What OHM is best

I'm considering changing out my speakers. Currently have Focals installed and they are 4 ohm. I'm running a Pioneer WC6600 NEX but using the stock JBL amp that came with the truck.

I plan on replacing the amp hopefully this year. Not sure which one right now cause I want to get it installed in the same place the stock amp is.

Just wondering if I would get any benefit in replacing the current front and rear speakers with a lower ohm rating.

 

unfortunately, your biggest problem is the jbl amp. it's tuned specifically for the oem speakers, so as long as that exists, there's really nothing to gain from changing speakers except lightening your wallet.

 

OK That's what I thought.

Do you know what Amp I could replace the JBL amp with, in the same location.

I already have a Maestro DSR1 and the wiring harness to plug into the OEM harness. I would like to do a 5 channel amp.

 

the biggest thing with the jbl amp is that each individual speaker is separately amplified--you have a total of 7 individual speaker outputs from the amp. front dash tweeters, front doors, rear doors, and sub.

so while you could use a 5-channel amp, you'd also need to install passive crossover unit for the front door and dash tweeter. generally, this is going to take more space than where the factory amp is located. alternatively, audison makes 8+ channel amps that could directly take the place of the jbl, but they start around $1500 for only the amp, and take some significant time to program, as the sound controls need to be properly in place to prevent blowing out speakers--you'd be directly connecting to each speaker, and programming the amp to divide the frequencies between speakers.

once you get into aftermarket amps, i don't believe you need most of the maestro functionality anymore. any aftermarket amp would also get RCA cables from the radio in front for the signal.

you'll also need to run new power and ground wiring for any new amp, as the factory wire is not sufficient for power needs of a new amp.


in general, there's no great way out of the jbl system for less than about $2000, and that'd be only for the parts if you're installing yourself. it could quickly close in on $5,000 once a certified installer is needed to do any of the work.

 

I bought this one specifically because it fits in the oem location,

Im gonna be 100% clear, I have not installed it yet and there is very little info if any out there, at least that I could find. I shipped it off to theamplab to have them test it for me and verify CDT power claims and still waiting to get it back with the results. Supposed to get it back next week sometime.

I do have a pic of it in the oem location to show fitment, youd have to get a bit custom with the brackets to make a cradle with some vibration reduction but fits incredibly well

 

If you don’t mind please update the results from the amp lab.

 

Will do, im supposed to recieve it tomorrow, dont know if that will have additional paperwork with it but they followed up with this before shipping it out.

"Doing base testing looks like amplifier is capable of hitting the numbers that amplifier is rated for. I saw about 20v on Ea output (4) channel (not clipping) on a 4-ohm load this would be around 100w. Also, saw about 23v on the 5th channel of the amplifier which would work out to be around 529w @ 1 ohm."

Pretty powerful little amp, hopefully its good sounding too lol, people seem to like CDT though. And their 6x9 2ohm speakers and a wideband would compliment this amp pretty well

 

I was browsing their 6x9 mid bass door speakers, available in 2 or 4 ohm I was thinking of giving a set a whirl. Prices are reasonable too.

 

I considered doing mine like that but was concerned about the heat after I put the trim piece back on.

 

Will you need a PAC Amp pro to process the digital signal from the JBL head unit to install this? There seems to be pretty good support out there for speaker harness adapters as well. I really don’t want to upgrade the head unit so I can keep the factory features and I would like to maintain the integrity of the factory wiring.
I may pair this with the Trail Grid kicker upgrade or just use the

$70 GX328 3-1/2" Coaxial Car Audio Loudspeakers

GX328 in the dash along with the CL-69s 6x9s along with high and low pass filters. The nice thing with the kicker upgrade includes pre-wired filters.

 

I don't have the JBL unit, I'm not sure what's entailed in replacing the amp for that system. I just bought the box and sub for someone and planned to use it but most likely won't (my intentions are to retain the childseat anchors)
