Hai guys

Before I get started on the speakers/amp and my question I have a 2002 5.2l v8 single cab xlt triton f-150 which I absolutely love.

anyways, onto my question

I currently have two 10' 07 crv kickers hooked up to a Zx750.1 kicker amp in a non ported case (I got the system for free from a friends friend. Both the kicker subs were blown so I replaced them with 07 4 ohm both running parallel wiring). I just got another 10' 07 kicker and I know I can't run it on my current amp with the other subs because that will blow the amp. my plan is to double amp it with my extra Jensen 400.2 and power the one speaker alone and the 750.1 power the two, but I'm unsure if my battery/alternator would be able to sustain enough charge to power them both or if I need to replace both before I begin this process.

Its gonna be temporary till I can save up the money over the next year to have the interior redone so I can have 2 12' kickers in a band pass enclosure and four (or just two) 10' kickers in ported (or sealed) wired up in my truck.

 

Let's see here, first off its a 5.4 not a 5.2...

And I'm not seeing how your taking two dual 4ohm subs and wiring them to a 2ohm load for that kicker amp to get the most out of it, with two dual 4ohm subs you'd only be able to wire them to a 1ohm or 4ohm final load.

That jensen amp is rated at 200rms at 4ohms bridged, so you'd roughly see about 1-125rms of clean power with no current drop (yea those amps are terrible).

The kicker amp is fused at 80amps and the jensen at 25 (according to specs online) so you'd be at 105 amps total load at max draw. If you did the big 3 it'd help but you'd still probably have to deal with some dimming issues if you really tried to crank it up to make those subs loud, if you decided to do this.

I wouldn't do this, because for one it most likely won't sound good. Two different amps running at different power levels, two three different subs with one most likely not having the same airspace, and chances are if your friend blew the others the box those two in probably don't have the right airspace either. Plus the kicker amp will supply rated clean power, while the jensen amp won't even come close.

And technically you could run it on your current amp, three dual 4ohm subs can be wired to a final 2.7ohm load (crutchfield wiring diagrams to the rescue) but you'd only be feeding each sub roughly 200rms a piece, about half of the rated rms they can take.

As for your future plan of running a bandpass box and either a sealed or ported box at the same time, sounds like a bad idea. For one thing, bandpass boxes don't sound too good in these trucks with the cabin gain (I used to have two kicker crv's in a bandbass box built to spec, sealed and ported was much better), and you'd need to do some extensive tuning to get it all to flow together, and in the end it just wouldn't be worth it because the sound you would gain would be lost during tuning unless your just going for loud and not sounding good. In which case those subs aren't the way to go.

And on top of all this since your a single cab, unless you plan on only leaving the drivers seat, none of that is going to fit. You'd be much better off getting selling those kicker crv's, trying to sell that jensen amp, and getting some quality shallow mounts like the alpine type r shallow, jl 13tw5, or the stereo integrity bm's in the right size box.

 

Thanks for the insight :o I've been trying to understand sound systems (I'm a music producer and only have a clear understanding of that field) and a vague knowledge from information I could find on loads of the speakers

What would be the best way to get the most bass I can out of my single cab? My original plan was eight ten inch subwoofers. I have been trying to keep toward kickers because I have enjoyed these sub woofers for a while now. Also should I stay with 10's or upgrade to 12'

 

Your major problem is going to be space, and possibly your budget. I doubt you could get proper air space for eight 10's. Two quality 12's in a proper box would sound better than 8 10's in a poor box. I would forget about ported, the airspace just isn't there for them.

You could always do a blow thru, but that'd be a pretty extensive and expensive install.

Kicker makes good budget speakers and their high end solo x's are pretty nice, but they aren't going to be the best route for you to take.

If you have some extra cash you can pick up two shallow alpine type r 12's for around 600, they're single 4 ohm subs so you can wire them down to 2 ohms which would be perfect for your amp. I have one running at about 300rms and it can get loud, but still sound good too. It performed better than the standard size type r which is why that one got redesigned. Plus the 12" version only needs about .5cf sealed, about half of what one of those 10" cvr's need.

The subs I can think of that'll work best would be the Alpine type r shallow 10 or 12, jl 13tw5 (but very expensive and about the same as the alpine), the stereo integrity bm series (new production isn't out yet, but amazing subs), or maybe the Sundown SD-8 (only needs about .25cf sealed, get's loud, under 5" of mounting depth, but they'll take some power).

I think either shallows or some high powered 8's will be your best bet because of airspace and mounting depth constraints but if you go measure the dimensions you have I can probably come up with some other options for you.

 

Would you like the current dimensions or just the length between the seats to the wall?

 

The dimensions of the box you have now and/or the max dimensions of what's back there would be helpful.

 

My rough dimensions from the seat to the wall 11 and a half inches taking of a couple ticks because its dark, floor to the part that comes over from the back wall (hard to describe. I'm not sure if its standard in other trucks or if it just flat or has a point where it comes out a bit like it does in mine) is 13 and a half inches and from the wall to wall is 64 inches

It was kinda difficult to get back there being 6'2 haha

 

Just figured I'd throw this out there, but I had 2 JL Audio 13 1/2" tw5's behind the seat of my 02 reg cab like 3 years ago powered by a JL 750/1 and it was a BEAST.... I have since gotten rid of that truck but moved the subs to my new truck. I still have the custom sealed box that was spec'd by JL Audio just sitting in my spare bedroom.... It is a very well fabricated box made specifically for those subs, so if you DO end up going that route feel free to contact me as I am willing to unload that enclosure for a VERY reasonable price.

 

Also, I am 6'1" and had plenty of legroom left...

 

As a matter of fact, my old truck is veiwable on my profile... You can see the subs in the box that I was referring to.

 

Yea I think you might be better off with some shallows or maybe some 8's then.

And that guy said he likes his jl 13tw5 shallow^ in his regular cab which brings me back to the alpine type r shallows. You can get two of the alpine's for the price of one jl, and after reading countless reviews before I bought mine almost everyone agreed on that the alpine gets a nice bit louder and can sound just as good.

 

You are very correct there... The Alpines are much more affordable. I cant say that I've had the chance to hear both types of subs in a side by side comparison, let alone be able to hear them actually installed in similar vehicles with correct wattage... But I would LOVE to be able to! I've always been an audiophile since I was about 15. LOL
