Customer Ratings & Reviews

Pretty good

It's good for its price. Had it powering a set of Hifonics ZXi6.5s on the doors. They sounded great but I came across a RF punch 400.2 and it now the components sound way better. I'd say this amp does from 60-80 rms a channel instead of the 100 RMS. But I will be using this amp for my tweeters!

Can't rate on durability since I used it for about a month.

Hifonics

I was able to tune it to my EQ, very easy set up...one down fall...goes into protection after a while on hot summer days

Best amp for the money

This is the best amp for your mid's and high's for the money. I have owned it for 6 months and I would recommend it to any one if you are a beginner or like me have thousands invested in your system you would not be disappointed. The other neat trick about this amp is that if you get eight 4 ohm speakers you can actually increase the 400watts output to 800 watts pushing all eight speakers with no problem and trust me you won’t need more power than that. This is the best little amp for your money.

Not bad for the price ...

Recently purchased this amplifier and to be honest I don't think the RMS values are accurate at all ,... like a recent comment I read, I agree that the values are stretched a bit ... I put these numbers to the test and this amplifier did not hold up at all but for the price it does its job, just don't expect 400 R.M.S. out of this amplifier bridged

great amp!

I purchased this amp to replace a 780 watt 2 channel pioneer amp. I have it hooked up to a pair of Alpine components in the front and SPL components in the rear. ( also purchased from SONIC) And I can not be happier. There is plenty of power and clarity. The Amp puts out a great deal of power and do not distort. Great amp for the price no complaints on it. I have been beating the heck out of it for several months now and it does not sweat.

Very nice.

Well only having this installed for 2 days so far, I must say im pretty impressed. I have it in 4 channel mode powering 2 sets of the T1652-s of the R. Fosgate components. Easy install and setup. Pretty cool here on the East Coast atm but this amp can and does get really hot. I love the amp it works exactly how I want and need it too. Overall I would recommend this amp for a fairly cheap 4 channel. So 2 things that I have small issues with is the amp getting hot and at top volume for long periods of time the amp will lower its output due to being hot. And yes I have it in a well vented spot in my trunk.

Great Amp

Has lots of power and sounds great.

Good Amp

Great amp although it does get warm, puts out close to what it says.

HFi100.4

I purchased this amp to power a pair of planet audio bb690's and a pair of Alpine spe-5000 and they sound as clear a a bell.

worth the money

Good amp. Clear highs. Have had it for 1 year no problems.

Great Quality

This is a really a nice set of RCA wires, one of the nicest sets i have ever bought, i would reccommened, thank you Sonic.

Good for the Price

For the price, the cable as no serious flaws. This is a cheap cable for a cheap price. It has better construction than other run of the mill cables and not as good as big names like Monster. The purpose of a cable is to deliver the music signal cleanly to the amp without noise from the vehicle, it does that. However, I had to pinch in the ground lugs to maintain a tight connection, no big deal but like I said not the quality of a Monster cable OR the price of a Monster cable.

Name says it all

True to gauge size, same wire as Kicker. Very easy to work with! Never had a bad product from Tsunami. THANK YOU SONIC! KEEPIN THE PRICES DOWN FOR THE FINANCIALLY CHALLENGED!YOU GUYS ROCK!

cheap amp kit

Good amp kit. Lead wire was long enuff to reach into my trunk. Wire was more than flexible enuff to get it thru the tight spots. All in all for the money it was the best bet. Thanks

Pretty good

This kit has everything you need but the wire quality isnt the best but it still gets the job done

Love it!

I love this amp. It sounds great in my truck. I was looking for an that wouldn't over heat in a small space, and this amp has given me exactly what I needed.

High's on a budget

Works great, i have not had any issue's with this amp at all, this was more than enough power to run all my MB Quart high's that I also purchaced here at Sonic. Thank you Sonic. I would reccommened.

Awesome Amp

This is my second Hifonics amp that I have put in my boat. The first one lasted over 7 years in marine conditions. I am sold on them. Great product

Superior wireset!

This is ACTUAL 4awg wire! Very flexable and durable... I was kind of disapointed that I had to get my own RCA's but I found a great set for a great price!

Good kit for the money

The kit was as expected for a very reasonable price. I would prefer an ANL type fuse holder.

tsunami

this was exactly what i needed!! great product i would recomend it to anybody who just needs a few things out of amp kit and not want to pay full price for one!!!!

Everything you need minus RCA's

Good quality wire and easy to install. Just keep in my mind this does not include RCA cables.

GREAT FOR RUNNING MIDS

Connected this to my mids. 2 6.5s and 2 6x9s. Would recommend to anybody looking to really boost their vocals!!

hifonics hfi1004

Works great, powerful great amp. The sound is clean and crisp. I would suggest running a very heavy power cable. Also have a good battery and terminals and fuses. This is a power hungry amp. Do not go cheap on any of the things I mentioned. You are supposed to use a 0 gage cable even if the cost is high you want it for a reason.

meh

I got this amp to replace my cadence txa 300.4 amp which put out 300 RMS on each side bridged. I was happy with it but after it died I decided to go with another amp. Its okay. Build quality isn't quite as good as the cadence by far but it does look nice from afar. After hooking it up to my Rockford Fosgate t162s components bridged in mono I am left feeling like their claims of 400rms x2 at 4 ohms is a bit stretched. Other than that its a decent amp. You get what you pay for i suppose!

Im only gonna buy this wire from now on.

I love this wire. It just makes your system look clean. Its true 4 gauge. Very true. Impossiable to say that it isnt true 4 gauge. I dont come with everything that amp kit usally comes with, but i already knew that. If u need things like firewall rubber, and rca wires, this isnt the kiit for you. But if u have a battery in the trunk and already have some rca wires, this is the kit for you. I highly recomend it and will be buyig wires from them for a long time. 5 stars.

not bad but not as complete as it should be

The quality of components in this kit are good. But there are things missing that are normally included in other kits like grommets for passing wire through the firewall.

nice

it works well i like it

quality

i replaced my cheapo rcas with this for my 4 channel eclipse amp. have the front 2 channels running a pioneer component set and the rear 2 channels bridged running a pioneer champion series pro 12. i listened to my system befor i hooked these RCA's up and after. i can def say i noticed a huge diffrence in sound quality. even better imaging from my component set. these are very well worth the bucks sonic is asking. for being a cheaper pair of RCA's i love them. and ill keep on using them too! stop reading and buy them!!

Great wires

This is great wiring kit, supported my 1000 watt RMS Crescendo audio 4 channel with no problem. The wires are very flexible.

Great wires! No RCA's though...

Great wiring kit for the buck but spend the extra $$ and get a wiring kit with good RCA wires or your gonna run into some turbulence installing your speaker. Perfect length wires though and even had extra for my 1998 Nissan 200sx.

Zip ties that came with it weren't very good. They were very brittle and almost every one broke trying to tighten them, but don't let the zip ties hold you back on this deal, they're cheap at the store.

Gotta get this wire

This is TRUE 4 gauge wire. All Tsunami wires are True gauge wire. And not only does it work great, it looks great too! From now on, i only use Tsunami wires.

great buy

This is a great product. Cables are high quality and true to gauge size.

You can't beat the price...

Very nice quality

These RCA's are BEEFY. They look great and save you the trouble of running an extra set if your connecting a 4 channel amp. Very nice design and very clean looking. I would definitely use these again.

Great Buy!

This kit has it all and the quality of the wiring is pretty good, not the best buy for the price its well worth it!

Basic wiring kit

All you need for a really low price. If you got a little more to spend I would recommend kicker wiring as well.

great product and awesome price

Great product and awesome deal fast shipping!!!!!!!

Nice Value

Nice kit actually has everything that you will need to get the job done and get the job done right, and the price is right. Thank you Sonic.

Good Value

They look a lot better than the cheaper brands and it seems to work fine with me no problems with them. They seem to be a well made product not like the cheap 1s.

Very convenient and great quality!

The Tsunami brand RCA's are a great value for the quality you get and having a 4 channel RCA in a single length of cable makes install easier, cleaner and less likely to be interfered with. I've now used them in two different installs and will again. I've used much more expensive RCA's before, but haven't found any that are this good at this price.

Everything I needed for a good looking install

Good product. Plenty of material. Easy to use. No complaints.

Good 4 ch. wire

Bought this for long runs to amp from HU. Got quality and good connectors. Didn't get any alternator whine or cross talk. It worked real well for 4 ch. amp install.

A good setup for a 4 channel amp

I used this for my 4 channel amp, and I don't regret it. Easy to run the cable around in the car, the connectors have a nice sturdy feel to them, and it looks nice without being to "blingy". Sounds good, no noise.

nice interconnect

The bundle of all four cables made routing a breeze to my 4ch amp. The jacket had a nice tacky feel, easy to manipulate. Sounds as great as any TWP interconnect.
