'88 RCLB C3500 "Roscoe P. Coltrane"

[Erik the Awful]

Pretty much finished the truck box + shelf. I have some 3/8" plywood around here somewhere that I'll cut for the shelves. I still need to sand, stain, and varnish it. Maybe next month I'll have the cash to spare for the amp.

I also managed to score a garage sale truck box yesterday for $40. It needs a little rehab, but that's a tomorrow job.

How's that thing sound????

I couldn't tell you the last time I saw an OG waffle grill, that's freakin AWESOME!!! Lol

I got the amp in the day before yesterday, and after I gave up working on my son's Chrysler last night I screwed the amp in place and started running wires. Tonight I'll put it on a jump box and run an RCA adapter from my phone to see how it sounds.

Here's the amp. Build quality seems fairly nice. It has a nice "bass level" knob made of metal with a mini-jack, not the cheapskate plastic with an old-school phone cord you usually see. The proof will be if it bumps.

...and the amp is DOA. It powers up, but doesn't produce any sound. The phone plays fine through the shop stereo's RCA inputs.

Do you have a multimeter that you use to see if any voltage is coming out of the speaker outputs on the amp?

12v into the amp, good ground, remote has 12v, and the amp powers up. The little blue LED says so. The phone and RCA cable produced music through the shop stereo, but plugging the RCAs into the amp doesn't produce sound.

The amp is a monoblock, but it has two sets of speaker outputs. No matter which combination of terminals I check with the meter, I get no voltage on my meter. The speaker has two coils, and I have them wired up in parallel. It's a 4 ohm speaker, (measures 3.8), so it's probably 1.8-2.0 ohms, which should put me right around 600w.

I may play around with it a bit more today.

I would run a rca cable from your actual stereo just to double check the signal it is receiving.

For some reason I never tested the amp with just one of the voice coils hooked up. I was very careful when I built it to make sure the speaker polarity was correct, and while testing this afternoon I unplugged one set of wires while the music was playing. Suddenly I had thump. One of the sub's coils is wired backwards. Doh! It sounds nice and the amp and sub are capable of more bass than I'll need.

After sorting that out, I set the box aside and put the tool box up on the cart. I rolled it out into the wind and primered and painted it black. Pics to follow when I install it.
