My 2 subs weigh 65 lb each and the box is 20 lb so opening it was like weight lifting.
I put the box in empty then mount the subs and do the reverse to take it out.
I got some universal tail gate struts on Amazon that come with mounting brackets
and also got some some hinges and put them in.
Used fender washers on both sides in the well which is quite strong.
Now I still use the post but only have to exert about 10 lbs of force to lift the box open.

Found these CT Amps on Amazon for 179.99
600 watts RMS at 4 ohms comparable to my old Rockfords and the Planet Audio amps I was using.
They are only half the size of the 500a2 ans 600a4 and the P Audio
The Rockfords I've been using for 20 years are getting too old to rebuild.
Something else always keeps going.






Great wire connector terminals







I'm still running my last good 500a2 but ordered another one of there CT amps for rms 600 watts bridged at 4 ohms to try out for the front speakers.

This looks tempting so I decided to get it.




www.amazon.com


Amazon.com: CT Sounds CT-3200-1D Class D Car Audio Monoblock Amplifier, 3200 Watts RMS : Electronics
Buy CT Sounds CT-3200-1D Class D Car Audio Monoblock Amplifier, 3200 Watts RMS: Mono Amplifiers - Amazon.com ✓ FREE DELIVERY possible on eligible purchases

www.amazon.com




I can stack or put the smaller 600 watt rms @ 4 ohm amps side by side and move the Capacitor to the other side.
Also move some + and - terminal boxes.

Easy stuff

and put in this 26x 5.75" 3200 rms mono amp in place of the old school Rockford 1500.1
My speakers will easily handle the power. :love:








26" including tape measure

So the second CT 150.4 got delivered this morning on Labor Day by USPS huh? :cool:
I bridged it for my front 2 Hertz 6x9s.
The other one is 2 channels for the rear 6.5s and 2 channels for the under seat extra subs.
These CT Amps are really Awesome sounding.
So clear.
And they don't get very hot.
Better than the old school Rockfords and so compact only half the size of other brands.
My Mozart Symphonies are a real test of amp/speaker performance and they have never sounded better 😄


.You could put 2 under the passenger seat and a CT Sub amp under the rear seat.
They fit good up and down in my amp bay and the controls are on top and easy to tune in.
I used some right angle RCA connectors.
Have to extend some wires to put the amps side by side to make room for the Cap.
I'll do that later when I put in the CT 3200.





So I ordered 20 ft of 1/0 Blue power cable, 10 connectors, A 300 Amp breaker and a larger 8 Farad Boss Capacitor.

8 farads? Dang son! I always went by 1 farad per 1k watts. I wanna hear that thing
I have a 2 farad Cap right now and don't get any dimming when she's thumping but might as well spend some of my money on my toys :D

Bigger Cap won't hurt.

This is the one I chose.

You’ve got to be an electrical engineer
I'm an Accountant 😄 and CFO
I also have 50k hours of autobody/paint and home renovation experience.
My brother is an electrical engineer and we own a 220k sq ft engineering manufacturing press molding facility with 120 employees on 3 shifts.

My parking lot


My private lift room


One of my first jobs when I was 18 was installing car stereos.

There's a chart.
Pretty straightforward.
Resistance of Amps over distance with DC power.



I have 4 Gauge 200 Amp breaker right now and for the length of 8-10 ft in my case for 300 amps it recommends at least 2 Gauge but 1/0 is better since I have 3 amps.

So my 3200 came in on Tuesday and I have put it in

Made up some 1/0 gauge cables



Have to take the 65 lb each subs out to get the box out to put in the new cable











1/0 gauge wires to the amp.
Negative cables are short so I painted them black



These amps have vents so they have to be mounted to allow for air circulation







Need another terminal connector that's coming tomorrow from Amazon



I'll put the Sub Box back in tomorrow when I get the connectors.

Looking good so far.

Got it back together and decided to locate the in/out fans with the amps as there is just enough room.
I think it's better.
May still redo the fan holes.
Just waiting for the new terminal connectors.
Probably finish it tomorrow.
