Works very well with my Rockford Fosgate sub system in my car.

Usable

The following review is for BAK42BK, which is a part of the bundle you are viewing.

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

price is right

The following review is for BAK42BK, which is a part of the bundle you are viewing.

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

awesome products

The following review is for BAK42BK, which is a part of the bundle you are viewing.

I run 2 12inch audiobahn exursions on this amp and it pushes them very well. The size is perfect not to big and fits right unerneath the seat or small space. The best part is it stays pretty cool even after running most the day.

Poor quality

The following review is for BBIC5, which is a part of the bundle you are viewing.

I had ordered a Kicker pk8 amplifier wiring kit and these were part of a package that only Sonic had offered. To put it shortly, one of the jacks was grounding out when I plugged it all the way in the RCA jacks in the headunit. It was causing a lot of doubts in the equipment in my system, but I got down to the root and these were the culprit. I contacted Sonic and they gladly replaced the with a set of StreetWire RCA's that worked just fine when I installed them. Thanks Sonic! But as far as these go, I wouldn't recommend them. Spend a little more and get some better ones.

Looking for bass?

The following review is for THUNDER65, which is a part of the bundle you are viewing.

Okay, first off....I don't have this model, I have the previous model - MTX Audio TDX65 Thunderdomes. Same specifications. I completely upgraded the sound system in my 2013 Hyndai Veloster and have a pair in the back. I changed out the speakers first, left the stock stereo in for several weeks. I wasn't all too impressed at first. Certainly, the sound was improved with way better speakers but nothing to get all misty about. After I finally changed out the head unit.....OMIGOD! These really do have a nice, low end sound. Very deep for their size. They're not super, subwoofer level, but I haven't installed the amp and sub yet and I'm almost happy enough without them. Some songs have such a nice low punch to them that I'm so impressed with these speakers. The only negative that I'm finding is with the sensitivity rating. These have a nice high rating, which is good to have. But I don't feel they're as powerful as my front speakers with the same sensitivity rating.When I'm adjusting the fader, I have to stay on the rear side of center to get good bass mixed with the front. Once I hit center, I barely hear these. I'm considering adding a smaller amp to power these speakers so I can set the level a bit higher than the fronts.
For the price and the specs, these are a really nice set of speakers for bass

The following review is for BAK42BK, which is a part of the bundle you are viewing.

The eyelet connectors are flimsy and the speaker wire is hard to separate. When it does it exposes some of the copper. Otherwise the kit is ok.

Ok value

The following review is for BAK42BK, which is a part of the bundle you are viewing.

Good product , but not enough speaker wire to wire two front door speakers in a scion xb. I guess it would have been enough if I had run one of them with the power wire instead of running on the other side of car, but everybody knows that's a bad idea due to engine noise. You would think they would take that into consideration. Also not a big fan of the square and round speaker wire very hard to separate and strip without exposing bare wire.

The following review is for BAK42BK, which is a part of the bundle you are viewing.

Bought this kit for my 650 watt rms amp. Not true awg 4 guage, but close.jacket is pretty thick.all wires flexible. Reached under the back seat of my 2008 silverado crew cab. But not a whole lot of slack if your going to a trunk. Fuse is ok... ive seen better and worse. Bottom line, if your on a budget and running 800 rms or under, this will work fine.

The following review is for THUNDER693, which is a part of the bundle you are viewing.

Bought the Mtx speakers , wrong size , My fault didn't look up the size , however not a problem because Sonic accept it back and give me a store credit to get the correct ones. Great sound and great service.
P.S. Got send pair for the rear doors - 2006 F250 SuperDuty diesel.

Great wires!!

The following review is for BAK42BK, which is a part of the bundle you are viewing.

After reading reviews and most importantly watching the video Sonic posted with this product, I decided to give it a shot for my Cerwin Vega VPAS-12. The wires are exactly as described, true 4 gauge, not all insulation like the other brands. The fuse block is solid and easy to set up. I was worried it may not fit the VPAS connectors since they mention 8 gauge, but it works and it is holding in no problem.

The only thing I did change was the actual battery and ground terminals, they seemed weak, so i chose something stronger and all is well.

Thanks again Sonic!!

Everything I Needed

The following review is for BAK42BK, which is a part of the bundle you are viewing.

Used this kit to run an amp to the trunk of a 2015 Kia Optima. Ended up trimming about 1½ft of excess to help clean up the install. Everything seems to be good quality. Ran the power wire down the driver's side and RCA & amp signal wire down the passenger side to avoid any interference. Plenty of length of everything for a full size sedan.
