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.

GOOD CAP

The following review is for CAP18, which is a part of the bundle you are viewing.

great amp, your car will perform as if you don,t even have a 1000rms amp hooked up. That's what i have, i say its worth the money.

Ok. not the best kit.

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.

You get what you pay for....

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.

Nice Capacitor

The following review is for CAP18, which is a part of the bundle you are viewing.

No more dimming lights and rev problems with the engine. When the bass hits the engine would drop some RPM's while idling, but not anymore. Voltage goes to 13.5 and 13.1 when the bass hits. I have a 420w rms mono block along with a 70w x 4 rms amp. Not much, but enough to dim my lights and get the juice my engine needs. Installation was a breeze. Charging the capacitor was a pain. After 1 minute the resistor started smoking, and had to stop for couple seconds to let it cool. And after 10 minutes the cap was still at 8 volts (Using a multimeter). Would recommend getting a better quality, lower resistance resistor to avoid losing half your day charging it.
Overall: Perfect, works as intended

Was surprised with the quality of the copper and actual size of the wires compared to other cheap brands like Schoshe. Worth every penny.

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!!

For the price, this installation kit is great. You can spend 4 times the amount for killer connections but if budget and functionality are key, this is the best.

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.

After 5 years

The following review is for CAP18, which is a part of the bundle you are viewing.

Has been working great, but after 5 yrars it stopped working. Disconnected from my car to diagnose just to hear a rattle inside, so, as any engineer would do, I oppened it up. It uses 2 big unmarked capacitors as usual and an array of smaller 2.7V 25f capacitors. 3 of the 25f caps are bulged and the 4 one was missing, rattling inside the casing. It basically just blew up off the board leaving the corroded pins still soldered to the board. I will still attempt to buy good quality Rubicon caps and fix it. Wish me luck

The following review is for CAP18, which is a part of the bundle you are viewing.

I've purchased 3 amps. 1-4000 watt, 1-4 channel 2400 watt, 1- 2 channel 1000 watt. They where dimming my trucks head lights. I installed a 2 farid cap, it didn't help. So I order a Boss 18 farid cap. And I have all the juice I need and more. My amps all hit harder than ever before. Thank you for helping me with a great sound system in my little S10.

Boss CAP18 works better than expected

The following review is for CAP18, which is a part of the bundle you are viewing.

I was very skeptical about this item but it actually works, it helps with the dimming of the lights. im running a Hifonics Brutus BRX2416.1D with 2 kickers l7 subs and crunch 1500watt amp. so far im happy with the purchase but it think that I should had bought the 30farad to complete solve the dimming lights issue
