Best Buy!
The cleanest and safest way to run your power cable through the firewall. This is a must for any car stereo build.

Really Nice wires
The wires are well made with heavy insulation and bend easily to fit in the tight areas of my truck. I would buy these again for my next truck.

Does what its supposed to
Kinda expensive for what it is. Your really paying for the street wires name. Its does the job and works but i may try a cheaper option next time as they are really the same thing..

Works Great!!!
I used these for my power wire from the battery, through the firewall to the amp. So far, I've not had any water come through the hole, which was a problem before I used these.

Works!
They install securely and keep the water out!
Make sure you have a small and easily-coerced flexible person on hand to hold the nut in place when installing in a blind location. It cost me a grilled cheese sandwich, but it was worth it!

better than rubber bushings
honestly guys if your not using power wire firewall bushings your risking wire damage or even worse system and vehicle damage. these are super easy to install and even make pulling your wire easier! MUST BUY FOR ANY PERSON WHO WANTS THE JOB DONE RIGHT! I will never run wire without these again...
