First let me say that I have found tons of advice on here from some really helpful folks, Thanks!! I currently have a Sony 7000 with a TM400X4ad, 2 sets of Kapps 62ix's and one set of Mmats 601cx's. I have the HU connected to a set of Kappas in the TP pods using the rear channel of the HU. I have a set of Kappas in the upper fairing connected to the front channel of the RF amp, the Mmats in the lowers, connected to rear channels on the RF amp. I setup the RF amp per instructions for clipping. I have the HU HP around 80 and the RF HP set around 100. Questions, does this sound like I am in the right ballpark concerning setting up? Also since the Kapps are at 2.5 ohms, I had the HU on 2 ohms first but the sound was really low, I decide to switch the HU to 4 ohms and it now sounds better, louder...... much louder with the HU set at 4 ohms.......they are as loud as both sets from the RF amp? I thought I would get more at 2 vs 4ohm settings on the 2.5 Kappas. Thanks in advance for any advice

 

 

Forgot to ask if I needed a DSP with this setup

 

The head unit power shouldn't be used. Regardless of what impedance setting you use the deck power distorts long before the preamp output will distort. If that alone isn't enough reason the claimed 45w of deck power is not enough for the kappas. You have a pretty penny in that thing spring for a second amp to power one of the sets of coax.

 

Thanks for the reply marshallb! So I should leave the set of mmats and the set of kappas on the tm400x4ad and take the second set of kappas and run them on another amp. How would I bypass the headunit for that set? Connect the second amp using high level inputs?

 

The RF amp doesn't need two sets of rcas. Run one set to the RF and one to the second amp. Might have to play with the level matching or possibly use a pac lc1 on the lowers.

Either use the crossover on the amps or the HU but not both.

Not sure why you would bypass the HU?

Personally I'd put the four kappas on the RF and get a VADM2 for the mmats in the lowers.

 

Thanks! Think that sound like a good plan!!

 

How many RMS Watts do the Mmats 601cx's need to sound as they should?

 

That sounds like good advice. The issue you run into when setting up lower speakers is they need to play louder than the fairing speakers in most cases (think batwing fairings as opposed to sharknose where they are farther away). When I first had my setup the lower speakers were in parallel with the rear pods and I could never get things to balance out. When I gave everything their own amp channel I was able to get them to blend well.

I wound up up putting the front channel preamp outputs on one amp driving the four front speakers. I used an RCA level control to adjust the signal going to the fairing speaker channel so I could tone them down if they overpowered the lowers. Once that was adjusted to my liking I could use the fader control on the bars to blend front to back.

Marshall's idea will accomplish this but you could also run the RF amp on the four front speakers and use the micro amp for the rears. That might make adjusting the sound of the four speakers in front of you easier. The RF amp has some good EQ adjustments on it that might make it possible to squeak by without a DSP at this point in your build. You can't really push much bass to the rear pods anyhow so maybe the micro amp would work fine there. If you decided to do that you could get a pair of RCA Y splitters so you could run one set of patch cables straight to the rear input of the RF amp driving the lowers and run an inline RCA level control inline to the input of the front channel going to your fairing speakers. Then you could tone down the volume of the fairing speakers if you needed to. This is similar to how I have mine setup. Once I got the balance I wanted between my fairing and lowers I adjust front to rear on the fly with my thumb fader control.

I don't mean to overcomplicate things for you OP but I tinkered with mine for months before I got it to blend the way I wanted it to, so I thought I'd toss these ideas out there in case any of them helped.

Good luck.

 

Hoyt 1911A1, thanks for the advice!. Thats were my head was headed but was unsure if the Mmats needed more powerthan the RF was pushing, since I was going to add another amp.Trying to figure out an amp that might work in the Merta 95 fairing.......since it has the sony 7000, really didnt leave any room.......installed the RF in the pack.. I might try to add another one in the pack to run the pods and leave the RF pushing the fronts to help balance as you have suggested.....fun stuff
