    I just puchased two pioneer car stero head units, boasting 200watts, one for my sons 18th birthday and one for my boat. i installed the one in my sons car along with a new set of speakers. the system sounds great! very clean and very loud. Now i'm exited, i jump in my boat with a 600watt marine amp and the new head unit, and four 100watt marine speakers. after hours of work i turn it on and it sucks. there is very little volume and max volume is less than what i had with the old unit. I took a short cut on the amp power wire and ran it to the fuse box.

    could this be the problem?

Make sure the amplifier is turning on. Remember ther is three wires that power the amp Battery constant, Ground which in a fiberglass boat run ground to battery not motor, Plus make sure the remote wire is hooked to power, generally it is switched power. But if the amp is not turning on temporarily hook remote and power together to battery and see if the amplifier turs on. Second be sure you have a good set of RCA cables hooking the radio to the amp. And finally check and make sure the gain is turned up on the amplifier.

But radio now no speakers work only tweeters
That sounds more like an issue with the radio ground. Some radios ground through the antenna and finding loose connections can be time consuming. You can add an additional ground from the radio to a chassis ground. Poor connection at the Ground can cause strange issues like you are experiencing.
FYI, high-end stereos utilize an amp, or amps, for lows & mid-range speakers so the ground problem could be at the amp instead.

Kenwood no sound
If you have a separate 'power' or sub-woofer amp, check that it still has power and did not blow a fuse. Is there an internal selection inside the unit for enabling the internal amp vs an external amp? Some will disable the internal amp using a setup setting, and just provide low level output that is expected to be amplified by an external amp. If it 'forgot' you might have to set it to use the internal amp again. Or vice-versa, depending.

My Solara Dsc radio, which has worked well for several years, suddenly began blowingthe 2 amp fuse on the red power line whenever the transmit button was pushed on the mic. Why?
No worries here.
According to Uniden, the 6 amp fast blow fuse is the correct one.
Not entirely sure why there'd be a 2 amp with your old radio, but I suspect the radio is good.

One thing to remember about most radios, the RCA pre amp circuit will still work even if the mosfet power amp inside the radio does not. The best way to know if the amp inside the radio works is to use one matching color pair coming off the radio to wire up a random speaker right to the radio. You can use just about any old random 4 ohm speaker that is laying around to check it. The best solution if the amp inside the radio is blown is to replace the radio or amp the pre amp outputs with a small 4 channel amp. Oh, by the way. What vehicle are you connecting this into? And does the vehicle say Bose, Infinity, or ect sound or Premium sound? These usually denote a factory amplifyer already onboard and requires special connections to get the signal to these amps to then be delivered to the speakers.

Disconnect all the speaker leads and then hook one speaker (a new, known to work speaker) up directly to the radio using a short (6"-12") piece of speaker wire. Does that speaker work then?

Best buy installed radio & speakers bad reception told by installer factory wired wrong true or false can i get new harness & instructions where & price
Best Buy has a pretty good reputation for installing aftermarket radios and they generally use a new harness connected to the old harness to make it work right.

I would try to have the reception issue fixed by Best Buy before the warranty runs out.

How long ago did you have it worked on?

I'm sure they will make it right if you take it back.

Even, if it requires changing out the radio.

Have them check that the antenna is properly connected to the back of the radio.

If a boat is anything like a car, the amp's negative post should not be connected to the battery, but to the ground of the boat. In a car, the entire chassis is grounded to the negative terminal, so when you run a line from the positive terminal of the battery to the positive post on the amp, and a line from the negative post on the amp to the chassis it is a complete circuit. I highly recommend placing a fuse on the positive line from the battery to the amp. Wiring this way prevents the amp from blowing up your battery, as well as prevents the battery from blowing your amp. Hope it works.
