What did you do to your NNBS GMT900 Tahoe/Yukon Today?

The problem with tapping into the speaker wires with a LOC is that a lot of the bass has already been filtered out by the Bose amp to go to the factory Bose sub. If the LOC can handle the wattage, tapping into the signal to the Bose sub may produce satisfactory results. The problems there are (1) it's a DVC sub and (2) it's a small sub so it's crossover has been programmed accordingly and this may leave some to be desired with a larger sub system.

I've found pictures and wiring diagrams before, but you can tap into the low-level, full-range signal going to the Bose amp with some RCAs (cut the RCAs and solder them in) and run RCAs to your sub amp as normal.

lol, beat me to it

this the problem I ran into with the Silverado and using the stock system then feeding the bass signal to a amp and subs, I had to use the stock amp bass output into a hi/lo adapter and it works but it's not the ideal method. the input into the stock (most amp) is a single wire likely some form of spdif/digital signal.

I’ve heard people gain 5-10hp

I wonder if black paint will get me the same results!!

I bet you’ll get 7-14hp!

Goin through something, took a quick trip to Canada to blow off some steam:

It hasn't blown up yet!

Love the 6k shift.

Or you can tap the amp inlets instead of the out. Pre digital processing. Then no worries about lost signal.

Right. That's what I was saying by "...you can tap into the low-level, full-range signal going to the Bose amp..."

Also you should read how the lc2i works. I used it in two cars one with Bose and one without with factory radios with excellent results.

I'm familiar with the LC2i. With how much it can take on the input side, it's a great way to bridge that connection. If I weren't so thrifty, I'd spend the $100. But, it's just as easy, even with my laziness, for me to cut a $5 pair of quality RCA cables from Amazon and solder the female ends to the wiring in the console.

Checked on the caliper paint job I did last night and they turned out great! Used VHT Self Etching primer, VHT Red Caliper Paint, and VHT Gloss.

Goodness your exhaust sounds good!

Thank ya!
It's kustom, yo.

I don't recall if I had the cutout completely open or if it was ~60%. When closed and going through the mufflers, it rattles and buzzes- something internal came loose during that trip to Florida. So I open it just a hair to a point where it stops the rattling but isn't full retard with the noise.

Love the 6k shift.

The tuner was surprised and worked up to that. He started around the factory shift point but saw and felt that it was still pulling well enough to let 'er wind out some more. After I told him I geeked out on the push rod length and size, lifter preload, wipe pattern and had Z06 ("yellow") springs, he's like "Okay, 6,000 it is".

Does that loooooooong and slow WOT RPM climb after 100MPH give y'all anxiety, too?

shouldn't be long and slow until after 120 at least

Eh. Little ol' 5.3, small cam and crippling 4L60...

Although, after watching it some more, I guess it does seem to still be climbing half-decently well up to around 117. Maybe I'm expecting a little too much from the brick.

I determined the "wall" to be around 125-130ish. I let off when it looked like the RPM climb stalled around 5,600.



Running the math just for fun:

5,600 RPM engine speed
1:1 Third gear trans ratio
3.73 Diff gear ratio
32" Tire (16" radius)

= 142.9 MPH

I know I wasn't going over the low 130s. Hard numbers don't account for slip in the unlocked torque converter.

Don't forget speedo error at that speed and coefficient of drag

Have you still got pictures/diagrams of those handy? This seems like the lowest and easiest solution

I like red calipers!

For the vette, i also painted the rotor hats with silver caliper paint to keep them from turning orange...

Did the paint job while i had the pistons removed for a good cleaning and seals.


Been thinking the hoe needs red calipers for some time now.

 

[Danny3737]

synthetic blinker fluid and a new canooder valve with get you another 5 to 10 hp

Took apart the calipers and painted them red tonight (I’ve heard people gain 5-10hp, so thought I’d try. )

I was expecting the Flux Capacitor to kick in when it hit 88 MPH. 6K RPM’s....oh my

Yes it does! Sounds like Dale Earnhardt too!!! And he is going to wind up like 'ol Dale if he keeps this shit up!!

Me wants to see too. I got that aftermarket subwoofer itch again.
