I took my car in to upgrade the power wires from 8 gauge to 4 gauge to power my 2 highend amplifiers. Supposely, the correct way to wire the amps is to run separate power wire to each amps. Instead, they wired a 4 gauge wire to a fuse splitter and from the splitter wired 8 gauge wire to my other 2 amps. My subwoofer sound much worst than before due to lack of current. I told them it is not the correct way to wire the 2 amplifier like this. Not only that they put the fuse near the amp (which is a total NO NO!). The fuse should be near the battery, not the amp. I was so disappointed I told them just give me a 15 foot 4 gauge power wire and I will wired it myself. Not only did they took my money for the initial installation, they want me to pay for the 15 foot power. I was so angry I walk out and promise never to return to this unknowledable, unprofessional place again.\r
PS - I went to Frys and bought Monster Cable 4 Gauge power wire and did it myself. Now my subwoofer sound so much better.
Cons: Not knowledgeable on amplifiers hookup
