Party Bus - Ground Up Stereo Setup Questions

[649RR]

Hi everyone, nice forum! I'm building a party bus and have a few questions on my audio setup...

I am a total noob to audio as I have usually just stripped them out of my past cars for racing purposes but now I'm on a different kind of project. I know these are not top quality items but I have already purchased:

-JVC KW-R800BT double din

RMS 20w x 4ch, Peak 50w x 4ch

-(8 Speakers) Kenwood KFC-1664S 6.5"

RMS 35w, Peak 180w, 4 ohm

-(4 Subs) MTX Terminator Series TNE212D (2 subs in each box)

RMS 400, 2 ohm

My party bus is about 24' long and I assume 8 speakers will be enough to fill the space. My question is where do I place the subs for best sound? Do I need to place 2 in the back and 2 near the front or just keep all 4 near the back of the bus?

What type of amp do I need to power the eight 6.5" 4 ohm speakers? I assume a 4 channel amp and then just run 2 speakers into each channel? Is that even how it works? lol

And for the subs, can I get one 2 channel amp for each box? I'm confused about the impedance and all this other stuff but from what I've researched it sounds pretty critical to my amp choice but I still don't understand it at all...

I've spent way more money on vinyl wrapping the exterior and getting all the interior items than I expected and my budget for this is running super low. That's why I didn't buy better quality audio items than I did. My amp budget is very low...as in $100-$250 total for the subs/speakers and I'll probably buy the amp used locally unless there is an inexpensive new option.

Sorry for the noob questions...

Thanks

Welcome, pretty nice project you have here, I assume you are not going for spl but for loudness and a little SQ, You cna actually split your 2 subs and put 1 in a box (ported) at the back and 1 at the front if possible not in the very front and not in the very back, to power these subs you can just get 1 amp and just run the speaker wire longer . for powering 8 4 ohms speakers, I agree to run a 4 channel amp that is capable of 2ohm so you can wire all 8 of them. i would suggest to get another 2 channel amp for tweeters

Find a 4 channel that will handle 2Ω per channel and find a subwoofer amp that does around 800 watts (a little more is okay) at 1Ω and put the subs in the back. Base isn't localizable and you'll get a lot of cabin gain in that environment so I wouldn't bother with trying to fit a subwoofer box in the front of the cabin.

You'll connect two mids to each channel of the four channel and they will be connected in parallel (positive to positive & negative to negative). Then, connect the two subwoofer boxes the same way.

This is the cheapest most quality amplifier setup I could find close to your budget that actually does anywhere close to rated.

Wire 2 sets of 4 speakers bridging the channels to 4 ohms on this amp. You bridge the 4 channels, so 2 of the channels bridged then the other 2 channels bridged:

Wire both sets of subs individually into each channel of this amp at 2ohms:

this is a subwoofer wiring guide but you can still use it for your speakers just pick the single voice coil and 4ohms and select 2 speakers and this is how it shoul dbe wired per channel on your 4 channel amp

Seems a bit overkill for the subs if wiring at 1, and a lot more wiring than necessary for the speakers. Just my opinion, or at least something to think about.

Remember always opt for quality rather than looks. though, not saying that it is not important but indeed at last quality is what customers cry for...
