Ok thanks. I'll check them out.

Dynamats over priced try stinger expert, second skin or fatmat. I'd also toss the Cap and just make sure you have decent wire. Anything under 1k rms and you should be fine with good 0 gauge and a 0 gauge big 3. Just my opinion though not many people running caps these days.

I really like the second skin damplifier, it's easy to work with (cut and apply) without the huge mess from butyl getting stuck on everything. I wouldn't recommend knukonceptz deadener, it's extremely messy and I got some in my carpet and is very difficult to get out.

I have dynamat on my trunk lid, knukonceptz on the trunk walls and floor and second skin on my doors, roof and rear floor. Second skin is kinda expensive, so if you're on a budget I would suggest getting another brand.

Dynamat isn't bad on ebay. I use ebay for pretty much everything. Got my subwoofer for $141 brand new. Got a 1000 watt rms kenwood amp for $165. A box made with the type r in mind for $67. Dynamat is only like $70.

Rough estimate on what I would need for trunk and front doors?

The first pic in this thread is my front door, I used 6 sq ft. per front door, around 4 sq ft on each rear door and trunk about 30sq ft. In total, for full coverage around 50 sq ft total.

There's 26 in my trunk. Take a look at the Stinger expert it's good for the price dynamats too expensive considering what else is out there that's better imho.

$67 for a box isn't going to net you anything remotely suitable unless you're making it yourself but /shrug. What Kenwood did you get? I wouldn't go too cheap on everything you tend to get what you pay for in car audio.

Here is another option for deadener and it's quite cheap: http://www.b-quiet.com/extreme.html I haven't used it before but from what people tell me, it does the job.

I got the KAC9106D for the amp. Runs 1000 rms and 2000 peak. The type r runs 1000 rms and 3000 peak. Item ID number for the box is 281391052746 on ebay. I use the app so I don't have an exact link. Does it make the product better if I spend more money on it?

Looks really good. Very clean install. Can't imagine 4000w when I think my 1000w system is plenty loud. Is the new alternator gonna be able to handle the extra power draw?

Thanks. 4000rms is going to be loud, and is probably going to be the most I ever put in a car. The alternator is going to help out a lot but I'll still need battery power to help out. I have the xs up front 65aH and an oddysey pc2150 105aH battery for the back, I may need another pc2150 then I should be fine.

I'd like to upgrade my battery and alternator as well. What would you suggest? The plan is to run about 3000 rms between subs and regular speakers.

In terms of alternators, what engine do you have? Mine was made by Singer alternators, I would get the larger amperage one you can find 220A+.

For batteries: XS power, north star, oddysey or deka. Depending on your main battery, you will probably need 150-200 aH rating total. So like 2 extra Group 34 or 31. Deka's g31s are very cheap and do the job.

I have the 3400. It'll probably be more like 2400 rms. I plan on getting another type r sub at some point. The 6x9s and 5 and a quarters are 100 watts rms and 300 peak each. Nothing too crazy, but should sound pretty nice.

Picked up these Toolmaker Metalworkz battery terminals from the US on Saturday. They have 6 inputs for 1/0 gauge per terminal.

Those are intense! I was looking at them but i know there's no way I'll ever need that many runs... not to mention how well you put that many runs through the firewall lmao!

It would be difficult to fit any more runs. These terminals are so much better than the Knukonceptz terminals. Mainly because they actually stay connected to the battery.

The others were just a clamp style that kept coming loose right? I'm noticing that with mine and they won't even tighten to the kinetik battery terminals....

Exactly. I would tighten it as much as possible, and it was still loose. The terminal actually fell off once when I was driving.

Went ahead and got the 2 Tantric MD 12's and a SQ Q1-2200D..now just gotta bank another 500 or so for a Singer :<(... Never ending money pits. Only a $30 difference between the 270 and the 320 so going big to build in some overhead in case I want to upgrade YET AGAIN!! lol.
