Hi there, i have a peugeot 306 with a 800w amp 2X400 and 2 10" subs. When i wire the amp up as usuall i get bass but its a lot of air and not really heard apart from when your heads in the boot. Whilst fiddling around one day i realised that when i touched any of the speaker outputs to the outer casing (with a screwdriver, purley accidental) the bass sounded the B****ks. Then i'd remove the screwdriver it sounded dismal again! Ive chatted to loads of people and its been suggested that its a major grouding issue. So out came the metal file and i removed all the paint around the grouding point. No change? So the next option was to buy some phat 8awg cable and run it straight from the (-) battery terminal to the amp.. STILL NO CHANGE? Any one with any suggestions? Its looking possible that the amp might be faulty. But i got it on the cheap from where i work as it was a discontinued item, so a refund or exchange isn't really my idea.. UNLESS I HAVE TO! |

Running a wire from the negative terminal is only making things worse. the ground cable should be no longer than 18" Are the numbers your listing RMS or peak? running 8 gauge wire to an 800watt amp is a really bad idea. needs to be at least 4 gauge, both the + lead on the amp, and the ground wire. "youre only as strong as your weakest link" as they say... try that out. |

The problem with 4awg is that it doesnt fit in the terminal on the amp. Although it was a strugle getting an 8awg. At the moment the power runs down the middle of the car. The ground goes to a middle seatbelt bolt which is about 15" long. Its just weird that i only get pukka bass when i literally short the amp! any other solutions is it possible that the amp is faulty. One other thing is the head unit has no RCA outputs so what i have done is used a device that changes the wires to RCA outputs. Im litterally about to go and see if a different head unit solves it! |

Well per my last experiment the amp works better with a head unit with RCA outputs. but no CD!!!! :-( I didn't think there was any problem with my wiring. so now all ive got to do is buy a head unit with CD and RCA outputs! Thanks help2 for your help! |
