I have a 2007 caravan c/v and noticed that I have an empty cavity for dash speakers, does anyone know what size speaker will fit.
They would obveousely be on the front channel of my RBQ HU, with my frt door speakers, with having 4 speakers on the front channel, can I assume that this HU can handle 2 ohm load?
Thanks in advance,
Terry.
I have investigated with the dealer and found out that I have a low line stereo system which consists of 6 speakers. Four on the front channel and Two on the rear channel. The front left door and dash are connected in parralell, the same for the right side. The rear channel are just the rear 1/4 pannel speakers.
The speaker sizes are:
dash are 5.25" (8 ohm)
doors are 6x9 (4 ohm)
1/4 pannel are 6x9 (4 ohm)
At first I tried 4 ohm in the dash but found that they were cutting out and suspected that the load was too much and needed higher impedance speakers(8 ohm). After researching with the dealer, my suspisions were correct they did need 8ohm speakers.
You can upgrade sound system with two sets of 8 ohm speakers run parallel so it will be 4 ohms at the connection to radio or amp. If you use an amp then you can get away with a 2 ohm load per channel at lowest impedance. If you can replace all speakers that would be best. Coaxial for rear and an opinion would be components for front. Find a 6x9 woofer or 6 1/2 component woofer set with speaker adapter and then a good tweeter for dash and make plastic hole covers to take up space from 5 1/4 speaker. Usually those passive crossovers will stabilize ohms. That will give you great front sound with rear fill.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya
I have 51/4 infinity ref. in the dash wired in series with tweeters to give me 8ohm load at the dash leads. This gives me a combined load dash and doors of 3 ohms due to the parallel configuration. I have replaced my door 6x9's with jensen 3 way 4ohm (I had them already), I want to modify them (6x9's)to bring the total load of the dash and door load to be 4ohms. my HU will run more stable.
My 1/4 pannel rear speaker leads I used a loc to input my fosgate punch 200s, one channel I run infinity kappa coax 6x9's and the other channel running 1-10" p2 and 1-12" p2(both sealed boxes). Both channels are wired in parralel giving me 2ohm load per channel. they are balanced with the inputs on the loc.
My system isn't competition but the HU is clean and thumps nice for an old guy's caravan cargo/van.
I may want to replace the jensen in time but for now they sound good.
In the 2007 wiring, there were capacitors intigrated into the wiring.
In trying to bring the load down on my front channels by increasing the impedance from 4 ohms to 8 ohms at my door speakers by trying to connect the woofer and the tweeters in series, if sucessfull I would have a combined total of 4ohms at each front channel and eliminate the hu from ocationally cutting out at max spl.
I was unable to modify my door 6x9's, instead I connected a 6ohm resistor in series with the posative lead, with that it gave me 10 ohms at the doors.
Combined to give me 8 at the dash and 10 at the doors, in parallel that impedance gave me low 4's.
I know that by increasing the risistance it reduces the spl and alteres the dampening factor but I want to protect my HU?
I think I found the right combination for the time being.
any thoughts or suggestions,
Thanks,
Terry.
