I decided Bass engine's not made for someone with a decent system.. like who wants a boost at 70-80hz? Also, the first step is already +10db! like woah. If it was easier to get to the Sub output, I might have kept it.
Wish i knew this beforehand. I had the volume low and bass set to factory settings. Pressed bass engine by accident and it instantly blew both my 300$ jbl 6x9’s :( wish the manual had a clear warning about this
Maybe you would know what’s up. I have the 172bt version of this, with 4 volt 6 channel preamp. I’m not getting a real great reading. On my 4 channel RCA’s I’m not even getting 1.5 volts, and with the sub output I’m only getting maybe 2.3 volts. In order to get close to 4 volts, I have to have the BT level cranked to +6, the bass +3 and the mid setting +3 and volume maxed to 35. In no way it should be like this. I have to crank my gains on the amps to unsafe levels.
@@kewlbug Bluetooth , but when I max out the level from 0-6 I get closer to the 4 v but crazy distortion at 28 volume. Bass is lacking. Now the gain on the amp is under 1/4 and clipping on anything higher. I had it setup with 3/4 gain on amp before which is about where I want it for box rise. I usually use Spotify but I’m getting a usb. Normalization had been fixed prior
@@kewlbug well the excelon 807s I think it is, has 4 v preamps. I can only get 2.3 at full 40 clicks, with sub level at max 10. Input source offset doesn’t change numbers at all. This is also with a flat eq. I set gains at 32 out of 40 and I still have some wiggle room. I did not go up to clip light, I matched gains with a multimeter. Now I understand to set the eq first, and then gains. Which way is right? It sounds phenomenal, but if I did not do everything to a T then that means there is room for overall improvement.
So, what is Width, Center frequency, Narrow etc. On the 3 eq? I was playing around with the settings on them the other day. Just wasn't sure where to keep them
I'm not sure how to explain it fully, but once you see you will get it. If you see my measurements from the bass engine, the boost has a center freq around 80hz, it then shifts to 60hz at the higher levels. i.imgur.com/Skg1F22.png The high boost is like 10khz center. The width is just that, a wider area affected, or more narrow. Search parametric EQ, and DSP setup, you might see what the eq bands do. Personally, I wouldn't touch them without seeing what the car looks like with REW and a Calibrated microphone. Or I would fully tune the car with a DSP and only use that 3 band eq for personal taste.
Unfortunately no. I'm still using the 149bt here. I don't want a big stupid touch screen. either 149 bluetooth/CD/USB or I have a Fiio K3 to run Digital straight from my iphone to Helix DSP.
Yes I had one in another vehicle years back Now I have another older vehicle and would like CDE-175bt . I just want a single CD and Bluetooth. Alpine makes nice equipment
@joseph puchel I'm in the same situation. Recently alpine and all other haven't been making any good single din. I have a cde148bt, cda9886, and prs80. But I'm looking for a 149bt...lol
Great video! I have this head unit. I think it’s a great sounding piece. I NEVER use the bass engine.

I dont use bass engine or bass i leave it on flat and set everything on my crossover or amp

Waiting for more test 👌👌👌

What is your source? USB, Spotify? what tracks are you playing? I ask because Spotify, amazon, etc have volume normalization that knocks it down

@@kewlbug I just said forget the hu and went with a kenwood excelon double din and am not looking back. Lol
@@BEAZY_5150 made the jump. lol. will be interesting to see if you have similar issues. Wifes car just got the T'Eyes 9".. yeah that's not for me

I've been looking for one comparable to the older cde hd149bt... any of these newer alpine comes close to it?
Unfortunately no. I'm still using the 149bt here. I don't want a big stupid touch screen. either 149 bluetooth/CD/USB or I have a Fiio K3 to run Digital straight from my iphone to Helix DSP.
Hey I like this model. I need a single CD player and nothing comes close to this.
@joseph puchel you referring to the cde 175bt?
Yes I had one in another vehicle years back Now I have another older vehicle and would like CDE-175bt . I just want a single CD and Bluetooth. Alpine makes nice equipment

Does bass engine have the same effect on the CDE 172?
I bet it’s the same. Since they’re all from the same line
This has a 9 band eq or not
I heard you might be able to with the app. But as is, it’s just 3 bands
Boring 😴 putting me to sleep, great to watch for a good night sleep, outdated scope and old SMD tester 😅
Waiting for more test 👌👌👌
