i just recently purchased a 1996 straight cab s10 pickup and i am interested in suggestions on what to do with my sound system? i have purchased a alpine head unit model number cda-7893 and two alpine 10" type s subs 600watts max 200 rms and they are dual 4 ohm subs...first question can some one recommend an alpine amp to push these? also can a box be built to give proper air space while not pushing the driver seat up to far? please let me know..thanks

MRV-T420. Pushes 170 Watts RMS x 2 @ 2 ohms. internet price of $235.00, retail of around $400. don't know about the box. hopefully someone else will answer too.

box simple, you shouldnt have to move the drivers or passengers seat at all. If i remember right the subs should have about 1.25cuft. so 2.5cuft for a box isnt too big. it may stretch most the length behind the seats, and you may have to remove jack, etc. but its nothing to difficult. just measure and remeause then cut. all your measure ments witll be outside dimensions so take that into consideration or your seat will get pushed foward. i have an 86 so im not sure the dimensions are valid for you but i think i used something like 26" for height, 7.5" for base, 3" for top and 36" width for my set of Alpine R 10's but i have to rebuild the box because it is only like 1.75cuft.

thanks for the replies i am wanting to build two seperate boxes so the amp can be mounted on the back of the cab below the rear window between the subs.. i have already removed the jack and accessories to it..if anyone else has any suggestions let me know..thanks again

whell seems people have the box covered,,but now the amp.  Since those subs are 2 ohm each, , or 2.6 ohm wired together, it would be better off if you got 2 separate amps.  I suggest 2 mrp-m200 , or 2 mrd-m300, , depends on your budget.

The type-s subs tend to sound there best with 1.25 cube's each, but that may be hard to achieve in your situation.

Goodluck

I wouldn't recommend using two amps for bass because they would be sucking up too much juice causing it to be unstable. if they are d4's, I suggest you wire each sub in series so each sub would be 8 ohm's each, then parallel so they'd be 4 ohms together, and get a two channel amp. If you can, I'd also recommend an Earthquake amp. If not, then maybe someone else can suggest an amp.

Another option for wiring is all in parallel dropping down to 1 ohm. I personally think the lower the ohms, the harder the bass. I'd choose an amp carefuly and make sure it's 1 ohm stable.

I would also say you should have one box so both subs can share the same air space especially if you wire your subs how I suggest it. If you still want the amp between subs, then make a passage way of air connecting each other on the bottom of the box.

Again this is my own personal opinion, others may have different.

i will run them paralell to achieve the 1 ohm load and try to design a box to allow for the amp to be in the middle and allow the subs to share the airspace.. if anyone has any suggestions on the design of the box please let me know....

You could wire the each sub for 2 ohms and just get a 2 channel amp and run each channel at 2 ohms. a kicker kx400.2 would do the job. retail is about 400 internet 270ish

Did you also remove the jack bracket? If so, how did you do it? I would like to have mine removed without destroying it.

To remove the bracket it is best to either cut it out with an airsaw or plasma torch, this way it can easily be spot welded back into place.

Fatdaddyjoe, it seems that you have some mixed up responses up there, but someone was on the right track. You do not necessarily have to have an Alpine amp but if that is what you want, great let's help you find one. You have three different wiring scenarios for your subs.

(1) All parallel = 1ohm mono - a class D mono sub amp tha produce about 600watts rms at 1 ohm mono.

(2) 2ohm stereo - any 2 channel amp that produces 300watts rms at 2ohm stereo. Wire each sub in parallel to make it a 2ohm sub

(3) series / parallel - any 2 channel amp that bridges to 4ohm mono and produces 600w rms. Wire each sub in series - makes it an 8ohm sub, wire the two subs together in parallel, this creates a 4ohm mono load.

Now you have 3 different ways to hook your subs up to an amp and a whole pile of options on amplifiers that you can purchase.

those wiring optiopns are a great help thank you very much..as far as the jack situation i cut it out with a grinder but basically destroyed it to get it out...i plan on putting a small floor jack in the bed for a jack...i think i will go with a 2 channel amp that is 300 watts rms @ 2 ohms..is that the biggest i can go and is that 300 watts per channel? thanks again

the jbl 600.1 will be a wild amp!, definately go for it if its 1 ohm stable,,i think it is.  Someone can confirm that.

something that i learned about the jacks from experience. it does no good to have a jack of any type in the vehicle when you do not have a spare tire.

But while we are talking about S10's and the boxes, has anybody had the metal work done to "extend" the cab to the bed. the protion of the cab that is under the window that matches up to the bed.

Alpine mrd 500 mono block, run the 2 subs in paralell and you'll be set.
