Default What do you think of this amp?

Working on upgrading my system because it doesn't work. 99% sure it's the amp so I'm looking for an inexpensive one to replace it with. Thoughts? ---> clicky <---

Ok, how about skipping quality comments and just saying if it'll work?

I think its going to be a bit of a tight fit to put in place of the stock amp. It says its 14.5" long by about 9" wide. Height shouldnt be a problem tho. Measure the footplate and see if you can physically fit it. If not then either consider a dimensionally smaller amp or moving it to a different location.

Maybe I'm missing where that comes in as an "upgrade".. but I know this one will fit..

I have been eyeballing the rockford fosgate punch PBR mini amps. The 300 watt X 4 channel measures;

Dimensions (HxWxL): 1.53" x 4.25" x 6.75"
3.88cm x 10.79cm x 17.14cm

PUNCH Amplifiers - PBR300X4 - Rockford Fosgate®

It uses high level speaker wire inputs and has built in low pass and high pass X-overs. not bad for mid 200's.

Wire the speakers to an aftermarket deck.... bypass the amp. The stock amp puts out 22W to each speaker. My kenwood deck puts out 50W to the door speakers and subs. I just left the 22 watts for the tweeters.

Hmm.. was thinking I had read different...

Each of the six speaker output chips are rated 45 Watts into 2 Ohms, at the chip. There are some losses in the amplifier assembly so real world power is a bit less. This is just shy of 10 VAC sine wave. Aftermarket speakers need more voltage. It is not worth the effort to connect an aftermarket speaker to the OEM amplifier.
Thus my questioning "upgrade"..

This is bad advice there is no Kenwood deck that outputs 50W rms per channel. If it’s a newer deck it’s rated at 22W per channel however all independent test has rated it at 13-14W of useable power per channel.

If its rated at 22W RMS then thats what its constant "usable power" is. I dont agree with 13-14W (Kenwood would have been sued in this sue happy country). In which case it outputs the same as the stock amp, which in turn makes it good advice. Why use the amp if new decks put out the same.... There is also more reasons than just bypassing the amp. You cant argue with quality, having the rear subs hooked to the rear output of the deck and the front to the front, you then get adjustability which you dont have right now.. Also, if the output is less then why did I get more bass out of the subs and overall better quality?????????????? hmmmm....... (Im still almost positive my manual says 50W RMS, but Ill get back to you on that)....

You are completely right and I have no clue what I'm talking about. Best of luck!!
