Upgrading factory system

I have a 94 Nissan Maxima GXE w/o Bose system. I am planning to upgrade the current system and would like to know which component and design best fit my needs. What I'm looking for in a system is exception clarity and a nice level of bass(nothing to excessive but not to light either) GRIN Currently I have 4X6 in the door and 6 1/2 in the rear. I would like to upgrade the rear to 6X9's if possible and may be a small amp....HELP!!! THINK

A better pair of 6.5 coaxials or Component speakers will help a lot for the rear stage segment.

The 4x6" speakers up front are very limited to midrange and highs. If these are dash mounted, see if you have space in the door panels or consider kick panels with 6.5" Comps. (CDT CL-61a is the best value I know of for getting good bass from front and read stage speakers.

As for a good amp, consider the US Acoustics USX (USB) 4085 4 channel amp. Not too expensive, high quality and 85+ watts RMS x 4 at 4 ohms per channel. Plenty of power to run the CDT's

If you have a stock HU now, would be best to use a quality Line out Converter (LOC) mounted near the HU. This adapts speaker level voltages to RCA line level voltages that are appropriate for amplifier inputs. Some models have variable output adjustments.

This one will do nicely.

Product ID: N-774V Category: Adaptor Products
N-774V
Description: The N-774V is a high quality four-channel OEM to aftermarket stereo adaptor that was designed to connect the speaker level output of a factory type deck into the pre-amp level of an equalizer, xover, or amplifier. The signal level can be adjusted from a maximum of 9.5 volts rms down to zero volts. This is a great feature for optimizing the S/N of system and a must for competition or demo systems. Turning the knob clockwise increses the signal level. At the amplifier/speaker we recommend a 1:3 gain structure for most systems. The N-774V features full transformer isolation with maximum useable signal level which means more signal and less noise. The N-774V includes compensation for both frequency and phase with no loss of bass or treble. The maximum signal level output of the N-774V is 9.5 volts per channel.

There ya go for just over $500.00, a first rate upgrade kit.

If that price is out of your budget range, consider Infinity, Alpine or JBL coaxials. Cost a bit less, not the same quality results as CDT speakers, but that amp is a very good option and LOC too.
