors and i think a sheet of MDF the right size should be about £12.

orite cheers lads been a great help! ill get that amp then eventually get the other amp aswell and that wiring kit u recommended stu and ill use 3/4 mdf for the floor. Should i use that for the sub boxes aswell? and do i need to put anythin else in when building the subs? like filler/glue or w.e u use on the joints? and ill obv colour them in carpet.....how much will carpet be do you think enough to cover the floor and the boxes and also would u recommend any sound proofing in the boot or any where else in the car?
thanks again

also it says 580w RMS when wiring it at 2ohms which u recommended to me but the subs only have 500w RMS....will this not blow the subs or something?

That should be fine those subs will be able o take slightly more than recommended but by having a larger amp you can set the Gain and the other settings down a little reducing your chances of distortion from the amp. If you were way over powering them then yes that would be a problem but not in this case.
I would say that you will probably need 2 rolls of carpet.
Well done on building the box yourself i hope you have the right carpentry skills to do it just make sure that you know where they will be going before you build them.
All i did was seal the boxes with silicon that should do the trick but make sure that it is completely dry before you put the subs in as silicon vapour tends to perish the rubber on the subs. I would port the boxes if you want deeper bass if not then leave them sealed and pack the boxes with wadding and you will have much better SQ.
I have just had a thought the subs that you have got do they say that they are dual voice coil i was assuming that they were single 4ohm that could change things slightly.
