Tsunami TSBT-PN

This is a great product for the big three upgrade. I had no problems connecting the 0-guage and some stock wires to these terminals. The only down side are the plastic covers, they come off real easy. But they look better with out them. I recommend these terminals for any audio power upgrade.

Makes wiring too easy

xs d3100 battery located in the trunk couldn't of been easier to install with these. Quality built and ditches any thoughts of getting a distribution block.

great price

Great price for something that everyone else is charging an arm and a leg for. Works great, and you get great options with two 1/0 AWG or 4 AWG outputs, and two 8 AWG outputs. Ive had them for over 6 months now and had no issues at all with them.

Great product

Works like a champ and made my sub installs simple. Would purchase again.

First ones stripped, ordered more.

These are some nice blocks, and the only ones I could find with 2-1/0g and 2-8g's. The fit snug on the Yellow Top 34/78's. I tightened the positive block with a bit of force, and stripped out the internal threads, trying to ensure the best connection possible as I'm running 5500+ watts RMS off of two BRE2500.1d's. I would use caution when tightening these terminals, so the same thing doesn't happen to you. Zero gauge fits tight in these terminals, but with a bit of twisting, you can manage to get all of the wire in. Overall, a great buy if your planning on using the top posts for your BIG3, but if your batt has bolt down side posts, I recommend using those instead.

Best Value

These are some solid terminals, very well built. They could easily be sold for twice the price and still be considered a good deal. They have a brushed nickel plating, so you don't have to worry about the finish coming off and getting distorted like the gold ones, which have a very thin plating and have to be replaced after a year or so. Also important is the thread quality, you don't have to worry about these stripping out like other similarly priced terminals. Definately the way to go if you want to do the Big 3 AND run a zero gauge to the back!

Amazing product

They installed less than 5 mins. Great for the big 3 upgrade. Installed on a 05 ram. Lights do not flicker any more.

Oh my wow

Great glad I ordered these before they went out of stock, on my Kinetik 1800 jeez they are worth twice the price, SonicElectronix rules!!! These are great for the big three upgrade, if ur a real basshead :p, buybuybuy!

do exactly what they are supposed to!

feel very sturdy, screws tightened up with out fear of stripping them, and fit the posts perfectly.

Perfect!!

I did the Big 3 upgrade with these and I could not be happier with the results. These are some heavy duty terminals; the best for the this price.

Value For Money!

One of the few better priced battery terminals that offer 2 0awg in for both positive and negative. Good for those that have more than 2 amps and need BIG 3 upgrade.

Just what I needed!

Excellent design. Rugged and easy to install. You need metric allen keys.

Awesome connectors!

Replaced a 5 year old set of Stinger gold connectors with these. Very tight connection and holds the wires really well. A bit bigger than I thought they would be but it's not an issue. Definitely recommend these!

Great Terminals

This set is great, they only fit one way, not universal sized like most. great contact, never had an issue with power from the battery since. Especially great if you have multiple electronics that need power (amps, underbody lighting, etc).

Tsunami TSBT-PN

These are great! had a little trouble fitting my 1/0 but works great, and looks sleak... i have this in a show car monte carlo...

good product

Works great, will recommend for the big 3 upgrade.

awesome buy

I have these on my Kinetik Battery. Awesome connection. And professional looks. These are very very good for the price. Get them! Sonic ftw

Good Value

Does the the same job as the more expensive brands. Save money where u can

good product

I have these on each terminal of my xsd3400 and they fit perfect have all my 0 gauge running into them and I have no problems looks great too when I pop the hood and take the covers off the terminals

Tsunami TSBT-PN

These installed in less than 10 minutes. Great for the big three and also for running 1/0 to the rear for extra batteries, tsunami did a great job on these for the money.

Get the job done

I don't usually buy tsunami products but this product is definitely worth the money.. I'd recommend it to everyone

Good quality

Love the design, but the capacitor mounting hardware could be better. I ended up using Velcro to keep it in place.

worth every penny

I bought a pair of these terminals to replace the old worn out ones on my Integra and I must say I am very impressed. They clamp down with authority once you tighten them they are not moving period! And also they look good while doing the job. A very nice compliment to the engine bay. And installation was a breeze. Took less than 15 minutes to get the old off and on with the new. I would definitely recommend these to anyone lookin to upgrade for looks or performance

Awesome

These things are solid. The fittings could be a little bit bigger to make the 1 gauge fit better but it works.

Awesome

This are great battery terminals. Worth the money buy them.

Perfect

These terminals are durable and conduct electricity well. I have nothing to complain about.

Perfect

Solid
Not Cheap
Fits my 2 AWG wires
Just what i wanted for a reasonable price

Gets the job done

I have had alright success with mine, i have two sets of these and the set in my engine bay corode and i have to clean them. but other than that they work well and can hold 1/0 gauge with ease.

worked pretty good

had to put them at an angle to be able to tighten them and the negative tightening screw is on the wrong side other than that they work perfect and easy to figure out

decent product

Has multiple spots for different size wire eazy fit to most posts and looks good.

Best product out there!

I bought these for the 1/0 outs and these are the best terminals I've ever owned. I have a pair of the stinger's and they are so much harder to use IMO then these by far!

The one con I can find is that one only mounts to a positive post and the other on the negative.

The plastic covers on them make the install look so professional and clean.

perfect terminal upgrade

I have used many battery terminals and none compare to this product. Total terminal protection with durable rubber and plastic. Easy to use as well.

Great Product

This product is awesome!!! The terminals easily accepts 0 gauge and they're very solid.

Awesome!

These terminals are so easy to use and look great. I have been very happy with everything about this purchase. The terminals have a nice solid feel to them. They have a hard plastic cover on top of the metal connector piece that snaps onto the terminals effectively protecting the wires that you are using. Multiple gauge wires can be used in the terminals; all you have to do is take out or put in the metal brushings. These terminals are definitely made to last.

very good product

Installed these on my 1800 kinetik battery in the trunk of my 96 Caprice, these terminals are very heavy duty and work very good,
and you cant beat the price.

awesome

The best terminals I have found they work way better than any others I have used. You also can't beat the price and I have tried. I use them on both batteries in my rock crawler and have never had a prob after many offroad trips.

rca`s

Very nice affordable product easy to install. Nice colors.

Great Deal

I was looking for some decent terminals at a good price, and these fit the bill nicely. I'd definitely buy them again.

these are awesome

Super high quality construction and they look awesome in the engine bay tidying up my wire mess.

Great value

Tsunami top-post terminal are good quality and great price. I've had them for months now and they great if you are looking to prevent any shorts from the battery.

Excellent

I would buy this again, Good buy!

Great Product

Works very well. Clamps onto battery terminals very tightly. Accepts many different guage wires / configurations. I especially like the plastic covers. Not only does it add to the aesthetics, it prevents the terminal from shorting onto other peices of metal. I have a strut tower brace that runs directly over top of the positive battery terminal with about and inch of clearance. I've heard horror stories of cars catching on fire because they did not have this insulated with a strut tower brace. Terminals on my battery were slightly different in size, one is larger than the other to accomodate.

perfect for adding another battery

title says it all. i was adding another battery and this made it extra easy to do

Great value

Great product well worth the money

Tsunami

Good Tsunami Positive and Negative Battery Terminal

Great deal

Worked well, easy to use, looks good. No issues, makes installing easy.

Tsunami? Heavy duty, dude!

Both of these feel like it weighs like over half a pound. Smells like the train tracks too, lol! Tsunami is the bomb!

geat but fatt

this product is great but the clearance is a bit*h great for the BIG three but just get some ring termanls instead

Pretty solid!

These things are pretty great, not cheapy like other ones.
Cons: For my specific car battery, I had to tighten the heck out of it to get it to snugly fit, not a big deal. Also the little metal piece that adapts the 1/0 gauge to 4 gauge feels cheap, at first i thought it was plastic, but i tested it for continuity and sure enough it conducts electricity!

GOOD VALUE FOR $

this termianls are good looking, heavy and well made except that u cant really put in a 0/1 awg cable into it its real hard. terminal covers are good too. overall its a great value!

Tsunami TSBT-PN

These terminals are good looking. I hooked them up to a second battery in my trunk. One of my favorite features is how the terminal is covered by a plastic cover. This is important because you don't want anything making contact. Make sure these are in stock before you buy them or else you'll be waiting forever.

Good product

Works great and looks nice... Only downside that there is nowhere to attach jumper cables in case you need a jump. Other than that it has all of the terminals I need. It has a sleeve that you leave in for 4 gauge use and you take the sleeve out to allow for a 1/0 cable.

Great Product!!!

This is a great product. Bought it to use on the Big 3 upgrade on my car and clean up the wiring mess that the last owner made and it did it perfectly. The fit is perfect and they look great when you open the hood. I will take these over ring terminals any day.

One of the better terminals out there

This terminal has a very nice look with the brushed finish and snap on covers. It has as many terminal connections as I needed. The only thing missing is an easy way to hook up jumpers, say when you need to jumpstart the car. I had to go get some big clamps I could use to clamp onto the body of this terminal so I could hook a battery charger up.

Grest terminals easy to use fit thick wire and look Great

These are great terminals, look very sleek and smooth and feel very quality, they fit my 0g wire quite well and the Allen key screws are good as well, I recommend these for the price - using them on my D34 optima yellow top.

Awesome product

Finished off my custom cable / battery install and left plenty of room for future upgrades and it looks great!

Great

They work great nice and tight o my battery terminals and fit my 0 gauge on my big 3 perfectly

Great and Cheap

These worked great, I used them for a Big Three Upgrade on my civic and they got the job done, with room add factory grounds for backup. Easy to use and didn't cost to much. Highly recommend.

Great product

Works great allows you to connect a lot of cables directly to the battery. For the price it's a great deal highly recommended.

Good Product

I have they on a yellow top OPTIMA BATTERY with big wire on both + and - they look good and hold the big stuff.

As always Sonic had them to me fast at the best price. I look forward to more items from the team.

Deliver the Goods!

Great product, great value, great service. I would recommend this product highly.

Great Product

I highly recommend this product for everyone.

Just as good as the kicker ones I have

So far they seem fine but I cant mount them yet. Im still waiting for the top post to come. They sent the wrong ones and now I wait 2 days for a RMA and 10 to 14 days before they get them to me. But this was the the best deal I could fine. If you need two 0ga in's or out's this would be the one to go with.
Only bad thing is that they don't mark them + or - but I didnt need that.

Works as expected

No issues arrived quickly Help on to the terminals with no problems.
