Ok brother, unfortunately u really cannot run anything in parallel w that ARC amp on a sled. It's again one of these constant power amps that ur gonna get 150w per channel whether ur in 2 or 4 ohm.

Thus, ur gonna need an amp in a bag or pack.
U are prob ok with the 600.4 powering u lowers and fairing but those are power hungry speakers so put some replacements if ur Xmas list for next year.
Regarding the rear, ur gonna want a solid 4 channel amp that will push close to 150 @ 4 ohm and 225-250 at 2 ohm. The Focal Sport is a great little amp and brings the power. U can run ur 2 sets of 6x9s in parallel and the TP speakers off the other channel. Ur budget will drive the amp u select so if it's just one amp tat ur needing u may toss out ur price range and see what folks can suggest.
U not far from getting ur ship to shore brother, it's just unfortunately not gonna happen witty putting an amp in a pack or bag.

Psoff,
I agree with you 100%! However, the moderator for this forum does not.

I've gotten interested in the OPs build as it is similar to mine speaker placement wise.

I had considered the FDP Sport for my rear four speakers but it wouldn't fit on the side of the bag where I wanted to put it and I didn't really need 175 watts going to my pod speakers anyhow. I am powering my 6x9s in the lids and 6.5s in the pods with a TM400x4ad and really like the sound, nice and warm with great adjustability built into the amp. Depending on speaker choice the roughly 120W per channel that this amp puts out may not be enough though for some folks.

In the future if I feel I need more power I thought about bridging the TM400x4ad for the lids and getting some type of waterproof amp to mount under the tour pak for the pod speakers. I think JL makes a few that may fit. I bought an original Harley amp bracket from a CVO off of eBay real cheap in case I ever wanted to go that route.

Has anyone here done an under the tour pak mount before and if so what type of amp did you use?

I realize if space is no object something like the FDP Sport would be a great way to be one and done with it, but I like how little space that RF amp takes up mounted to the front facing side of my clutch side saddlebag.

 

Brother, is the amp u recommended also a constant watt amp?

Sorry T I didn't mean to recommend an amp for the OP I was just tossing out my old idea of a separate amp for the pod speakers mounted under the tour pak to allow a little more customization such as a more powerful two channel amp for the lid speakers.

The TM400x4ad does put out a little more power in two ohms though:
128 Watts x 4 @ 4-Ohm
152 Watts x 4 @ 2-Ohm
290 Watts x 2 @ 4-Ohm Bridged

So I if someone were to use that amp with a two ohm load it could be a contender I guess. I like it fine at four ohms now powering my four rear speakers. I guess it helps that the Polk 6x9s in the lids are complemented by the AD CX62s in the pods. Maybe with four speakers going at once helping each other not as much wattage may be needed pushing each one. If the OP wanted to put all four 6x9s in play though I don't know how they would sound at 76 watts each. He might have to turn the gain down on the four ohm channel going to the 6.5s in the pods to even things out.

If someone is interested in using that TM400x4ad though some of us have found that it likes a higher voltage signal on the inputs that some other amps do. If the OP has an aftermarket head unit it might not be an issue. If the gains seem to need to be turned up real high to get good volume out of it though a cheap PAC LD-10 line driver solved that problem for me before I got a DSP with voltage adjustment on the outputs.

I have four 6.5s on my front stage powered with 140 watts each and the TM400x4ad on my rear speakers and like it, but I don't know what kind of volume or frequency ranges the OP is after. Sitting still everything matches up real well front to back with the fader in the middle. Once I get rolling and the pipes start blasting I run the fader towards the rear about three or four notches and everything balances out again.

 

Thank you, this is the kind of information I was seeking.;

 

That's all I am implying brother. The OP wants to put 6 speakers in play and the TM400 is just not the right ingredient for 6 speakers. Parallel ops puts u at 60-70 watts per speaker and that's just a bad place to be on a sled.

I'm sure it's a good amp for the right applications. Just trying to make sure the OP does not go down the same rabbit holes we have all been down. Constant power amps & parallel operations is that rabbit hole, unless the amp starts with 300 Watters per channel.

Ok, Thanks all. I'm back to square one. I was just trying to find a way to bring the front speaker up and maybe connect the other two speakers I have taken up space in my bags. My winter project went to sh**. I knew I had to get another amp, but I wasn't trying to break the bank.

 

We all understand broken budgets. I guess the question someone might ask you is where are you thinking of mounting a second amp? Maybe with that info some of the smart folks can recommend a particular model for you. If you really want to get six speakers blasting on the rear end you may be getting into the more expensive amps though. If you don't mind losing the extra set of 6x9s you could get into more affordable territory I suspect.

How is the second set of 6x9s mounted in your bags? Do you REALLY want to keep them in play or do you think you would be happy with just the lid 6x9s and your rear pod speakers? If you can clarify that I think someone here could give you a good direction to go in.

 

second set is inside the bags toward the rear. it is not as important as getting the front louder. I figured that being the wattage and how they are wired, i would lighten the load on that one amp and put in a smaller one maybe for the highs and let the Arc take care of the 6x9's. I guess I was waaay off base with my thinking
