In recently had my boom box 6.5 flashed at a not so local (40 miles away) RF authorized dealer. I had it flashed for a 2 amp/ 6 channel setup as it sounded a bit louder than the 1 amp/ 4 channel flash and I am thinking of adding lowers anyway. Prior to that, my HU was HD flashed for 0 amp/ 4 channel ( like an ultra) so I could have fade control. I also had the bt 355 LL in play. A lot of different speakers are used but the amp is a tm400x4ad.

After the flash, the setup was louder and SQ was good. Rca cables are gone, bt line levelers are gone and just direct wiring from HU to amp. What I have found is that flash is so flat that the "punch" or lower frequency pound is gone. I still have all the lower frequencies but there is no thump any 6x9's in the lids. I think that flash to flatten out the eq curve is just too flat. The setup with the bt 355's sounded better as after adjusting the LL's (both filter and gains), sounded a ton better. I have adjusted the LL's on a few different installs and I will tell you that if you leave them as BT has them set as default, you leave ALOT on the table with just about any set up. If I had adjusted the LL's when I had a focal sport amp, I probably would have kept it and still would be running it today.

I had Gann listen to it and he also said something was missing. He questioned me as to why I had the flash done as my setup sounded good before the flash. My thoughts were/are the LL and using hp filters on the amp filters the original signal twice and some SQ has to be lost. Besides, I just wondered if the indy flash would generate better SQ by not using the LL;s. I know I'm not the only one wondering that.

So now that I had the indy flash done and SQ just isn't to my liking, I could take it back and have the original flash put back in it for an additional cost or? I did some research on the flash tool. Most RF dealers use the techno research centurion diagnostic tool for these flashes. I considered just buying one but regaining the cost of $1400 or spending that much for personal use just doesn't appeal to me.

With that being said, I would suggest using the LL and adjusting them vs. the indy flash to flatten out the boom eq. In my opinion, the stock flash or 0 amp/4 channel flash (for fade control) and adjusting the LL will provide a better SQ than the indy flash.

The other solution is aftermarket. I just installed a sony xav 5000 HU and now I have the SQ I have been looking for. Adapting aftermarket equipment to a boom HU can be a huge challenge to get the SQ all are looking for. Although the boom is a ton better than pre rushmore harmon kardon HU's the boom is also manufactured by harmon kardon and aftermarket just has a better SQ over all. I contribute that hu is partly why fmfpj's setup sounds so damn good and those vo 6x9's sound like huge subs in the bags. That setup just sounds damn good. Yoop, Gann and others sound damn good all with aftermarket hu's.

Just my thoughts.

PS. I have my big boy pants on waiting on Tailwinds response as to reason # who knows as to why you should use the bt355 LL or any other bashing he will give me on this post.

 

 

No fade control with the 6/2 or 8/2 flash. Will be experimenting with the 8/2 flash this weekend.

 

Yes sir. Never lost that from the original flash.

 

Im curious what tool was used to flash that setup? I retained fade with my flash.

 

 

Buddy just had the same done at a RF dealer and he lost his fade control with the 8/2.

 

I would like to know too as I had no problem with the fade.

 

That was part of my decision, I knew the Sony would be way easier to sound good. Not to mention, I had the 4.3 Boom and Air cooled not wet head lowers. This was all a plan when I was shopping last year for a bike. Plus the Sony is only a couple hundred more than a DSP.

 

I confirmed through Haze that the 8/2 does indeed lose fade control. I may have misspoke on the 6/2 flash.
