RD 7500.1 running 2 12 inch Ascendant Audio Mayhems (might go up for sale)

So yeah. This will be a slow build. Because I wanna pull the motor first and look some stuff over.

But I encountered the first problem that I figured was going to happen. Once I got my front end off and out of the the way. I grabbed the 2nd alternator that I haven't put in the car. I set it where it is going to go...and my stupid front sub-frame gets in the way. The alternator bolts up. but...I'd like some more room. As the alternator literally touches the sub frame. So I will have to get that solved.

But this will be a slow build. I have all summer to get it done. So don't hold your breath.

Rust will be my greatest enemy in this project.

I will put up pics of everything as they roll along. I already have everything. Just debating now on whether running my mayhems on the RD7500.1 @ .7 ohms or switching to subs that are built for that kind of power.

















 
I got a good jump on the whole thing. All the interior is out and dash is apart.

But I ran out of speaker wire. I ordered a 50ft roll when I should have ordered a 100ft. And I needed another 2 channel RCA for the 6 channel amp.

Could be a lot farther if my brother would help me get the engine out. It's on the hoist and suspended. But I need his help with getting it out.

 
Ok. So. Used 4 cans total of engine De-greaser on my engine bay and engine. Got a lot of it really really clean.

Going to spray some truck bed coating along the engine bay over some of the rust.

And then I have a surprise that I am going to be doing.

Right now. I am waiting on funds $$$. So broke after buying all these parts. And I need to buy some more. So until then. I will keep making progress on other things. But I do really want to get the engine back in.

Nice, man. Sounds like a fun build.

2nd time I have pulled a motor. First time that I remember doing it and on my own (with the help of a friend). Once all cleaned up and engine goes back in. I will start working on the 2nd alternator install.

How's it going Adam? Doing well I hope!

Thanks for the post. LOL. No love yet on this build.

 
We want to see more pix, this sounds like a solid build.
Uploading pics right now. I didn't before because I figured no one would give to shirts.

F.Y.I. Check the begging of the thread for a before and after of my engine bay.

And I am still going to do more. I hopefully do it this weekend. For now I just gave it a coating of bed liner.
