Whatever floats your boat.

Fiberglass and foam I assume.//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

No, because I thought I needed it.//content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

whats your setup?

maybe you do need it?

 

[fearof85 10+ year member]

It was gonna be two- MA HK4000D's and about 1400 on mids and high but I lost my job and had to sell my 8-15s and one 4000D.

As of right now I'm doing 2-18's on one 4000D with 1400 on my mids still.

yeah, but what batteries, what alternator?

 

[fearof85 10+ year member]

I have 2-RV batteries(255 ah each) and a stock alt, I know, I'm looking at this 200 amp now but funds are limited.

so you have one in the front, one in the rear?

in which case, both batteries will be giving half the power to the amplifiers, meaning, you need thick cable.

I have 90% of my batteries in the rear, the front battery is only 50ah and won't be giving anywhere near the amount of current your front battery needs to.

how clean is the power on those response amps?haven't heard of them.

thats because I'm in Australia..

the circuit boards are the same as the Sundown amps, but apparently aren't assembled the same, so the ReSponse amps aren't as good

I only have one in there now but plan to put the second one when I rebuild for the two 18s. both will be in the back in the back as they are way too huge to fit under the hood of my Saturn.

well then no, you really don't need 4/0ga cable..

is it a positive and negative run?

 

[fearof85 10+ year member]

Right now I have 1/0 for power and my battery grounded in the back, I have 600 watts on 1-15 now and it drops from 14.5 idle to 14.3 at full tilt. So with 3000 rms it should be pretty stable with both batteries in. Still need to do the big 3 but I'm dreading it.

EDIT- It will be 1 run of 4/0 positive and negative when I get another HK4000D.

How does the OP think he can get away with only one run to the back?

It can work. Just may cause more voltage drop as the wire heats.

...why will the wire heat up?

...why will I have more voltage drop?
