Got those same cheepass wire stripers , that’s funny had them for like 10yrs now and they still kickass. One of the best cheep tools I own.

Corrosion over time , check and clean all connections.

You should be able to handle up to 150amps on 4 gauge but I’d limit it to 120amps , if it cannot handle that you need 1-0gauge

Start with an 80 you running amp at 2ohms or 1 ohm

Xtr can handle 120 on 4gauge but I’m scared to say something with you saying your running a 40amp fuse with out me looking at it. If your fuse is to big for your wire ,the wire melts before the fuse witch means your car burns down.

U have a 40amp fuse on your 4gauge power wire to your amp ? What amp XTR or CB

I think that’s a lot for those subs be careful, I ran 3 SA-10’s sealed and to compensate for ported put 1k per sud and they loved it. 1500 watts per sub is a lot if it’s clean and not clipping and loosing a lot of voltage it might be ok but if it gets smelly turn your gain down a bit.

I run that same amp on 2 Sundown SD-3 10’s and it’s a perfect combo. Great video I new it did over rated but not that much.

They don’t recommend sealed that’s why U can’t find anything, the only 8’s I see by Sundown that are for sealed are the E or SD series but if U look at the 10’s U have more options.

Rockford Punch 45 on subs and I think a Rockford 35x4 on mids, both great amps . Mid to late 90’s

That’s a good body shop, I’ve been working on cars for over 25yrs and seen a lot more bad then good.

I was so impressed with the SA line that it made me a Sundown fan for life. Great quality for what they call a starter sub.

Sundown also said if running sealed run more power to subs so 1k each would be perfect butt make sure your electrical is good.

I did use polyfill, I called Sundown and each sub had its own chamber so like 3 separate boxes , that’s what they recommended. Built to Sundown spec. I’ve heard the V3 SA’s don’t like sealed but I could be wrong.

Pics of my sealed and ported boxes.

Sealed boxes are very Punchy but never had an issue with lows , I would just try sealed and if you don’t like it build a new box but I’m pretty sure if you have sealed now you’ll be fine with these subs sealed. I went with 3 10’s sealed to compensate for 2 ported 10’s. I also built a ported box for 2 10’s and it was very close to the same sound as the sealed but not as punchy though. I really liked the sealed sound. If U have room for ported I would go that route.

Ran 3 SA-10’s sealed for 3yrs on 3k and shit pounded. I was very happy with the subs would do it again any time.

Both subs bottoming out or just one?

It’s a box issue can we see pics of the box.

I’m hoping 10 -15 watts but I’m guessing it’s gonna be more.
